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>
87    
88    
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 swift 1.131 <uri>ftp://ftp.ibiblio.org/pub/linux/distributions/gentoo/releases/1.4_rc4/x86/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 peesh 1.127 <note>The installation instructions in the LiveCD may not be the most up-to-date. Always refer to
112 klieber 1.129 <uri>http://www.gentoo.org/doc/en/gentoo-x86-install.xml</uri> for the most up-to-date
113 peesh 1.127 installation instructions.
114     </note>
115 jhhudso 1.75 <p>Now, let us quickly review the install process. First, we will download, burn
116     and boot a LiveCD. After getting a root prompt, we will create partitions, create
117 drobbins 1.21 our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
118     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
119 jhhudso 1.75 our system to stage3. Once our system is at stage3, we can configure it
120 seemant 1.78 (customize configuration files, install a boot loader, etc) and boot it and have a
121 drobbins 1.21 fully-functional Gentoo Linux system. Depending on what stage of the build
122 jhhudso 1.75 process you're starting from, here is what is required for installation: </p>

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>
488    
489     <p>
490     If your system uses SCSI drives, then your first hard drive will be:
491     </p>
492    
493     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
494     /dev/sda
495     </pre>
496    
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>
510    
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>
519    
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>
522    
523     <note>Alternate interfaces to the disk's partition table include <c>cfdisk</c>,
524 swift 1.123 <c>parted</c> and <c>partimage</c>. We recommend <c>fdisk</c> becuase it's
525     more powerfull and well known in the Unix/Linux world.</note>

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

618 drobbins 1.87 <p>Now that you've had your introduction to the way disk partitioning is
619 drobbins 1.86 done under Linux, it's time to walk you through the process of setting up disk
620     partitions for your Gentoo Linux installation. After we walk you through the
621     process of creating partitions on your disk, your partition configuration will
622     look like this: </p>
623    
624     <pre caption="The partition configuration that you will have after following these steps">

633    
634     Command (m for help):
635     </pre>
636    
637     <p>In our suggested "newbie" partition configuration, we have three partitions.
638     The first one (<c>/dev/hda1</c>) at the beginning of the disk is a small
639     partition called a boot partition. The boot partition's purpose is to hold all
640     the critical data related to booting -- GRUB boot loader information (if you
641     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
642     us a safe place to store everything related to booting Linux. During normal
643     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
644 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
645     likely end up being <c>/dev/sda1</c>.</p>
646 drobbins 1.86
647 drobbins 1.98 <p>It's recommended to have boot partitions (containing everything necessary for
648     the boot loader to work) at the beginning of the disk. While not necessarily
649     required anymore, it is a useful tradition from the days when the lilo boot
650     loader wasn't able to load kernels from filesystems that extended beyond disk
651     cylinder 1024.
652     </p>
653    
654 drobbins 1.86 <p>The second partition (<c>/dev/hda2</c>) is used to for swap space. The
655     kernel uses swap space as virtual memory when RAM becomes low. This partition,
656     relatively speaking, isn't very big either, typically somewhere around 512MB.
657 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
658     being called <c>/dev/sda2</c>. </p>
659 drobbins 1.86
660     <p>The third partition (<c>/dev/hda3</c>) is quite large and takes up the rest
661     of the disk. This partition is called our "root" partition and will be used to
662     store your main filesystem that houses Gentoo Linux itself. On a SCSI system,
663     this partition would likely end up being <c>/dev/sda3</c>.</p>
664    
665    
666     <p>Before we partition the disk, here's a quick technical overview of the
667     suggested partition and filesystem configuration to use when installing Gentoo
668     Linux:</p>

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

694     <ti>/dev/hda3</ti>
695     </tr>
696     </table>
697    
698     <p>OK, now to create the partitions as in the example and table above. First,
699 swift 1.95 enter fdisk by typing <c>fdisk /dev/hda</c> or <c>fdisk /dev/sda</c>,
700 drobbins 1.86 depending on whether you're using IDE or SCSI. Then, type <c>p</c> to view your
701     current partition configuration. Is there anything on the disk that you need
702     to keep? If so, <b>stop now</b>. If you continue with these directions, <b>all
703     existing data on your disk will be erased.</b></p>
704    
705     <impo>Following these instructions below will cause all prior data on your disk
706     to <b>be erased</b>! If there is anything on your drive, please be sure that it
707     is non-critical information that you don't mind losing. Also make sure that you
708     <b>have selected the correct drive</b> so that you don't mistakenly wipe data
709     from the wrong drive.</impo>
710    
711     <p>Now, it's time to delete any existing partitions. To do this, type <c>d</c>
712     and hit Enter. You will then be prompted for the partition number you would like
713     to delete. To delete a pre-existing <c>/dev/hda1</c>, you would type:</p>
714    
715     <pre caption="Deleting a partition">

