48 zhen 1.16 <abstract>These instructions step you through the process of installing Gentoo
49 antifa 1.105 Linux 1.4_rc4. The Gentoo Linux installation process supports various installation
50 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
51     scratch.

56     <title>About the Install</title>
57     <section>
58     <body>
59 zhen 1.26 <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
60 jhhudso 1.71 as many SCSI CD-ROM drives, assuming that your CD-ROM and BIOS both support booting.
61 drobbins 1.21 Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
62     kernel) as well as support for all SCSI devices (available as modules.) In
63     addition, we provide modules for literally every kind of network card that
64     Linux supports, as well as tools to allow you to configure your network and
65 jhhudso 1.75 establish outbound (as well as inbound) <c>ssh</c> connections and to download
66 drobbins 1.21 files. </p>
67 zhen 1.26 <p>To install from the build CD, you will need to have a 486+ processor and
68 drobbins 1.69 ideally at least 64 Megabytes of RAM. (Gentoo Linux has been successfully
69 drobbins 1.21 built with 64MB of RAM + 64MB of swap space, but the build process is awfully
70     slow under those conditions.)</p>
71 zhen 1.26 <p>Gentoo Linux can be installed using one of three &quot;stage&quot; tarball files. The
72 drobbins 1.21 one you choose depends on how much of the system you want to compile yourself.
73 jhhudso 1.75 The stage1 tarball is used when you want to bootstrap and build the entire
74 drobbins 1.21 system from scratch. The stage2 tarball is used for building the entire system
75 jhhudso 1.75 from a bootstrapped state. The stage3 tarball already contains a basic Gentoo Linux system.</p>
76 drobbins 1.70 <p><b>So, should you choose to start from a stage1, stage2, or stage3 tarball?</b>
77     Starting from a stage1 allows you to have total control over the optimization settings
78     and optional build-time functionality that is initially enabled on your system. This
79 jhhudso 1.75 makes stage1 installs good for power users who know what they are doing. Stage2 installs
80     allow you to skip the bootstrap process, and doing this is fine if you are happy with
81 drobbins 1.70 the optimization settings that we chose for your particular stage2 tarball. Choosing to
82     go with a stage3 allows for the fastest install of Gentoo Linux, but also means that
83 jhhudso 1.75 your base system will have the optimization settings that we chose for you. Since major
84     releases of Gentoo Linux have stage3's specifically optimized for various popular processors,
85     this may be sufficient for you. <b>If you're installing Gentoo Linux for the first time, consider
86 drobbins 1.70 using a stage3 tarball for installation.</b></p>
89 jhhudso 1.75 <p> So, how does one begin the install process? First, you will want to decide which one of our LiveCD ISO images to grab from
90 antifa 1.105 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc4/x86/</uri> . Please consider using one of our mirrors to alleviate the heavy load from
91 peesh 1.100 the main server. A list of servers can be found at <uri>http://www.gentoo.org/main/en/mirrors.xml</uri>.
92 drobbins 1.22 </p>
93 zhen 1.26 <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
94 jhhudso 1.75 using CD burning software. Currently, we have two types of LiveCDs. The first
95     carries the &quot;gentoo-basic&quot; label, and is approximately 40MB in size, contains only the stage 1 tarball and lives
96 drobbins 1.24 in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
97     allow for a initial quick download and contains a stage1 tarball that can be
98     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
99 seemant 1.78 <p>The second flavor of LiveCD we currently offer is labeled &quot;gentoo-3stages.&quot;
100 jhhudso 1.75 This CD is also found in <path>x86/livecd</path>. It
101 jhhudso 1.77 contains stage 1, 2 and 3 tarballs. Using this LiveCD, it will be possible
102 jhhudso 1.75 for you to install a fully-functional Gentoo Linux system very quickly.</p>
103 jhhudso 1.77 <p><b>What happened to i686, pentium3, athlon, athlon-mp stages, LiveCDs and GRP (Gentoo Reference Platform)?</b>
104 swift 1.107 Gentoo 1.4_rc4 is meant to be a minimal release candidate only. 1.4_final will contain all the usual x86 architectures and GRP. If you want to install stages optimized for these other x86 architectures or GRP, use the 1.4_rc2 documentation, which can be found at <uri>http://www.gentoo.org/doc/en/gentoo-x86-1.4_rc2-install.xml</uri>
105 jhhudso 1.77 </p>
106 drobbins 1.70 <impo>If you encounter a problem with any part of the install and wish to
107 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
108 jhhudso 1.75 needs to be sent upstream to the original software developers (eg the KDE team) the
109 drobbins 1.70 <e>Gentoo Linux developers</e> will take care of that for you.
110     </impo>
111 jhhudso 1.75 <p>Now, let us quickly review the install process. First, we will download, burn
112     and boot a LiveCD. After getting a root prompt, we will create partitions, create
113 drobbins 1.21 our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
114     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
115 jhhudso 1.75 our system to stage3. Once our system is at stage3, we can configure it
116 seemant 1.78 (customize configuration files, install a boot loader, etc) and boot it and have a
117 drobbins 1.21 fully-functional Gentoo Linux system. Depending on what stage of the build
118 jhhudso 1.75 process you're starting from, here is what is required for installation: </p>

213 jhhudso 1.75 <p> Once you hit Enter, you will be greeted with the standard kernel
214     booting output, kernel and initrd messages, followed by the normal Gentoo
215     Linux boot sequence. You will be automatically logged in as
216     &quot;<c>root</c>&quot; and the root password will be set to a random string
217     for security purposes. You should have a root (&quot;<c>#</c>&quot;) prompt
218 seemant 1.78 on the current console, and can also switch to other consoles by pressing
219 jhhudso 1.75 Alt-F2, Alt-F3 and Alt-F4. Get back to the one you started on by pressing
220 peesh 1.110 Alt-F1. At this point you should set the root password, type <c>passwd</c> and
221 jhhudso 1.75 follow the prompts.

