39 zhen 1.16 <abstract>These instructions step you through the process of installing Gentoo
40 jhhudso 1.74 Linux 1.4_rc3. The Gentoo Linux installation process supports various installation
41 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
42     scratch.

47     <title>About the Install</title>
48     <section>
49     <body>
50 zhen 1.26 <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
51 jhhudso 1.71 as many SCSI CD-ROM drives, assuming that your CD-ROM and BIOS both support booting.
52 drobbins 1.21 Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
53     kernel) as well as support for all SCSI devices (available as modules.) In
54     addition, we provide modules for literally every kind of network card that
55     Linux supports, as well as tools to allow you to configure your network and
56 jhhudso 1.75 establish outbound (as well as inbound) <c>ssh</c> connections and to download
57 drobbins 1.21 files. </p>
58 zhen 1.26 <p>To install from the build CD, you will need to have a 486+ processor and
59 drobbins 1.69 ideally at least 64 Megabytes of RAM. (Gentoo Linux has been successfully
60 drobbins 1.21 built with 64MB of RAM + 64MB of swap space, but the build process is awfully
61     slow under those conditions.)</p>
62 zhen 1.26 <p>Gentoo Linux can be installed using one of three &quot;stage&quot; tarball files. The
63 drobbins 1.21 one you choose depends on how much of the system you want to compile yourself.
64 jhhudso 1.75 The stage1 tarball is used when you want to bootstrap and build the entire
65 drobbins 1.21 system from scratch. The stage2 tarball is used for building the entire system
66 jhhudso 1.75 from a bootstrapped state. The stage3 tarball already contains a basic Gentoo Linux system.</p>
67 drobbins 1.70 <p><b>So, should you choose to start from a stage1, stage2, or stage3 tarball?</b>
68     Starting from a stage1 allows you to have total control over the optimization settings
69     and optional build-time functionality that is initially enabled on your system. This
70 jhhudso 1.75 makes stage1 installs good for power users who know what they are doing. Stage2 installs
71     allow you to skip the bootstrap process, and doing this is fine if you are happy with
72 drobbins 1.70 the optimization settings that we chose for your particular stage2 tarball. Choosing to
73     go with a stage3 allows for the fastest install of Gentoo Linux, but also means that
74 jhhudso 1.75 your base system will have the optimization settings that we chose for you. Since major
75     releases of Gentoo Linux have stage3's specifically optimized for various popular processors,
76     this may be sufficient for you. <b>If you're installing Gentoo Linux for the first time, consider
77 drobbins 1.70 using a stage3 tarball for installation.</b></p>
80 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
81 jhhudso 1.74 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc3/x86/</uri> .
82 drobbins 1.22 </p>
83 zhen 1.26 <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
84 jhhudso 1.75 using CD burning software. Currently, we have two types of LiveCDs. The first
85     carries the &quot;gentoo-basic&quot; label, and is approximately 40MB in size, contains only the stage 1 tarball and lives
86 drobbins 1.24 in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
87     allow for a initial quick download and contains a stage1 tarball that can be
88     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
89 seemant 1.78 <p>The second flavor of LiveCD we currently offer is labeled &quot;gentoo-3stages.&quot;
90 jhhudso 1.75 This CD is also found in <path>x86/livecd</path>. It
91 jhhudso 1.77 contains stage 1, 2 and 3 tarballs. Using this LiveCD, it will be possible
92 jhhudso 1.75 for you to install a fully-functional Gentoo Linux system very quickly.</p>
93 jhhudso 1.77 <p><b>What happened to i686, pentium3, athlon, athlon-mp stages, LiveCDs and GRP (Gentoo Reference Platform)?</b>
94 seemant 1.78 Gentoo 1.4_rc3 is meant to be a minimal release candidate only. 1.4_rc4 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>
95 jhhudso 1.77 </p>
96 drobbins 1.70 <impo>If you encounter a problem with any part of the install and wish to
97 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
98 jhhudso 1.75 needs to be sent upstream to the original software developers (eg the KDE team) the
99 drobbins 1.70 <e>Gentoo Linux developers</e> will take care of that for you.
100     </impo>
101 jhhudso 1.75 <p>Now, let us quickly review the install process. First, we will download, burn
102     and boot a LiveCD. After getting a root prompt, we will create partitions, create
103 drobbins 1.21 our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
104     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
105 jhhudso 1.75 our system to stage3. Once our system is at stage3, we can configure it
106 seemant 1.78 (customize configuration files, install a boot loader, etc) and boot it and have a
107 drobbins 1.21 fully-functional Gentoo Linux system. Depending on what stage of the build
108 jhhudso 1.75 process you're starting from, here is what is required for installation: </p>