722     saved. If you made a mistake and want to abort without saving your changes,
723     type <c>q</c> immediately and hit enter and your partition will not be
724     deleted.</p>
725     <p>Now, assuming that you do indeed want to wipe out all the partitions on your

838     <title>Creating filesystems</title>
839     <body>
840     <p>Now that the partitions have been created, it's time to set up filesystems on
841     the boot and root partitions so that they can be mounted and used to store data.
842     We will also configure the swap partition to serve as swap storage.
843     </p>
844    
845     <p>Gentoo Linux supports a variety of different types of filesystems; each type has
846     its strengths and weaknesses and its own set of performance characteristics. Currently,
847     we support the creation of ext2, ext3, XFS, JFS and ReiserFS filesystems.</p>
848    
849     <p>ext2 is the tried and true Linux filesystem but doesn't have metadata
850     journaling, which means that routine ext2 filesystem checks at startup time can
851     be quite time-consuming. There is now quite a selection of newer-generation
852     <i>journaled</i> filesystems that can be checked for consistency very quickly
853     and are thus generally preferred over their non-journaled counterparts.
854     Journaled filesystems prevent long delays when you boot your system and your
855     filesystem happens to be in an <i>inconsistent</i> state.</p>
856    
857     <p>ext3 is the journaled version of the ext2 filesystem, providing metadata
858     journaling for fast recovery in addition to other enhanced journaling modes
859     like full data and ordered data journaling. ext3 is a very good and reliable
860 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
861     Because it does not extensively employ the use of "trees" in its internal
862     design, it doesn't scale very well, meaning that it is not an ideal choice for
863     very large filesystems, or situations where you will be handling very large
864     files or large quantities of files in a single directory. But when used within
865     its design parameters, ext3 is an excellent filesystem.</p>
866 drobbins 1.86
867     <p>ReiserFS is a B*-tree based filesystem that has very good overall
868     performance and greatly outperforms both ext2 and ext3 when dealing with small
869     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
870     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
871     now rock-solid and highly recommended for use both as a general-purpose
872     filesystem and for extreme cases such as the creation of large filesystems, the
873     use of many small files, very large files, and directories containing tens of
874     thousands of files. ReiserFS is the filesystem we recommend by default for all
875     non-boot partitions.</p>
876    
877     <p>XFS is a filesystem with metadata journaling that is fully supported under
878     Gentoo Linux's <path>xfs-sources</path> kernel. It comes with a robust
879     feature-set and is optimized for scalability. We only recommend using this
880     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
881     a uninterruptible power supply. Because XFS aggressively caches in-transit data
882     in RAM, improperly designed programs (those that don't take proper precautions
883     when writing files to disk, and there are quite a few of them) can lose a good
884     deal of data if the system goes down unexpectedly.</p>
885    
886     <p>JFS is IBM's own high performance journaling filesystem. It has recently
887     become production-ready, and there hasn't been a sufficient track record to
888     comment either positively nor negatively on its general stability at this
889     point.</p>
890    
891     <p>If you're looking for the most rugged journaling filesystem, use ext3. If
892     you're looking for a good general-purpose high-performance filesystem with
893     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
894     refined and recommended for general use.</p>
895    
896     <!-- Corner case, confusing
897 drobbins 1.70 <p>But before creating filesystems, you may want to initialize the
898 jhhudso 1.81 beginning of your partition using <c>dd</c> if you are using a pre-existing partition that has been used before.
899 drobbins 1.70 This is particularly helpful when you're going to create a new XFS filesystem on a partition that previously contained
900     a ReiserFS filesystem. Doing this will ensure that your new filesystem
901 seemant 1.78 will not be mis-identified by Linux's filesystem auto-detection code.
902 drobbins 1.21 This can be done as follows:

907     </pre>
908     <warn>The command above will destroy all data from <path>/dev/hda3</path>.
909 zhware 1.43 Be careful and check twice which partition you specify for zeroing.