472 zhen 1.16 <section>
473 drobbins 1.86 <title>Introduction to block devices</title>
474 zhen 1.16 <body>
475 drobbins 1.86 <p>
476     In this section, we'll take a good look at disk-oriented aspects of Gentoo Linux and Linux in general, including
477 peesh 1.99 Linux filesystems, partitions and block devices. Then, once you're familiar with the ins and outs of disks and
478 drobbins 1.86 filesystems, you'll be guided through the process of setting up partitions and filesystems for your Gentoo Linux
479     install.
480     </p>
481     <p>
482     To begin, I'll introduce "block devices". The most famous block device is
483     probably the one that represents the first IDE drive in a Linux system:
484     </p>
485     <pre caption="/dev/hda, the block device representing the primary master IDE drive in your system">
486     /dev/hda
487     </pre>
489     <p>
490     If your system uses SCSI drives, then your first hard drive will be:
491     </p>
493     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
494     /dev/sda
495     </pre>
497     <p>The block devices above represent an <i>abstract</i> interface to the disk.
498     User programs can use these block devices to interact with your disk without
499     worrying about whether your drivers are IDE, SCSI or something else. The
500     program can simply address the storage on the disk as a bunch of contiguous,
501     randomly-accessible 512-byte blocks. </p>
502     </body>
503     </section>
504     <section>
505     <title>Partitions and fdisk</title>
506     <body>
507     <p> Under Linux, we create filesystems by using a special command called
508     <c>mkfs</c> (or <c>mke2fs</c>, <c>mkreiserfs</c>, etc,) specifying a particular
509     block device as a command-line argument. </p>
511     <p> However, although it is theoretically possible to use a "whole disk" block
512     device (one that represents the <i>entire</i> disk) like <c>/dev/hda</c> or
513     <c>/dev/sda</c> to house a single filesystem, this is almost never done in
514     practice. Instead, full disk block devices are split up into smaller, more
515 peesh 1.99 manageable block devices called "partitions". Partitions are created using a
516 drobbins 1.86 tool called <c>fdisk</c>, which is used to create and edit the partition table
517     that's stored on each disk. The partition table defines exactly how to split
518     up the full disk. </p>
520     <p> We can take a look at a disk's partition table by running <c>fdisk</c>,
521     specifying a block device that represents a full disk as an argument: </p>
523     <note>Alternate interfaces to the disk's partition table include <c>cfdisk</c>,
524     <c>parted</c> and <c>partimage</c></note>
526     <pre caption="Starting up fdisk">
527     # fdisk /dev/hda

530     or
531     </p>
532     <pre caption="Starting up fdisk to look at the partition table on /dev/sda">
533     # fdisk /dev/sda
534     </pre>
536     <impo>
537     <b>Note that you should <i>not</i> save or make any changes to a disk's
538     partition table if any of its partitions contain filesystems that are in use or
539     contain important data. Doing so will generally cause data on the disk to be
540     lost.</b>
541     </impo>
543     <p>
544     Once in fdisk, you'll be greeted with a prompt that looks like this:

574     </pre>
576     <p> This particular disk is configured to house seven Linux filesystems (each
577     with a corresponding partition listed as "Linux") as well as a swap partition
578     (listed as "Linux swap"). </p>
580     <p>
581     Notice the name of the corresponding partition block
582     devices on the left hand side, starting with <c>/dev/hda1</c> and going up to
583     <c>/dev/hda9</c>. In the early days of the PC, partitioning software only
584     allowed a maximum of four partitions (called "primary" partitions). This was
585     too limiting, so a workaround called an <i>extended partitioning</i> was
586     created. An extended partition is very similar to a primary partition, and
587     counts towards the primary partition limit of four. However, extended
588     partitions can hold any number of so-called <i>logical</i> partitions inside
589     them, providing an effective means of working around the four partition limit.
590     </p>
592     <p>
593     All partitions <c>hda5</c> and higher are logical partitions. The numbers 1
594     through 4 are reserved for primary or extended partitions. </p>
596     <p> So, In our example, <c>hda1</c> through <c>hda3</c> are primary partitions.
597     <c>hda4</c> is an extended partition that contains logical partitions
598 drobbins 1.87 <c>hda5</c> through <c>hda9</c>. You would never actually
599 drobbins 1.86 <i>use</i> <c>/dev/hda4</c> for storing any filesystems directly -- it simply
600     acts as a container for partitions <c>hda5</c> through <c>hda9</c>. </p>
602     <p> Also, notice that each partition has an "Id", also called a "partition
603     type". Whenever you create a new partition, you should ensure that the
604     partition type is set correctly. '83' is the correct partition type for
605 swift 1.115 partitions that will be housing Linux filesystems, '82' is the correct
606     partition type for Linux swap partitions and 'fd' is the recommended partition
607     type for Software RAID partitions. You set the partition type using the
608 drobbins 1.86 <c>t</c> option in <c>fdisk</c>. The Linux kernel uses the partition type
609 peesh 1.99 setting to auto-detect filesystems and swap devices on the disk at boot-time.