131     <title>Booting</title>
132     <section>
133     <body>
134 jhhudso 1.75 <p>Start by booting the LiveCD. You should see a fancy boot screen
135 drobbins 1.21 with the Gentoo Linux logo on it. At this screen, you can hit Enter to begin the boot process,
136 drobbins 1.70 or boot the LiveCD with custom boot options by typing <c>gentoo opt1 opt2</c> and then hitting Enter. To see
137     a detailed description of available boot options, press F2 to view the help screen.</p>
139 jhhudso 1.75 <p> Once you hit Enter, you will be greeted with the standard kernel
140     booting output, kernel and initrd messages, followed by the normal Gentoo
141     Linux boot sequence. You will be automatically logged in as
142     &quot;<c>root</c>&quot; and the root password will be set to a random string
143     for security purposes. You should have a root (&quot;<c>#</c>&quot;) prompt
144 seemant 1.78 on the current console, and can also switch to other consoles by pressing
145 jhhudso 1.75 Alt-F2, Alt-F3 and Alt-F4. Get back to the one you started on by pressing
146     Alt-F1. At this point you should set the root password, type passwd and
147     follow the prompts.
148 zhen 1.6 </p>
149 zhen 1.26 <p>You've probably also noticed that above your <c>#</c> prompt is a bunch of help text
150 drobbins 1.70 that explains how to do things like configure your Linux networking and telling you where you can find
151 drobbins 1.21 the Gentoo Linux stage tarballs and packages on your CD.

378 zhen 1.16 <body>
379 drobbins 1.86 <p>
380     In this section, we'll take a good look at disk-oriented aspects of Gentoo Linux and Linux in general, including
381     Linux filesystems, partitions and block devices. Then, once you're familar with the ins and outs of disks and
382     filesystems, you'll be guided through the process of setting up partitions and filesystems for your Gentoo Linux
383     install.
384     </p>
385     <p>
386     To begin, I'll introduce "block devices". The most famous block device is
387     probably the one that represents the first IDE drive in a Linux system:
388     </p>
389     <pre caption="/dev/hda, the block device representing the primary master IDE drive in your system">
390     /dev/hda
391     </pre>
393     <p>
394     If your system uses SCSI drives, then your first hard drive will be:
395     </p>
397     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
398     /dev/sda
399     </pre>
401     <p>The block devices above represent an <i>abstract</i> interface to the disk.
402     User programs can use these block devices to interact with your disk without
403     worrying about whether your drivers are IDE, SCSI or something else. The
404     program can simply address the storage on the disk as a bunch of contiguous,
405     randomly-accessible 512-byte blocks. </p>
406     </body>
407     </section>
408     <section>
409     <title>Partitions and fdisk</title>
410     <body>
411     <p> Under Linux, we create filesystems by using a special command called
412     <c>mkfs</c> (or <c>mke2fs</c>, <c>mkreiserfs</c>, etc,) specifying a particular
413     block device as a command-line argument. </p>
415     <p> However, although it is theoretically possible to use a "whole disk" block
416     device (one that represents the <i>entire</i> disk) like <c>/dev/hda</c> or
417     <c>/dev/sda</c> to house a single filesystem, this is almost never done in
418     practice. Instead, full disk block devices are split up into smaller, more
419     manageable block devices called "partititons". Partitions are created using a
420     tool called <c>fdisk</c>, which is used to create and edit the partition table
421     that's stored on each disk. The partition table defines exactly how to split
422     up the full disk. </p>
424     <p> We can take a look at a disk's partition table by running <c>fdisk</c>,
425     specifying a block device that represents a full disk as an argument: </p>
427     <note>Alternate interfaces to the disk's partition table include <c>cfdisk</c>,
428     <c>parted</c> and <c>partimage</c></note>
430     <pre caption="Starting up fdisk">
431     # fdisk /dev/hda
432     </pre>

434     or

436     <pre caption="Starting up fdisk to look at the partition table on /dev/sda">
437     # fdisk /dev/sda
438     </pre>
440     <impo>
441     <b>Note that you should <i>not</i> save or make any changes to a disk's
442     partition table if any of its partitions contain filesystems that are in use or
443     contain important data. Doing so will generally cause data on the disk to be
444     lost.</b>
445     </impo>
447     <p>
448     Once in fdisk, you'll be greeted with a prompt that looks like this:

480     <p> This particular disk is configured to house seven Linux filesystems (each
481     with a corresponding partition listed as "Linux") as well as a swap partition
482     (listed as "Linux swap"). </p>
484     <p>
485     Notice the name of the corresponding partition block
486     devices on the left hand side, starting with <c>/dev/hda1</c> and going up to
487     <c>/dev/hda9</c>. In the early days of the PC, partitioning software only
488     allowed a maximum of four partitions (called "primary" partitions). This was
489     too limiting, so a workaround called an <i>extended partitioning</i> was
490     created. An extended partition is very similar to a primary partition, and
491     counts towards the primary partition limit of four. However, extended
492     partitions can hold any number of so-called <i>logical</i> partitions inside
493     them, providing an effective means of working around the four partition limit.
494     </p>
496     <p>
497     All partitions <c>hda5</c> and higher are logical partitions. The numbers 1
498     through 4 are reserved for primary or extended partitions. </p>
500     <p> So, In our example, <c>hda1</c> through <c>hda3</c> are primary partitions.
501     <c>hda4</c> is an extended partition that contains logical partitions
502 drobbins 1.87 <c>hda5</c> through <c>hda9</c>. You would never actually
503 drobbins 1.86 <i>use</i> <c>/dev/hda4</c> for storing any filesystems directly -- it simply
504     acts as a container for partitions <c>hda5</c> through <c>hda9</c>. </p>
506     <p> Also, notice that each partition has an "Id", also called a "partition
507     type". Whenever you create a new partition, you should ensure that the
508     partition type is set correctly. '83' is the correct partition type for
509     partitions that will be housing Linux filesystems, and '82' is the correct
510     partition type for Linux swap partitions. You set the partition type using the
511     <c>t</c> option in <c>fdisk</c>. The Linux kernel uses the partition type
512     setting to auto-detect fileystems and swap devices on the disk at boot-time.

517     <title>Using fdisk to set up partitions</title>
518     <body>
520 drobbins 1.87 <p>Now that you've had your introduction to the way disk partitioning is
521 drobbins 1.86 done under Linux, it's time to walk you through the process of setting up disk
522     partitions for your Gentoo Linux installation. After we walk you through the
523     process of creating partitions on your disk, your partition configuration will
524     look like this: </p>
526     <pre caption="The partition configuration that you will have after following these steps">
527     Disk /dev/hda: 30.0 GB, 30005821440 bytes
528     240 heads, 63 sectors/track, 3876 cylinders
529     Units = cylinders of 15120 * 512 = 7741440 bytes
531     Device Boot Start End Blocks Id System
532     /dev/hda1 * 1 14 105808+ 83 Linux
533     /dev/hda2 15 81 506520 82 Linux swap
534     /dev/hda3 82 3876 28690200 83 Linux
536     Command (m for help):
537     </pre>
539     <p>In our suggested "newbie" partition configuration, we have three partitions.
540     The first one (<c>/dev/hda1</c>) at the beginning of the disk is a small
541     partition called a boot partition. The boot partition's purpose is to hold all
542     the critical data related to booting -- GRUB boot loader information (if you
543     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
544     us a safe place to store everything related to booting Linux. During normal
545     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
546 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
547     likely end up being <c>/dev/sda1</c>.</p>
548 drobbins 1.86
549     <p>The second partition (<c>/dev/hda2</c>) is used to for swap space. The
550     kernel uses swap space as virtual memory when RAM becomes low. This partition,
551     relatively speaking, isn't very big either, typically somewhere around 512MB.
552 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
553     being called <c>/dev/sda2</c>. </p>
554 drobbins 1.86
555     <p>The third partition (<c>/dev/hda3</c>) is quite large and takes up the rest
556     of the disk. This partition is called our "root" partition and will be used to
557     store your main filesystem that houses Gentoo Linux itself. On a SCSI system,
558     this partition would likely end up being <c>/dev/sda3</c>.</p>
561     <p>Before we partition the disk, here's a quick technical overview of the
562     suggested partition and filesystem configuration to use when installing Gentoo
563     Linux:</p>
565     <table>
566     <tr>
567     <th>Partition</th>
568     <th>Size</th>
569     <th>Type</th>
570     <th>example device</th>
571     </tr>
572     <tr>
573     <ti>boot partition, containing kernel(s) and boot information</ti>
574     <ti>100 Megabytes</ti>
575     <ti>ext2/3 highly recommended (easiest); if ReiserFS then mount with <c>-o notail</c></ti>

577     </tr>
578     <tr>
579     <ti>swap partition (no longer a 128 Megabyte limit, now 2GB)</ti>
580     <ti>Generally, configure a swap area that is between one to two times the size of the physical RAM
581     in your system.</ti>
582     <ti>Linux swap</ti>