911     </warn>
912 drobbins 1.86 -->
913    
914     <p>Based on our example above, we will use the following commands to initialize
915     all our partitions for use:</p>
916    
917     <pre caption="Initializing our partitions (example)">
918     # mke2fs -j /dev/hda1
919     # mkswap /dev/hda2
920     # mkreiserfs /dev/hda3
921     </pre>
922    
923 drobbins 1.98 <p>We choose ext3 for our <c>/dev/hda1</c> boot partition because it is a
924     robust journaling filesystem supported by all major boot loaders. We used
925     <c>mkswap</c> for our <c>/dev/hda2 </c> swap partition -- the choice is obvious
926     here. And for our main root filesystem on <c>/dev/hda3</c> we choose ReiserFS,
927     since it is a solid journaling filesystem offering excellent performance. Now,
928     go ahead and initialize your partitions.</p>
929    
930     <p>For your reference, here are the various <c>mkfs</c>-like commands available
931     during the installation process:</p>
932 drobbins 1.86
933 drobbins 1.89 <p><c>mkswap</c> is the command that is used to initialize swap partitions:</p>

935 drobbins 1.1 # <c>mkswap /dev/hda2</c>
936 jhhudso 1.81 </pre>
937 drobbins 1.89 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems:</p>
938 jhhudso 1.81 <pre caption="Creating an ext2 Filesystem">
939 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
940 jhhudso 1.81 </pre>
941 drobbins 1.86 <p>If you would like to use ext3, you can create ext3 filesystems using
942 drobbins 1.89 <c>mke2fs -j</c>:</p>
943 drobbins 1.86 <pre caption="Creating an ext3 Filesystem">
944     # <c>mke2fs -j /dev/hda3</c>
945     </pre>
946     <note>You can find out more about using ext3 under Linux 2.4 at
947     <uri>http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html</uri>.</note>
948 drobbins 1.89 <p>To create ReiserFS filesystems, use the <c>mkreiserfs</c> command:</p>
949 drobbins 1.86 <pre caption="Creating a ReiserFS Filesystem">
950     # <c>mkreiserfs /dev/hda3</c>
951     </pre>
952 drobbins 1.89 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command:</p>
953 jhhudso 1.81 <pre caption="Creating a XFS Filesystem">
954 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
955 jhhudso 1.81 </pre>
956     <note>You may want to add a couple of additional flags to the
957     <c>mkfs.xfs</c> command: <c>-d agcount=3 -l size=32m</c>.
958     The <c>-d agcount=3</c> command will lower the number of allocation groups.
959     XFS will insist on using at least 1 allocation group per 4 GB of your
960     partition, so, for example, if you have a 20 GB partition you will need
961     a minimum agcount of 5. The <c>-l size=32m</c> command increases the
962     journal size to 32 Mb, increasing performance.</note>
963 drobbins 1.86
964 drobbins 1.89 <p>To create JFS filesystems, use the <c>mkfs.jfs</c> command:</p>

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

1021 drobbins 1.86 If you're using one of our bigger CDs like the "3stages" ISO, you will also

1139 drobbins 1.86
1140     <p>Now that you have a working copy of the Portage tree, it is time to
1141     customize the optimization and optional build-time settings to use on your
1142     Gentoo Linux system. Portage will use these settings when compiling any
1143     programs for you. To do this, edit the file <path>/etc/make.conf</path>. In
1144     this file, you should set your <c>USE</c> flags, which specify optional
1145     functionality that you would like to be built into packages if available;
1146     generally, the defaults (an <e>empty</e> or unset <c>USE</c> variable) are
1147     fine. More information on <c>USE</c> flags can be found <uri
1148     link="http://www.gentoo.org/doc/en/use-howto.xml">here</uri>. A complete list
1149     of current USE flags can be found <uri
1150     link="http://www.gentoo.org/dyn/use-index.xml">here</uri>. </p>
1151    
1152     <p>You also should set appropriate <c>CHOST</c>, <c>CFLAGS</c> and
1153     <c>CXXFLAGS</c> settings for the kind of system that you are creating
1154     (commented examples can be found further down in the file.) These settings
1155     will be used to tell the C and C++ compiler how to optimize the code that
1156     is generated on your system. It is common for users with Athlon XP processors
1157     to specify a "-march=athlon-xp" setting in their CFLAGS and CXXFLAGS settings
1158     so that all packages built will be optimized for the instruction set and
1159     performance characteristics of their CPU, for example. The <path>/etc/make.conf</path>
1160     file contains a general guide for the proper settings of CFLAGS and CXXFLAGS.</p>
1161 drobbins 1.70
1162 drobbins 1.86 <p>If necessary, you can also set proxy information here if you are behind a
1163     firewall. Use the following command to edit <path>/etc/make.conf</path> using <c>nano</c>,