614     <title>Using fdisk to set up partitions</title>
615     <body>
617 drobbins 1.87 <p>Now that you've had your introduction to the way disk partitioning is
618 drobbins 1.86 done under Linux, it's time to walk you through the process of setting up disk
619     partitions for your Gentoo Linux installation. After we walk you through the
620     process of creating partitions on your disk, your partition configuration will
621     look like this: </p>
623     <pre caption="The partition configuration that you will have after following these steps">
624     Disk /dev/hda: 30.0 GB, 30005821440 bytes
625     240 heads, 63 sectors/track, 3876 cylinders
626     Units = cylinders of 15120 * 512 = 7741440 bytes
628     Device Boot Start End Blocks Id System
629     /dev/hda1 * 1 14 105808+ 83 Linux
630     /dev/hda2 15 81 506520 82 Linux swap
631     /dev/hda3 82 3876 28690200 83 Linux
633     Command (m for help):
634     </pre>
636     <p>In our suggested "newbie" partition configuration, we have three partitions.
637     The first one (<c>/dev/hda1</c>) at the beginning of the disk is a small
638     partition called a boot partition. The boot partition's purpose is to hold all
639     the critical data related to booting -- GRUB boot loader information (if you
640     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
641     us a safe place to store everything related to booting Linux. During normal
642     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
643 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
644     likely end up being <c>/dev/sda1</c>.</p>
645 drobbins 1.86
646 drobbins 1.98 <p>It's recommended to have boot partitions (containing everything necessary for
647     the boot loader to work) at the beginning of the disk. While not necessarily
648     required anymore, it is a useful tradition from the days when the lilo boot
649     loader wasn't able to load kernels from filesystems that extended beyond disk
650     cylinder 1024.
651     </p>
653 drobbins 1.86 <p>The second partition (<c>/dev/hda2</c>) is used to for swap space. The
654     kernel uses swap space as virtual memory when RAM becomes low. This partition,
655     relatively speaking, isn't very big either, typically somewhere around 512MB.
656 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
657     being called <c>/dev/sda2</c>. </p>
658 drobbins 1.86
659     <p>The third partition (<c>/dev/hda3</c>) is quite large and takes up the rest
660     of the disk. This partition is called our "root" partition and will be used to
661     store your main filesystem that houses Gentoo Linux itself. On a SCSI system,
662     this partition would likely end up being <c>/dev/sda3</c>.</p>
665     <p>Before we partition the disk, here's a quick technical overview of the
666     suggested partition and filesystem configuration to use when installing Gentoo
667     Linux:</p>

681     </tr>
682     <tr>
683     <ti>swap partition (no longer a 128 Megabyte limit, now 2GB)</ti>
684     <ti>Generally, configure a swap area that is between one to two times the size of the physical RAM

692     <ti>ReiserFS, ext3 recommended; ext2 ok</ti>
693     <ti>/dev/hda3</ti>
694     </tr>
695     </table>
697     <p>OK, now to create the partitions as in the example and table above. First,
698 swift 1.95 enter fdisk by typing <c>fdisk /dev/hda</c> or <c>fdisk /dev/sda</c>,
699 drobbins 1.86 depending on whether you're using IDE or SCSI. Then, type <c>p</c> to view your
700     current partition configuration. Is there anything on the disk that you need
701     to keep? If so, <b>stop now</b>. If you continue with these directions, <b>all
702     existing data on your disk will be erased.</b></p>
704     <impo>Following these instructions below will cause all prior data on your disk
705     to <b>be erased</b>! If there is anything on your drive, please be sure that it
706     is non-critical information that you don't mind losing. Also make sure that you
707     <b>have selected the correct drive</b> so that you don't mistakenly wipe data
708     from the wrong drive.</impo>
710     <p>Now, it's time to delete any existing partitions. To do this, type <c>d</c>
711     and hit Enter. You will then be prompted for the partition number you would like
712     to delete. To delete a pre-existing <c>/dev/hda1</c>, you would type:</p>
714     <pre caption="Deleting a partition">
715     Command (m for help): d
716     Partition number (1-4): 1
717     </pre>
718 zhen 1.54
719 drobbins 1.86 <p>The partition has been scheduled for deletion. It will no longer show up if
720     you type <c>p</c>, but it will not be erased until your changes have been
721     saved. If you made a mistake and want to abort without saving your changes,
722     type <c>q</c> immediately and hit enter and your partition will not be
723     deleted.</p>
724     <!-- NOTE: THis is not sufficient documentation to cover ATA Raid and I just
725     find it confusing, so I'm commenting it out (drobbins)
726     <note>If you are using RAID your partitions will be a little different. You
727 jhhudso 1.75 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X are

729     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
730 drobbins 1.86 -->
731     <p>Now, assuming that you do indeed want to wipe out all the partitions on your
732     system, repeatedly type <c>p</c> to print out a partition listing and then type
733     <c>d</c> and the number of the partition to delete it. Eventually, you'll end up
734     with a partition table with nothing in it:</p>
736     <pre caption="An empty partition table">