585     <tr>
586     <ti>root partition, containing main filesystem (/usr, /home, etc)</ti>
587     <ti>&gt;=1.5 Gigabytes</ti>
588     <ti>ReiserFS, ext3 recommended; ext2 ok</ti>
589     <ti>/dev/hda3</ti>
590     </tr>
591     </table>
593     <p>OK, now to create the partitions as in the example and table above. First,
594     enter fdisk by typing <c>fdisk /dev/hda1</c> or <c>fdisk /dev/sda1</c>,
595     depending on whether you're using IDE or SCSI. Then, type <c>p</c> to view your
596     current partition configuration. Is there anything on the disk that you need
597     to keep? If so, <b>stop now</b>. If you continue with these directions, <b>all
598     existing data on your disk will be erased.</b></p>
600     <impo>Following these instructions below will cause all prior data on your disk
601     to <b>be erased</b>! If there is anything on your drive, please be sure that it
602     is non-critical information that you don't mind losing. Also make sure that you
603     <b>have selected the correct drive</b> so that you don't mistakenly wipe data
604     from the wrong drive.</impo>
606     <p>Now, it's time to delete any existing partitions. To do this, type <c>d</c>
607     and hit Enter. You will then be prompted for the partition number you would like
608     to delete. To delete a pre-existing <c>/dev/hda1</c>, you would type:</p>
610     <pre caption="Deleting a partition">
611     Command (m for help): d
612     Partition number (1-4): 1
613     </pre>
614 zhen 1.54
615 drobbins 1.86 <p>The partition has been scheduled for deletion. It will no longer show up if
616     you type <c>p</c>, but it will not be erased until your changes have been
617     saved. If you made a mistake and want to abort without saving your changes,
618     type <c>q</c> immediately and hit enter and your partition will not be
619     deleted.</p>
620     <!-- NOTE: THis is not sufficient documentation to cover ATA Raid and I just
621     find it confusing, so I'm commenting it out (drobbins)
622     <note>If you are using RAID your partitions will be a little different. You
623 jhhudso 1.75 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X are
624 drobbins 1.70 the arrays you have made, so if you only have made 1 array, then it will be
625     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
626 drobbins 1.86 -->
627     <p>Now, assuming that you do indeed want to wipe out all the partitions on your
628     system, repeatedly type <c>p</c> to print out a partition listing and then type
629     <c>d</c> and the number of the partition to delete it. Eventually, you'll end up
630     with a partition table with nothing in it:</p>
632     <pre caption="An empty partition table">
633     Disk /dev/hda: 30.0 GB, 30005821440 bytes

637     Device Boot Start End Blocks Id System
639     Command (m for help):

642     <p>Now that the in-memory partition table is empty, we're ready to create a
643     boot partition. To do this, type <c>n</c> to create a new partition, then
644     <c>p</c> to tell fdisk you want a primary partition. Then type <c>1</c> to
645     create the first primary partition. When prompted for the first cylinder, hit
646     enter. When prompted for the last cylinder, type <c>+100M</c> to create a
647     partition 100MB in size. You can see output from these steps below:</p>

671     /dev/hda1 1 14 105808+ 83 Linux
672     </pre>
674     <p>Next, let's create the swap partition. To do this, type <c>n</c> to create a
675     new partition, then <c>p</c> to tell fdisk that you want a primary partition. Then
676     type <c>2</c> to create the second primary partition, <c>/dev/hda2</c> in our case.
677     When prompted for the first cylinder, hit enter. When prompted for the last cylinder,
678     type <c>+512M</c> to create a partition 512MB in size. After you've done this, type
679     <c>t</c> to set the partition type, and then type in <c>82</c> to set the partition
680     type to "Linux Swap". After completing these steps, typing <c>p</c> should display
681     a partition table that looks similar to this:</p>

692     /dev/hda2 15 81 506520 82 Linux swap
693     </pre>
695     <p>Finally, let's create the root partition. To do this, type <c>n</c> to
696     create a new partition, then <c>p</c> to tell fdisk that you want a primary
697     partition. Then type <c>3</c> to create the second primary partition,
698     <c>/dev/hda3</c> in our case. When prompted for the first cylinder, hit enter.
699     When prompted for the last cylinder, hit enter to create a partition that takes
700     up the rest of the remaining space on your disk. After completing these steps,
701     typing <c>p</c> should display a partition table that looks similar to
702     this:</p>
704     <pre caption="Our root partition has been created">

715     </pre>
717     <p>
718     Finally, we need to set the "bootable" flag on our boot partition and then write
719     our changes to disk. To tag <c>/dev/hda1</c> as a "bootable" partition, type
720     <c>a</c> at the menu and then type in <c>1</c> for the partition number. If you
721     type <c>p</c> now, you'll now see that <c>/dev/hda1</c> has a <c>*</c> in the "Boot"
722     column. Now, let's write our changes to disk. To do this, type <c>w</c> and hit
723     enter. Your disk partitions are now properly configured for a Gentoo Linux
724     install.
725     </p>
727     <note>If <c>fdisk</c> or <c>cfdisk</c> instruct you to do so, please reboot to