1170 zhen 1.16 <note>
1171 jhhudso 1.75 People who need to substantially customize the build process should take a look at
1172 zhen 1.6 the <path>/etc/make.globals</path> file. This file comprises gentoo defaults and
1173 drobbins 1.70 should never be touched. If the defaults do not suffice, then new values should

1175     <comment>override</comment> the entries in <path>make.globals</path>. If you're
1176 jhhudso 1.75 interested in customizing USE settings, look in <path>/etc/make.profile/make.defaults</path>.
1177 zhen 1.16 If you want to turn off any USE settings found here, add an appropriate <c>USE=&quot;-foo&quot;</c>
1178 drobbins 1.86 in <path>/etc/make.conf</path> to turn off any <c>foo</c> USE setting enabled by default

1189 jhhudso 1.75 <p>The stage1 tarball is for complete customization and optimization. If you have picked this tarball,
1190 drobbins 1.86 you are most likely looking to have an uber-optimized and up-to-date system. Have fun, because optimization
1191 drobbins 1.70 is what Gentoo Linux is all about! Installing from a stage1 takes a lot of time, but the result
1192     is a system that has been optimized from the ground up for your specific machine and needs.
1193 zhen 1.18 </p>
1194 jhhudso 1.75 <p>Now, it is time to start the &quot;bootstrap&quot; process. This process takes about two hours on
1195 peesh 1.99 my 1200MHz AMD Athlon system.
1196 drobbins 1.86 During this time, the GNU C library, compiler suite and other key system programs will be built. Start the bootstrap
1197     as follows:</p>

1202 antifa 1.125 <p>The &quot;bootstrap&quot; process will now begin.</p>
1203     <note><c>bootstrap.sh</c> now supports the <c>--fetchonly</c> option. Dial-up users will find this especially handy. It will download all bootstrap related files in one go for later compilation. <c>bootstrap.sh -h</c> for more information.</note>
1204 zhen 1.16 <note>
1205 zhen 1.6 Portage by default uses <c>/var/tmp</c> during package building, often
1206     using several hundred megabytes of temporary storage. If you would like to
1207     change where Portage stores these temporary files, set a new PORTAGE_TMPDIR <e>before</e>
1208     starting the bootstrap process, as follows:

1263 drobbins 1.108
1264 drobbins 1.86 <p>The stage3 tarball provides a fully-functional basic Gentoo system, so no building is required.
1265     However, since the stage3 tarball is pre-built, it may be slightly out-of-date. If this is a concern
1266 drobbins 1.108 for you, you can automatically update your existing stage3 to contain the most up-to-date versions of all system packages
1267 drobbins 1.86 by performing the following steps. Note that this could take a long time if your stage3 is very old;
1268     otherwise, this process will generally be quick and will allow you to benefit from the very latest
1269     Gentoo updates and fixes.
1270     In any case, feel free to skip these

1437 zhen 1.6 Metalog flushes output to the disk in blocks, so messages aren't immediately recorded into
1438     the system logs. If you are trying to debug a daemon, this performance-enhancing behavior
1439     is less than helpful. When your Gentoo Linux system is up and running, you can send
1440     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
1441     <i>tail -f <path>/var/log/everything/current</path></i> will now work
1442     in real time, as expected),
1443     and a USR2 signal to turn buffering back on
1444 zhen 1.39 again. If you want to disable buffering permanently, you can change METALOG_OPTS="-B" to METALOG_OPTS="-B -s"
1445     in <path>/etc/conf.d/metalog</path>.

1695     Using our virtual package system, users are now able to choose between both GRUB and
1696     LILO as their bootloaders.
1697     </p>
1698     <p> Please keep in mind that having both bootloaders installed is not necessary.