743     Command (m for help):
744     </pre>
746     <p>Now that the in-memory partition table is empty, we're ready to create a
747     boot partition. To do this, type <c>n</c> to create a new partition, then
748     <c>p</c> to tell fdisk you want a primary partition. Then type <c>1</c> to
749     create the first primary partition. When prompted for the first cylinder, hit
750 swift 1.115 enter. When prompted for the last cylinder, type <c>+32M</c> to create a
751     partition 32MB in size. You can see output from these steps below:</p>
753     <note>
754     Journaled filesystems require extra space for their journal. Default settings
755     require about 33 Megabytes of space. Therefor, if you are using a journaled
756     filesystem for <path>/boot</path>, you should type <c>+64M</c> when prompted

843     <title>Creating filesystems</title>
844     <body>
845     <p>Now that the partitions have been created, it's time to set up filesystems on
846     the boot and root partitions so that they can be mounted and used to store data.
847     We will also configure the swap partition to serve as swap storage.
848     </p>
850     <p>Gentoo Linux supports a variety of different types of filesystems; each type has
851     its strengths and weaknesses and its own set of performance characteristics. Currently,
852     we support the creation of ext2, ext3, XFS, JFS and ReiserFS filesystems.</p>
854     <p>ext2 is the tried and true Linux filesystem but doesn't have metadata
855     journaling, which means that routine ext2 filesystem checks at startup time can
856     be quite time-consuming. There is now quite a selection of newer-generation
857     <i>journaled</i> filesystems that can be checked for consistency very quickly
858     and are thus generally preferred over their non-journaled counterparts.
859     Journaled filesystems prevent long delays when you boot your system and your
860     filesystem happens to be in an <i>inconsistent</i> state.</p>
862     <p>ext3 is the journaled version of the ext2 filesystem, providing metadata
863     journaling for fast recovery in addition to other enhanced journaling modes
864     like full data and ordered data journaling. ext3 is a very good and reliable
865 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
866     Because it does not extensively employ the use of "trees" in its internal
867     design, it doesn't scale very well, meaning that it is not an ideal choice for
868     very large filesystems, or situations where you will be handling very large
869     files or large quantities of files in a single directory. But when used within
870     its design parameters, ext3 is an excellent filesystem.</p>
871 drobbins 1.86
872     <p>ReiserFS is a B*-tree based filesystem that has very good overall
873     performance and greatly outperforms both ext2 and ext3 when dealing with small
874     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
875     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
876     now rock-solid and highly recommended for use both as a general-purpose
877     filesystem and for extreme cases such as the creation of large filesystems, the
878     use of many small files, very large files, and directories containing tens of
879     thousands of files. ReiserFS is the filesystem we recommend by default for all
880     non-boot partitions.</p>
882     <p>XFS is a filesystem with metadata journaling that is fully supported under
883     Gentoo Linux's <path>xfs-sources</path> kernel. It comes with a robust
884     feature-set and is optimized for scalability. We only recommend using this
885     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
886     a uninterruptible power supply. Because XFS aggressively caches in-transit data
887     in RAM, improperly designed programs (those that don't take proper precautions
888     when writing files to disk, and there are quite a few of them) can lose a good
889     deal of data if the system goes down unexpectedly.</p>
891     <p>JFS is IBM's own high performance journaling filesystem. It has recently
892     become production-ready, and there hasn't been a sufficient track record to
893     comment either positively nor negatively on its general stability at this
894     point.</p>
896     <p>If you're looking for the most rugged journaling filesystem, use ext3. If
897     you're looking for a good general-purpose high-performance filesystem with
898     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
899     refined and recommended for general use.</p>
901     <!-- Corner case, confusing
902 drobbins 1.70 <p>But before creating filesystems, you may want to initialize the
903 jhhudso 1.81 beginning of your partition using <c>dd</c> if you are using a pre-existing partition that has been used before.
904 drobbins 1.70 This is particularly helpful when you're going to create a new XFS filesystem on a partition that previously contained
905     a ReiserFS filesystem. Doing this will ensure that your new filesystem
906 seemant 1.78 will not be mis-identified by Linux's filesystem auto-detection code.
907 drobbins 1.21 This can be done as follows:

914 zhware 1.43 Be careful and check twice which partition you specify for zeroing.

916     </warn>
917 drobbins 1.86 -->
919     <p>Based on our example above, we will use the following commands to initialize
920     all our partitions for use:</p>
922     <pre caption="Initializing our partitions (example)">
923     # mke2fs -j /dev/hda1
924     # mkswap /dev/hda2
925     # mkreiserfs /dev/hda3
926     </pre>
928 drobbins 1.98 <p>We choose ext3 for our <c>/dev/hda1</c> boot partition because it is a
929     robust journaling filesystem supported by all major boot loaders. We used
930     <c>mkswap</c> for our <c>/dev/hda2 </c> swap partition -- the choice is obvious
931     here. And for our main root filesystem on <c>/dev/hda3</c> we choose ReiserFS,
932     since it is a solid journaling filesystem offering excellent performance. Now,
933     go ahead and initialize your partitions.</p>
935     <p>For your reference, here are the various <c>mkfs</c>-like commands available
936     during the installation process:</p>
937 drobbins 1.86
938 drobbins 1.89 <p><c>mkswap</c> is the command that is used to initialize swap partitions:</p>