732     <title>Creating filesystems</title>
733     <body>
734     <p>Now that the partitions have been created, it's time to set up filesystems on
735     the boot and root partitions so that they can be mounted and used to store data.
736     We will also configure the swap partition to serve as swap storage.
737     </p>
739     <p>Gentoo Linux supports a variety of different types of filesystems; each type has
740     its strengths and weaknesses and its own set of performance characteristics. Currently,
741     we support the creation of ext2, ext3, XFS, JFS and ReiserFS filesystems.</p>
743     <p>ext2 is the tried and true Linux filesystem but doesn't have metadata
744     journaling, which means that routine ext2 filesystem checks at startup time can
745     be quite time-consuming. There is now quite a selection of newer-generation
746     <i>journaled</i> filesystems that can be checked for consistency very quickly
747     and are thus generally preferred over their non-journaled counterparts.
748     Journaled filesystems prevent long delays when you boot your system and your
749     filesystem happens to be in an <i>inconsistent</i> state.</p>
751     <p>ext3 is the journaled version of the ext2 filesystem, providing metadata
752     journaling for fast recovery in addition to other enhanced journaling modes
753     like full data and ordered data journaling. ext3 is a very good and reliable
754 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
755     Because it does not extensively employ the use of "trees" in its internal
756     design, it doesn't scale very well, meaning that it is not an ideal choice for
757     very large filesystems, or situations where you will be handling very large
758     files or large quantities of files in a single directory. But when used within
759     its design parameters, ext3 is an excellent filesystem.</p>
760 drobbins 1.86
761     <p>ReiserFS is a B*-tree based filesystem that has very good overall
762     performance and greatly outperforms both ext2 and ext3 when dealing with small
763     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
764     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
765     now rock-solid and highly recommended for use both as a general-purpose
766     filesystem and for extreme cases such as the creation of large filesystems, the
767     use of many small files, very large files, and directories containing tens of
768     thousands of files. ReiserFS is the filesystem we recommend by default for all
769     non-boot partitions.</p>
771     <p>XFS is a filesystem with metadata journaling that is fully supported under
772     Gentoo Linux's <path>xfs-sources</path> kernel. It comes with a robust
773     feature-set and is optimized for scalability. We only recommend using this
774     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
775     a uninterruptible power supply. Because XFS aggressively caches in-transit data
776     in RAM, improperly designed programs (those that don't take proper precautions
777     when writing files to disk, and there are quite a few of them) can lose a good
778     deal of data if the system goes down unexpectedly.</p>
780     <p>JFS is IBM's own high performance journaling filesystem. It has recently
781     become production-ready, and there hasn't been a sufficient track record to
782     comment either positively nor negatively on its general stability at this
783     point.</p>
785     <p>If you're looking for the most rugged journaling filesystem, use ext3. If
786     you're looking for a good general-purpose high-performance filesystem with
787     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
788     refined and recommended for general use.</p>

791 drobbins 1.70 <p>But before creating filesystems, you may want to initialize the
792 jhhudso 1.81 beginning of your partition using <c>dd</c> if you are using a pre-existing partition that has been used before.
793 drobbins 1.70 This is particularly helpful when you're going to create a new XFS filesystem on a partition that previously contained
794     a ReiserFS filesystem. Doing this will ensure that your new filesystem
795 seemant 1.78 will not be mis-identified by Linux's filesystem auto-detection code.
796 drobbins 1.21 This can be done as follows:

815     </pre>
817     <p>We choose ext3 for our <c>/dev/hda1</c> boot partition because it is a robust journaling

820     <c>/dev/hda3</c> we choose ReiserFS, since it is a solid journaling filesystem offering excellent

1010 drobbins 1.86
1011     <p>Now that you have a working copy of the Portage tree, it is time to
1012     customize the optimization and optional build-time settings to use on your
1013     Gentoo Linux system. Portage will use these settings when compiling any
1014     programs for you. To do this, edit the file <path>/etc/make.conf</path>. In
1015     this file, you should set your <c>USE</c> flags, which specify optional
1016     functionality that you would like to be built into packages if available;
1017     generally, the defaults (an <e>empty</e> or unset <c>USE</c> variable) are
1018     fine. More information on <c>USE</c> flags can be found <uri
1019     link="http://www.gentoo.org/doc/en/use-howto.xml">here</uri>. A complete list
1020     of current USE flags can be found <uri
1021     link="http://www.gentoo.org/dyn/use-index.xml">here</uri>. </p>
1023     <p>You also should set appropriate <c>CHOST</c>, <c>CFLAGS</c> and
1024     <c>CXXFLAGS</c> settings for the kind of system that you are creating
1025     (commented examples can be found further down in the file.) These settings
1026     will be used to tell the C and C++ compiler how to optimize the code that
1027     is generated on your system. It is common for users with Athlon XP processors
1028     to specify a "-march=athlon-xp" setting in their CFLAGS and CXXFLAGS settings
1029     so that all packages built will be optimized for the instruction set and
1030     performance characteristics of their CPU, for example. The <path>/etc/make.conf</path>
1031     file contains a general guide for the proper settings of CFLAGS and CXXFLAGS.</p>