1701 drobbins 1.69 <impo>If you are installing Gentoo Linux on a system with an NVIDIA nForce or nForce2 chipset
1702     with an integrated GeForce graphics card, you should use LILO and avoid GRUB. With on-board
1703 drobbins 1.70 video enabled, the low memory area of your RAM may be used as video RAM. Since GRUB also uses low
1704     memory at boot time, it may experience an "out of memory" condition. So, if you have an nForce
1705 drobbins 1.69 or potentially other board with on-board video, use LILO. Even if you're using off-board video
1706 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

1720 zhen 1.49 <title>Configuring GRUB</title>
1721 zhen 1.16 <body>
1722     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1723 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1724     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1725 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1726 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1727     cdrom players, burners, and that the same construct can be used with scsi drives.
1728     (Normally they get higher numbers than ide drives except when the bios is configured
1729     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1730 peesh 1.103 a burner on /dev/hdc, a second hard drive on /dev/hdd and no scsi harddrive,
1731 zhen 1.6 <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1732    
1733     It might sound tricky, and tricky it is indeed, but as we will see, grub
1734     offers a tab completion mechanism that comes handy for those of you having
1735     a lot of harddrives and partitions and who are a little lost in the
1736     grub numbering scheme. Having gotten the feel for that,
1737 jhhudso 1.75 it is time to install GRUB.
1738 zhen 1.6 </p>
1739 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1740 jhhudso 1.81 <pre caption="Installing GRUB">
1741 zhen 1.51 # <c>emerge grub</c>
1742 drobbins 1.1 # <c>grub</c>
1743 jhhudso 1.81 </pre>
1744 jhhudso 1.75 <p>You will be presented with the <c>grub&gt;</c> grub
1745 zhen 1.6 command-line prompt. Now, you need to type in the
1746     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1747     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1748     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1749     I want to type are:
1750     </p>

1759 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
1760     grub&gt; <c>setup (hd0,4)</c> <codenote>Where the boot record is installed, here it is /dev/hda5</codenote>

1763 swift 1.136
1764 jhhudso 1.75 <p>Here is how the two commands work. The first <c>root ( )</c> command tells GRUB
1765 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1766     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1767     </c> command tells GRUB where to install the
1768     boot record - it will be configured to look for its special files at the <c>root
1769     ( )</c> location that you specified. In my case, I want the boot record on the
1770     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1771     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1772     could install GRUB to the boot record of a particular partition. In that case,
1773 jhhudso 1.75 I would specify a particular partition rather than the entire disk. Once the GRUB
1774 zhen 1.6 boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.

1777     <note> The tab completion mechanism of grub can be used from within grub,
1778     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1779     be prompted with a list of the available devices (not only harddrives),
1780     hitting the TAB key having written <c> root (hd</c>, grub would print the
1781     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1782     would make grub print the list of partitions on the first harddrive.
1783    
1784     Checking the syntax of the grub location with completion should really help
1785     to make the right choice.

1789 zhen 1.6 Gentoo Linux is now
1790     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1791 jhhudso 1.75 we get a nice GRUB boot menu when the system reboots. Here is how to do it.
1792 zhen 1.6 </p>
1793 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1794 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1795     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1796 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:

1816 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1817 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel

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

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

1838 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add

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

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 peesh 1.128 <li><i>root=/dev/hda3</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

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 swift 1.136 blanket, and generally not a bad thing to do. If your hardware doesn't
1918     let you install a working bootloader from the chrooted environment,
1919     you may <e>need</e> to make a GRUB boot disk.
1920     If you are in this camp, make a GRUB boot disk, and when you reboot
1921     the first time you can install GRUB to the MBR. Make your bootdisks
1922     like this:

1927 jhhudso 1.81 </pre>
1928 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>

1949    
1950 zhen 1.6 safely unmount your partitions
1951     and reboot the system:

1963 zhen 1.16 <note>
1964 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create

1987     <body>
1988     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1989 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1990     us in set priorities our development. Installing it is completely optional, and it would be greatly
1991     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1992     </p>
1993 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1994 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1995 peesh 1.99 to individually identify your system, nor will it be matched against an IP address or
1996 zhen 1.6 other personal information. Every precaution has been taken to assure your privacy in the
1997     development of this system. The following are the things that we are monitoring
1998 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1999 zhen 1.6 </p>
2000 zhen 1.16 <ul>
2001     <li>installed packages and their version numbers</li>
2002     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
2003     <li>memory information (total available physical RAM, total available swap space)</li>
2004     <li>PCI cards and network controller chips</li>
2005     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
2006     </ul>
2007     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
2008 zhen 1.6 (just as it is to the developers).
2009     </p>
2010 zhen 1.16 <ul>
2011     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
2012 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
2013 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
2014     <li>The IP address your data transmission originates from will never be logged
2015     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
2016     </ul>
2017     <p>The installation is easy - just run the following commands:
2018 zhen 1.6 </p>
2019 jhhudso 1.81 <pre caption="Installing gentoo-stats">

2026     </p>
2027 zhen 1.16 <p>After that, the program should be run on a regular schedule
2028 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