940 drobbins 1.1 # <c>mkswap /dev/hda2</c>
941 jhhudso 1.81 </pre>
942 drobbins 1.89 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems:</p>

944 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
945 jhhudso 1.81 </pre>
946 drobbins 1.86 <p>If you would like to use ext3, you can create ext3 filesystems using
947 drobbins 1.89 <c>mke2fs -j</c>:</p>
948 drobbins 1.86 <pre caption="Creating an ext3 Filesystem">

952     <uri>http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html</uri>.</note>
953 drobbins 1.89 <p>To create ReiserFS filesystems, use the <c>mkreiserfs</c> command:</p>
954 drobbins 1.86 <pre caption="Creating a ReiserFS Filesystem">
955     # <c>mkreiserfs /dev/hda3</c>
956     </pre>
957 drobbins 1.89 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command:</p>
958 jhhudso 1.81 <pre caption="Creating a XFS Filesystem">
959 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
960 jhhudso 1.81 </pre>
961     <note>You may want to add a couple of additional flags to the
962     <c>mkfs.xfs</c> command: <c>-d agcount=3 -l size=32m</c>.
963     The <c>-d agcount=3</c> command will lower the number of allocation groups.
964     XFS will insist on using at least 1 allocation group per 4 GB of your
965     partition, so, for example, if you have a 20 GB partition you will need
966     a minimum agcount of 5. The <c>-l size=32m</c> command increases the
967     journal size to 32 Mb, increasing performance.</note>
968 drobbins 1.86
969 drobbins 1.89 <p>To create JFS filesystems, use the <c>mkfs.jfs</c> command:</p>

987 jhhudso 1.75 <p>Next, we will create the <path>/mnt/gentoo</path> and <path>/mnt/gentoo/boot</path> mount points,
988 zhen 1.93 and we will mount our filesystems to these mount points. Once our boot and root filesystems are
989 drobbins 1.86 mounted, any files we copy or create inside <path>/mnt/gentoo</path> will be placed on our new filesystems.
990     Note that if you are setting up Gentoo
991     Linux with separate <path>/usr</path> or <path>/var</path> filesystems, these would get mounted to
992     <path>/mnt/gentoo/usr</path> and <path>/mnt/gentoo/var</path> respectively.

995     <impo>If your <e>boot</e> partition (the one holding the kernel) is ReiserFS, be sure to mount it

1132     <p>Now that you have a working copy of the Portage tree, it is time to
1133     customize the optimization and optional build-time settings to use on your
1134     Gentoo Linux system. Portage will use these settings when compiling any
1135     programs for you. To do this, edit the file <path>/etc/make.conf</path>. In
1136     this file, you should set your <c>USE</c> flags, which specify optional
1137     functionality that you would like to be built into packages if available;
1138     generally, the defaults (an <e>empty</e> or unset <c>USE</c> variable) are
1139     fine. More information on <c>USE</c> flags can be found <uri
1140     link="http://www.gentoo.org/doc/en/use-howto.xml">here</uri>. A complete list
1141     of current USE flags can be found <uri
1142     link="http://www.gentoo.org/dyn/use-index.xml">here</uri>. </p>
1144     <p>You also should set appropriate <c>CHOST</c>, <c>CFLAGS</c> and
1145     <c>CXXFLAGS</c> settings for the kind of system that you are creating
1146     (commented examples can be found further down in the file.) These settings
1147     will be used to tell the C and C++ compiler how to optimize the code that
1148     is generated on your system. It is common for users with Athlon XP processors
1149     to specify a "-march=athlon-xp" setting in their CFLAGS and CXXFLAGS settings
1150     so that all packages built will be optimized for the instruction set and
1151     performance characteristics of their CPU, for example. The <path>/etc/make.conf</path>
1152     file contains a general guide for the proper settings of CFLAGS and CXXFLAGS.</p>
1153 drobbins 1.70
1154 drobbins 1.86 <p>If necessary, you can also set proxy information here if you are behind a
1155     firewall. Use the following command to edit <path>/etc/make.conf</path> using <c>nano</c>,
1156     a simple visual editor.

1162 zhen 1.16 <note>
1163 jhhudso 1.75 People who need to substantially customize the build process should take a look at
1164 zhen 1.6 the <path>/etc/make.globals</path> file. This file comprises gentoo defaults and
1165 drobbins 1.70 should never be touched. If the defaults do not suffice, then new values should

1167     <comment>override</comment> the entries in <path>make.globals</path>. If you're
1168 jhhudso 1.75 interested in customizing USE settings, look in <path>/etc/make.profile/make.defaults</path>.
1169 zhen 1.16 If you want to turn off any USE settings found here, add an appropriate <c>USE=&quot;-foo&quot;</c>
1170 drobbins 1.86 in <path>/etc/make.conf</path> to turn off any <c>foo</c> USE setting enabled by default
1171     in <path>/etc/make.globals</path> or <path>/etc/make.profile/make.defaults</path>.