1132     However, since the stage3 tarball is pre-built, it may be slightly out-of-date. If this is a concern
1133     for you, you can update your stage3 to contain the most up-to-date versions of all system packages
1134     by performing the following steps. Note that this could take a long time if your stage3 is very old;
1135     otherwise, this process will generally be quick and will allow you to benefit from the very latest
1136     Gentoo updates and fixes.
1137     In any case, feel free to skip these
1138     steps and proceed to the next section if you like.

1275 zhen 1.16 <p>If you are using hardware RAID you will need to enable a couple more options in the kernel:
1276 zhen 1.6 For Highpoint RAID controllers select hpt366 chipset support, support for IDE RAID controllers and Highpoint
1277     370 software RAID.For Promise RAID controllers select PROMISE PDC202{46|62|65|67|68|69|70} support,
1278     support for IDE RAID
1279     controllers and Support Promise software RAID (Fasttrak(tm))
1280     </p>
1281 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
1282 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
1283 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
1284     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but
1285     are not definitely needed, neither does the &quot;PPP over Ethernet&quot; option,
1286 zhen 1.6 that might only be used by <i>rp-pppoe</i> when configured to do kernel mode PPPoE.
1287     </p>
1288 zhen 1.16 <p>If you have an IDE cd burner, then you need to enable SCSI emulation in the
1289     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA and ATAPI Block
1290     devices&quot; ---&gt; &quot;SCSI emulation support&quot; (I usually make it a module), then
1291     under &quot;SCSI support&quot; enable &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and
1292     &quot;SCSI generic support&quot; (again, I usually compile them as modules). If you
1293     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
1294     &gt;&gt; /etc/modules.autoload</c> to have them automatically added at boot time.
1295 zhen 1.6 </p>
1296 zhen 1.16 <note>
1297 zhen 1.6 For those who prefer it,
1298     it is now possible to install Gentoo Linux with a 2.2 kernel.
1299 drobbins 1.21 However, doing this comes at a price:
1300 zhen 1.6 you will lose many of the nifty features that
1301     are new to the 2.4 series kernels (such as XFS and tmpfs
1302     filesystems, iptables, and more), although the 2.2 kernel sources can be
1303 drobbins 1.21 patched with ReiserFS and devfs support.
1304     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
1305 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
1306     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
1307 peesh 1.85 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
1308     that a ramdisk is mounted for the boot scripts instead of tmpfs. If you choose not to use devfs, then
1309 zhen 1.6 <e>gentoo=notmpfs,nodevfs</e> should be used instead.
1310     </note>
1311 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
1312 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
1313     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
1314     to gravitate away from sysklogd (not very good performance) and towards the
1315     newer alternatives.
1316     If in doubt, you may want to try metalog, since it seems to be quite popular.
1317     To merge your logger of choice, type <e>one</e> of the next four lines:

1338 zhen 1.16 <impo>
1339 zhen 1.6 Metalog flushes output to the disk in blocks, so messages aren't immediately recorded into
1340     the system logs. If you are trying to debug a daemon, this performance-enhancing behavior
1341     is less than helpful. When your Gentoo Linux system is up and running, you can send
1342     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
1343     <i>tail -f <path>/var/log/everything/current</path></i> will now work
1344     in real time, as expected),
1345     and a USR2 signal to turn buffering back on
1346 zhen 1.39 again. If you want to disable buffering permanently, you can change METALOG_OPTS="-B" to METALOG_OPTS="-B -s"

1562     <p> In the spirit of Gentoo, users now have more than one bootloader to choose from.
1563     Using our virtual package system, users are now able to choose between both GRUB and
1564     LILO as their bootloaders.
1565     </p>
1566     <p> Please keep in mind that having both bootloaders installed is not necessary.
1567 jhhudso 1.75 In fact, it can be a hindrance, so please only choose one.
1568 zhen 1.49 </p>
1569 drobbins 1.69 <impo>If you are installing Gentoo Linux on a system with an NVIDIA nForce or nForce2 chipset
1570     with an integrated GeForce graphics card, you should use LILO and avoid GRUB. With on-board
1571 drobbins 1.70 video enabled, the low memory area of your RAM may be used as video RAM. Since GRUB also uses low
1572     memory at boot time, it may experience an "out of memory" condition. So, if you have an nForce
1573 drobbins 1.69 or potentially other board with on-board video, use LILO. Even if you're using off-board video
1574 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
1575 drobbins 1.69 pinch, wouldn't it? :)</impo>