1180 drobbins 1.86 <note>If you are not starting from a stage1 tarball, skip this section.</note>
1181 jhhudso 1.75 <p>The stage1 tarball is for complete customization and optimization. If you have picked this tarball,
1182 drobbins 1.86 you are most likely looking to have an uber-optimized and up-to-date system. Have fun, because optimization
1183 drobbins 1.70 is what Gentoo Linux is all about! Installing from a stage1 takes a lot of time, but the result
1184     is a system that has been optimized from the ground up for your specific machine and needs.
1185 zhen 1.18 </p>
1186 jhhudso 1.75 <p>Now, it is time to start the &quot;bootstrap&quot; process. This process takes about two hours on
1187 peesh 1.99 my 1200MHz AMD Athlon system.
1188 drobbins 1.86 During this time, the GNU C library, compiler suite and other key system programs will be built. Start the bootstrap
1189     as follows:</p>
1190 jhhudso 1.81 <pre caption="Bootstrapping">
1191 drobbins 1.1 # <c>cd /usr/portage</c>
1192     # <c>scripts/bootstrap.sh</c>
1193 jhhudso 1.81 </pre>
1194 zhen 1.16 <p>The &quot;bootstrap&quot; process will now begin.
1195 zhen 1.6 </p>
1196 zhen 1.16 <note>
1197 zhen 1.6 Portage by default uses <c>/var/tmp</c> during package building, often
1198     using several hundred megabytes of temporary storage. If you would like to
1199     change where Portage stores these temporary files, set a new PORTAGE_TMPDIR <e>before</e>
1200     starting the bootstrap process, as follows:
1201     </note>

1207     after <c>glibc</c>. Needless to say, this process takes a while.
1208 jhhudso 1.75 Once this process completes, your system will be equivalent to a &quot;stage2&quot; system,
1209 zhen 1.33 which means you can now move on to the stage2 instructions.

1255 drobbins 1.108
1256 drobbins 1.86 <p>The stage3 tarball provides a fully-functional basic Gentoo system, so no building is required.
1257     However, since the stage3 tarball is pre-built, it may be slightly out-of-date. If this is a concern
1258 drobbins 1.108 for you, you can automatically update your existing stage3 to contain the most up-to-date versions of all system packages
1259 drobbins 1.86 by performing the following steps. Note that this could take a long time if your stage3 is very old;
1260     otherwise, this process will generally be quick and will allow you to benefit from the very latest
1261     Gentoo updates and fixes.
1262     In any case, feel free to skip these
1263     steps and proceed to the next section if you like.

1401     controllers and Support Promise software RAID (Fasttrak(tm))
1402     </p>
1403 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
1404 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
1405 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
1406     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but

1418 zhen 1.16 <note>
1419 zhen 1.6 For those who prefer it,
1420     it is now possible to install Gentoo Linux with a 2.2 kernel.
1421 drobbins 1.21 However, doing this comes at a price:
1422 zhen 1.6 you will lose many of the nifty features that
1423     are new to the 2.4 series kernels (such as XFS and tmpfs
1424     filesystems, iptables, and more), although the 2.2 kernel sources can be
1425 drobbins 1.21 patched with ReiserFS and devfs support.
1426     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
1427 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
1428     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
1429 peesh 1.103 line in <path>/boot/grub/grub.conf</path> or to the append line in <path>/etc/lilo.conf</path> for the 2.2 kernel so
1430 peesh 1.85 that a ramdisk is mounted for the boot scripts instead of tmpfs. If you choose not to use devfs, then
1431 zhen 1.6 <e>gentoo=notmpfs,nodevfs</e> should be used instead.
1432     </note>
1433 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
1434 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
1435     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
1436     to gravitate away from sysklogd (not very good performance) and towards the
1437     newer alternatives.
1438     If in doubt, you may want to try metalog, since it seems to be quite popular.

1457     is less than helpful. When your Gentoo Linux system is up and running, you can send

1460     in real time, as expected),
1461     and a USR2 signal to turn buffering back on
1462 zhen 1.39 again. If you want to disable buffering permanently, you can change METALOG_OPTS="-B" to METALOG_OPTS="-B -s"

1684     <p> In the spirit of Gentoo, users now have more than one bootloader to choose from.
1685     Using our virtual package system, users are now able to choose between both GRUB and
1686     LILO as their bootloaders.
1687     </p>
1688     <p> Please keep in mind that having both bootloaders installed is not necessary.
1689 jhhudso 1.75 In fact, it can be a hindrance, so please only choose one.
1690 zhen 1.49 </p>
1691 drobbins 1.69 <impo>If you are installing Gentoo Linux on a system with an NVIDIA nForce or nForce2 chipset
1692     with an integrated GeForce graphics card, you should use LILO and avoid GRUB. With on-board
1693 drobbins 1.70 video enabled, the low memory area of your RAM may be used as video RAM. Since GRUB also uses low
1694     memory at boot time, it may experience an "out of memory" condition. So, if you have an nForce
1695 drobbins 1.69 or potentially other board with on-board video, use LILO. Even if you're using off-board video
1696 jhhudso 1.75 right now, it would be nice to be able to remove the graphics card and use the on-board video in a
1697 drobbins 1.69 pinch, wouldn't it? :)</impo>

1710 zhen 1.49 <title>Configuring GRUB</title>
1711 zhen 1.16 <body>
1712     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1713 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1714     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1715 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1716 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1717     cdrom players, burners, and that the same construct can be used with scsi drives.
1718     (Normally they get higher numbers than ide drives except when the bios is configured
1719     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1720 peesh 1.103 a burner on /dev/hdc, a second hard drive on /dev/hdd and no scsi harddrive,
1721 zhen 1.6 <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1723     It might sound tricky, and tricky it is indeed, but as we will see, grub
1724     offers a tab completion mechanism that comes handy for those of you having
1725     a lot of harddrives and partitions and who are a little lost in the
1726     grub numbering scheme. Having gotten the feel for that,
1727 jhhudso 1.75 it is time to install GRUB.
1728 zhen 1.6 </p>
1729 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1730 jhhudso 1.81 <pre caption="Installing GRUB">
1731 zhen 1.51 # <c>emerge grub</c>
1732 drobbins 1.1 # <c>grub</c>
1733 jhhudso 1.81 </pre>
1734 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1735 zhen 1.6 this time.
1736     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1737     grub setup for RAID controllers
1738     </impo>
1739 jhhudso 1.75 <p>You will be presented with the <c>grub&gt;</c> grub
1740 zhen 1.6 command-line prompt. Now, you need to type in the
1741     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1742     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1743     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1744     I want to type are:
1745     </p>
1746 zhen 1.68
1747 jhhudso 1.81 <pre caption="GRUB on the MBR">
1748 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>

1750 jhhudso 1.81 </pre>
1751 zhen 1.68
1752 jhhudso 1.81 <pre caption="GRUB not on the MBR">
1753 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
1754 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
1755     grub&gt; <c>setup (hd0,4)</c> <codenote>Where the boot record is installed, here it is /dev/hda5</codenote>
1756 drobbins 1.1 grub&gt; <c>quit</c>
1757 jhhudso 1.81 </pre>
1758 zhen 1.68
1759 jhhudso 1.75 <p>Here is how the two commands work. The first <c>root ( )</c> command tells GRUB
1760 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1761     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1762     </c> command tells GRUB where to install the
1763     boot record - it will be configured to look for its special files at the <c>root
1764     ( )</c> location that you specified. In my case, I want the boot record on the
1765     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1766     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1767     could install GRUB to the boot record of a particular partition. In that case,
1768 jhhudso 1.75 I would specify a particular partition rather than the entire disk. Once the GRUB
1769 zhen 1.6 boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1770 zhen 1.52 </p>
1771 zhen 1.6
1772     <note> The tab completion mechanism of grub can be used from within grub,
1773     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1774     be prompted with a list of the available devices (not only harddrives),
1775     hitting the TAB key having written <c> root (hd</c>, grub would print the
1776     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1777     would make grub print the list of partitions on the first harddrive.
1779     Checking the syntax of the grub location with completion should really help
1780     to make the right choice.
1781     </note>
1783 zhen 1.52 <p>
1784 zhen 1.6 Gentoo Linux is now
1785     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1786 jhhudso 1.75 we get a nice GRUB boot menu when the system reboots. Here is how to do it.
1787 zhen 1.6 </p>
1788 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1789 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1790     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1791 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:

1817 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1818     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1819 zhen 1.6 </impo>
1820 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1821 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1822     and shows you how to use GRUB to boot a bootable Windows partition.
1823     </p>
1824 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1825 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1826     your root filesystem. <path>(hd0,5)</path> contains the NT boot
1827     loader.
1828 zhware 1.9 </note>
1829 zhen 1.16 <note>
1830 zhware 1.9 The path to the kernel image is relative to the boot partition. If for example you have separated boot partition <path>(hd0,0)</path> and root partition <path>(hd0,1)</path>, all paths in the grub.conf file above will become <path>/bzImage</path>.
1831 zhen 1.6 </note>
1832 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1833 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1834     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1835     turn off devfs by default (not recommended unless you know what you're doing) by
1836     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1837     </p>
1838 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1839 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1840     devfs is enabled by default.

1845     <title>Configuring LILO</title>
1846 zhen 1.16 <body>
1847 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1848 jhhudso 1.75 LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here is how to install
1849 drobbins 1.21 LILO if you would like to use it instead of GRUB:
1850 zhen 1.16 </p>
1851     <p>The first step is to emerge LILO:
1852     </p>
1853 jhhudso 1.81 <pre caption="Emerging LILO">
1854 zhen 1.16 # <c>emerge lilo</c>
1855 jhhudso 1.81 </pre>
1856 zhen 1.82 <p>Now it is time to configure LILO. Here is a sample configuration file <path>/etc/lilo.conf</path>
1857 zhen 1.16 </p>
1858 jhhudso 1.81 <pre caption="Example lilo.conf">
1859 zhen 1.16 boot=/dev/hda
1860     map=/boot/map
1861     install=/boot/boot.b
1862     prompt
1863     timeout=50
1864     lba32
1865     default=linux
1867 swift 1.111 image=/boot/bzImage
1868 zhen 1.16 label=linux
1869     read-only
1870 zhen 1.82 root=/dev/hda3
1871 zhen 1.16
1872     #For dual booting windows/other OS
1873     other=/dev/hda1
1874     label=dos
1875 jhhudso 1.81 </pre>
1876 zhen 1.52 <ul>
1877 zhen 1.16 <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
1878     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1879     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1880     In normal use, this should not be altered. If the install line is missing, LILO will
1881     assume a default of /boot/boot.b as the file to be used. </li>
1882 zhen 1.83 <li>The existence of <i>prompt</i> tells LILO to display the classic <i>lilo:</i> prompt at bootup.
1883 zhen 1.16 While it is not recommended that you remove the prompt line, if you do remove it, you can still
1884     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1885     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1886     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1887     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1888     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1889     your system in an unbootable state. </li>
1890     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1891     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1892 swift 1.111 <li><i>image=/boot/bzImage</i> specifies the linux kernel to boot with this particular boot option. </li>
1893 zhen 1.16 <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1894     it is also the name referred to by the default line. </li>
1895     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1896     altered during the boot process. </li>
1897     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1898 zhen 1.52 </ul>
1899 zhen 1.16 <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information
1900     into the MBR:
1901     </p>
1902 jhhudso 1.81 <pre caption="Running LILO">
1903 zhen 1.16 # <c>/sbin/lilo</c>
1904 jhhudso 1.81 </pre>
1905 zhen 1.16 <p>LILO is configured, and now your machine is ready to boot into Gentoo Linux!