1580 zhen 1.49 <title>Configuring GRUB</title>
1581 zhen 1.16 <body>
1582     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1583 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1584     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1585 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1586 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1587     cdrom players, burners, and that the same construct can be used with scsi drives.
1588     (Normally they get higher numbers than ide drives except when the bios is configured
1589     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1590     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1591     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1593     It might sound tricky, and tricky it is indeed, but as we will see, grub
1594     offers a tab completion mechanism that comes handy for those of you having
1595     a lot of harddrives and partitions and who are a little lost in the
1596     grub numbering scheme. Having gotten the feel for that,
1597 jhhudso 1.75 it is time to install GRUB.
1598 zhen 1.6 </p>
1599 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1600 jhhudso 1.81 <pre caption="Installing GRUB">
1601 zhen 1.51 # <c>emerge grub</c>
1602 drobbins 1.1 # <c>grub</c>
1603 jhhudso 1.81 </pre>
1604 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1605 zhen 1.6 this time.
1606     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1607     grub setup for RAID controllers
1608     </impo>
1609 jhhudso 1.75 <p>You will be presented with the <c>grub&gt;</c> grub
1610 zhen 1.6 command-line prompt. Now, you need to type in the
1611     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1612     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1613     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1614     I want to type are:
1615     </p>
1616 zhen 1.68
1617 jhhudso 1.81 <pre caption="GRUB on the MBR">
1618 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>

1620 jhhudso 1.81 </pre>
1621 zhen 1.68
1622 jhhudso 1.81 <pre caption="GRUB not on the MBR">
1623 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
1624 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
1625     grub&gt; <c>setup (hd0,4)</c> <codenote>Where the boot record is installed, here it is /dev/hda5</codenote>
1626 drobbins 1.1 grub&gt; <c>quit</c>
1627 jhhudso 1.81 </pre>
1628 zhen 1.68
1629 jhhudso 1.75 <p>Here is how the two commands work. The first <c>root ( )</c> command tells GRUB
1630 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1631     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1632     </c> command tells GRUB where to install the
1633     boot record - it will be configured to look for its special files at the <c>root
1634     ( )</c> location that you specified. In my case, I want the boot record on the
1635     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1636     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1637     could install GRUB to the boot record of a particular partition. In that case,
1638 jhhudso 1.75 I would specify a particular partition rather than the entire disk. Once the GRUB
1639 zhen 1.6 boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1640 zhen 1.52 </p>
1641 zhen 1.6
1642     <note> The tab completion mechanism of grub can be used from within grub,
1643     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1644     be prompted with a list of the available devices (not only harddrives),
1645     hitting the TAB key having written <c> root (hd</c>, grub would print the
1646     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1647     would make grub print the list of partitions on the first harddrive.
1649     Checking the syntax of the grub location with completion should really help
1650     to make the right choice.
1651     </note>
1653 zhen 1.52 <p>
1654 zhen 1.6 Gentoo Linux is now
1655     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1656 jhhudso 1.75 we get a nice GRUB boot menu when the system reboots. Here is how to do it.
1657 zhen 1.6 </p>
1658 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1659 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1660     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1661 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:

1683 zhen 1.6 (hd0,0) should be written without any spaces inside the parentheses.
1684     </note>
1685 zhen 1.16 <impo>
1686 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1687 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1688     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1689 zhen 1.6 </impo>
1690 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1691 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1692     and shows you how to use GRUB to boot a bootable Windows partition.
1693     </p>
1694 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1695 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1696     your root filesystem. <path>(hd0,5)</path> contains the NT boot

1698 zhware 1.9 </note>
1699 zhen 1.16 <note>
1700 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>.
1701 zhen 1.6 </note>
1702 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1703 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1704     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1705     turn off devfs by default (not recommended unless you know what you're doing) by
1706     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1707     </p>
1708 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1709 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1710     devfs is enabled by default.

1715     <title>Configuring LILO</title>
1716 zhen 1.16 <body>
1717 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1718 jhhudso 1.75 LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here is how to install
1719 drobbins 1.21 LILO if you would like to use it instead of GRUB:
1720 zhen 1.16 </p>
1721     <p>The first step is to emerge LILO:

1745 jhhudso 1.81 </pre>
1746 zhen 1.52 <ul>
1747 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>
1748     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1749     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1750     In normal use, this should not be altered. If the install line is missing, LILO will
1751     assume a default of /boot/boot.b as the file to be used. </li>
1752 zhen 1.83 <li>The existence of <i>prompt</i> tells LILO to display the classic <i>lilo:</i> prompt at bootup.
1753 zhen 1.16 While it is not recommended that you remove the prompt line, if you do remove it, you can still
1754     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1755     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1756     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1757     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1758     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1759     your system in an unbootable state. </li>
1760     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1761     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1762     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1763     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1764     it is also the name referred to by the default line. </li>
1765     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1766     altered during the boot process. </li>
1767     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1768 zhen 1.52 </ul>
1769 zhen 1.16 <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information

1785 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1786 zhen 1.16 time you install any Linux distribution. This is a security
1787 drobbins 1.21 blanket, and generally not a bad thing to do. If you are using some kinds of hardware RAID, you may <e>need</e> make a GRUB boot
1788     disk. With these types of hardware RAID,
1789     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1790     make a GRUB
1791     boot disk, and when you reboot the first time you can install GRUB
1792 zhen 1.6 to the MBR. Make your

1828 jhhudso 1.75 <p>Now, Gentoo Linux is installed. The only remaining step is to update necessary configuration files, exit the chrooted shell,
1830 zhen 1.6 safely unmount your partitions
1831     and reboot the system:
1832     </p>
1833 jhhudso 1.81 <pre caption="Rebooting the System">
1834 drobbins 1.1 # <c>etc-update</c>
1835     # <c>exit</c>
1836 jhhudso 1.81 <comment>(This exits the chrooted shell; you can also type <c>^D</c>)</comment>
1837 drobbins 1.1 # <c>cd / </c>
1838     # <c>umount /mnt/gentoo/boot</c>
1839     # <c>umount /mnt/gentoo/proc</c>
1840     # <c>umount /mnt/gentoo</c>
1841     # <c>reboot</c>
1842 jhhudso 1.81 </pre>
1843 zhen 1.16 <note>
1844 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1845     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1846     generally make changes to the files in <path>/etc/modules.d</path>.
1847     </note>
1848 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1849 zhen 1.6 use the bootdisk for the first reboot.
1850     then go back and install grub the way everyone else did the first
1851 drobbins 1.21 time. You are done -- congratulations!</impo>
1852 zhen 1.16 <p>If you have any questions or would like to get involved with Gentoo Linux development,
1853 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1854 seo 1.84 (more information on our <uri link="http://www.gentoo.org/main/en/lists.xml">mailing lists</uri> page).
1855 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>
1856     that will
1857     help you to continue configuring your new Gentoo Linux system, and a useful
1858     <uri link="http://www.gentoo.org/doc/en/portage-user.xml">Portage user guide</uri>
1859     to help familiarize you with Portage basics. You can find the rest of the Gentoo Documentation
1860 zhen 1.16 <uri link="http://www.gentoo.org/main/en/docs.xml">here</uri>. If you have any other questions
1861 zhen 1.10 involving installation or anything for that matter, please check the Gentoo Linux

1869     <title>Gentoo-Stats</title>
1870     <section>
1871     <body>
1872     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1873 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1874     us in set priorities our development. Installing it is completely optional, and it would be greatly
1875     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1876     </p>
1877 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1878 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1879     to individually identify your system, nor will it be mached against an IP address or
1880     other personal information. Every precaution has been taken to assure your privacy in the
1881     development of this system. The following are the things that we are monitoring
1882 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1883 zhen 1.6 </p>
1884 zhen 1.16 <ul>
1885     <li>installed packages and their version numbers</li>
1886     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1887     <li>memory information (total available physical RAM, total available swap space)</li>
1888     <li>PCI cards and network controller chips</li>
1889     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1890     </ul>
1891     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1892 zhen 1.6 (just as it is to the developers).
1893     </p>
1894 zhen 1.16 <ul>
1895     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1896 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1897 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1898     <li>The IP address your data transmission originates from will never be logged
1899     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1900     </ul>
1901     <p>The installation is easy - just run the following commands:
1902 zhen 1.6 </p>
1903 jhhudso 1.81 <pre caption="Installing gentoo-stats">
1904 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1905     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1906 jhhudso 1.81 </pre>
1907 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1908 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1909     to see additional configuration options.
1910     </p>
1911 zhen 1.16 <p>After that, the program should be run on a regular schedule
1912 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1913     </p>
1914 jhhudso 1.81 <pre caption="Updating gentoo-stats with cron">
1915     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1916     </pre>
1917 zhen 1.16 <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1918 jhhudso 1.75 viewed with your favorite pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