1913     <title>GRUB Bootdisks</title>
1914     <body>
1915 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1916 zhen 1.16 time you install any Linux distribution. This is a security
1917 peesh 1.103 blanket, and generally not a bad thing to do. If you are using some kinds of hardware RAID, you may <e>need</e> to make a GRUB boot
1918 drobbins 1.21 disk. With these types of hardware RAID,
1919     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1920     make a GRUB
1921     boot disk, and when you reboot the first time you can install GRUB
1922 zhen 1.6 to the MBR. Make your
1923 jhhudso 1.75 bootdisks like this:
1924 zhen 1.6 </p>
1925 jhhudso 1.81 <pre caption="Creating a GRUB Bootdisk">
1926 swift 1.116 # <c>cd /usr/share/grub/i386-pc/</c>
1927     # <c>cat stage1 stage2 > /dev/fd0</c>
1928 jhhudso 1.81 </pre>
1929 zhen 1.26 <p>Now reboot and load the floppy. At the floppy's <c>grub&gt;</c> prompt, you can now execute the necessary <c>root</c>
1930 drobbins 1.21 and <c>setup</c> commands.</p>

1935     <body>
1936     <p>If you are using LILO, it is also a good idea to make a bootdisk:
1937     </p>
1938 jhhudso 1.81 <pre caption="Making a LILO Bootdisk">
1939 zhen 1.18 # <c>dd if=/boot/your_kernel of=/dev/fd0 </c>

1947     <section>
1948     <body>
1949 jhhudso 1.75 <p>Now, Gentoo Linux is installed. The only remaining step is to update necessary configuration files, exit the chrooted shell,
1951 zhen 1.6 safely unmount your partitions
1952     and reboot the system:
1953     </p>
1954 jhhudso 1.81 <pre caption="Rebooting the System">
1955 drobbins 1.1 # <c>etc-update</c>
1956     # <c>exit</c>
1957 jhhudso 1.81 <comment>(This exits the chrooted shell; you can also type <c>^D</c>)</comment>
1958 drobbins 1.1 # <c>cd / </c>
1959     # <c>umount /mnt/gentoo/boot</c>
1960     # <c>umount /mnt/gentoo/proc</c>
1961     # <c>umount /mnt/gentoo</c>
1962     # <c>reboot</c>
1963 jhhudso 1.81 </pre>
1964 zhen 1.16 <note>
1965 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1966     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1967     generally make changes to the files in <path>/etc/modules.d</path>.
1968     </note>
1969 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1970 zhen 1.6 use the bootdisk for the first reboot.
1971     then go back and install grub the way everyone else did the first
1972 drobbins 1.21 time. You are done -- congratulations!</impo>

1990     <title>Gentoo-Stats</title>
1991     <section>
1992     <body>
1993     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1994 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1995     us in set priorities our development. Installing it is completely optional, and it would be greatly
1996     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1997     </p>
1998 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1999 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
2000 peesh 1.99 to individually identify your system, nor will it be matched against an IP address or
2001 zhen 1.6 other personal information. Every precaution has been taken to assure your privacy in the
2002     development of this system. The following are the things that we are monitoring
2003 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
2004 zhen 1.6 </p>
2005 zhen 1.16 <ul>
2006     <li>installed packages and their version numbers</li>
2007     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
2008     <li>memory information (total available physical RAM, total available swap space)</li>
2009     <li>PCI cards and network controller chips</li>
2010     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
2011     </ul>
2012     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
2013 zhen 1.6 (just as it is to the developers).
2014     </p>
2015 zhen 1.16 <ul>
2016     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
2017 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
2018 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
2019     <li>The IP address your data transmission originates from will never be logged
2020     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
2021     </ul>
2022     <p>The installation is easy - just run the following commands:
2023 zhen 1.6 </p>
2024 jhhudso 1.81 <pre caption="Installing gentoo-stats">
2025 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
2026     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
2027 jhhudso 1.81 </pre>
2028 zhen 1.16 <p>The second command above will request a new system ID and enter it into
2029 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
2030     to see additional configuration options.
2031     </p>
2032 zhen 1.16 <p>After that, the program should be run on a regular schedule
2033 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
2034     </p>
2035 jhhudso 1.81 <pre caption="Updating gentoo-stats with cron">
2036     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
2037     </pre>
2038 zhen 1.16 <p>The <c>gentoo-stats</c> program is a simple perl script which can be
2039 jhhudso 1.75 viewed with your favorite pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
