27     <abstract>These instructions step you through the process of installing Gentoo
28 drobbins 1.21 Linux 1.4_rc2. The Gentoo Linux installation process supports various installation
29 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
30     scratch.

35     <title>About the Install</title>
36     <section>
37     <body>
38 zhen 1.26 <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
39 drobbins 1.21 as many SCSI CD-ROM, assuming that your CD-ROM and BIOS both support booting.
40     Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
41     kernel) as well as support for all SCSI devices (available as modules.) In
42     addition, we provide modules for literally every kind of network card that
43     Linux supports, as well as tools to allow you to configure your network and
44     establish outbound (as well as inbound) <c>ssh</c> connections and download
45     files. </p>
46 zhen 1.26 <p>To install from the build CD, you will need to have a 486+ processor and
47 drobbins 1.21 ideally at least 64 Megabytes of RAM. (Gentoo linux has been successfully
48     built with 64MB of RAM + 64MB of swap space, but the build process is awfully
49     slow under those conditions.)</p>
50 zhen 1.26 <p>Gentoo Linux can be installed using one of three &quot;stage&quot; tarball files. The
51 drobbins 1.21 one you choose depends on how much of the system you want to compile yourself.
52     The stage1 tarball is used when one wants to bootstrap and build the entire
53     system from scratch. The stage2 tarball is used for building the entire system
54     from scratch, except for the bootstrap part which is already performed for you.
55     And the stage3 tarball already contains a basic Gentoo Linux system that has
56     been optimized for your system.</p>
57 zhen 1.26 <p> So, how does one beging the install process? First, you'll want to decide
58 drobbins 1.21 which one of our LiveCD ISO images to grab from
59 drobbins 1.23 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc2/x86/</uri>.
60 drobbins 1.22 In this directory, you'll see several subdirectories such as <c>athlon</c>
61 drobbins 1.24 for each of our various architecture-specific builds. Here's a low-down on
62     each arch directory and what it contains:</p>

94     <ti>Stage 2 and 3 tarballs, GRP packages and liveCD for Intel Pentium III and Pentium 4 CPUs</ti>
95     </tr>
96     </table>
97     <p>Inside each of these directories,
98 drobbins 1.22 you'll find a <path>livecd/</path> directory that contains LiveCDs. While these LiveCDs
99     will boot on any architecture, the install-related tarballs are optimized for a particular
100 zhen 1.26 CPU type and will not work on all systems, except for the &quot;gentoo-basic&quot; LiveCD in the <path>x86</path>
101 drobbins 1.24 directory which can be used to install on anything.
102 drobbins 1.22 </p>
103 zhen 1.26 <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
104 drobbins 1.24 using CD burning software. Currently, we have two types of LiveCDs. The first
105 zhen 1.26 carries the &quot;gentoo-basic&quot; label, and is approximately 40MB in size and lives
106 drobbins 1.24 in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
107     allow for a initial quick download and contains a stage1 tarball that can be
108     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
109 zhen 1.26 <p>The second flavor of LiveCD we currently offer is labelled &quot;livecd-grp.&quot;
110 drobbins 1.24 These CDs (found in their respective <path>arch/livecd</path> directories)
111     contain stage1, 2 and 3 tarballs, and also contain a set of GRP packages
112     optimized for a specific architecture. Using these LiveCDs, it will be possible
113     for you to install a fully-functional Gentoo Linux system very quickly. The
114     downside is that these ISO images are large -- around 600MB -- so they can take
115     a while to download.</p>
116 zhen 1.26 <info>If for some reason your install gets interrupted at some point, you can
117 drobbins 1.24 reboot and restart. For example, if you have partitioned, installed the stageX
118     tarball, and are ready to chroot, you can restart the install if necessary.
119     Just re-boot with the LiveCD, then mount your drives/partitions to
120     <path>/mnt</path> as normal. Basically, you can do this at about any point
121     during the install, just not before partitioning for obvious reasons. </info>
122 zhen 1.26 <warn>If you encounter a problem with any part of the install and wish to
123 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
124     needs to be moved upstream to the package maintainers (ie KDE) the
125     <e>developers</e> will take care of that. </warn>
126 zhen 1.26 <p>Now, let's quickly review the install process. First, we'll download, burn
127 drobbins 1.21 and boot a LiveCD. After getting a root prompt, we'll create partitions, create
128     our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
129     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
130     our systems to stage3. Once our systems are at stage3, we can configure them
131     (tweaking config files, installing a bootloader, etc) and boot them and have a
132     fully-functional Gentoo Linux system. Depending on what stage of the build
133     process you're starting from, here's what's required for installation: </p>

156     <title>Booting</title>
157     <section>
158     <body>
159 drobbins 1.21 <p>Start by booting the LiveCD. If detected properly, you should see a fancy boot screen
160     with the Gentoo Linux logo on it. At this screen, you can hit Enter to begin the boot process,
161     hit F2 for help, or pass kernel boot options by typing <c>gentoo opt1 opt2</c>, etc.
162     Once you hit Enter, you'll be
163 zhen 1.6 greeted with a lot of text output
164     followed by the normal Gentoo Linux boot sequence.
165 drobbins 1.21 You will be automatically logged in as &quot;root&quot; and the root password will be
166     set to a random string for security purposes.
167 zhen 1.16 You should have a root (&quot;<c>#</c>&quot;) prompt on the current
168 drobbins 1.21 console, and can also open new root consoles by pressing Alt-F2, Alt-F3 and Alt-F4.
169     Get back to the one you started on by pressing (you guessed it) Alt-F1.
170 zhen 1.6 </p>
171 zhen 1.26 <p>You've probably also noticed that above your <c>#</c> prompt is a bunch of help text
172 drobbins 1.21 explaining how to do things like configure your network devices and where you can find
173     the Gentoo Linux stage tarballs and packages on your CD.

181     <body>
182     <p>If the PCI autodetection missed some of your hardware, you
183 zhen 1.6 will have to load the appropriate modules manually.
184     To view a list of all available network card modules, type <c>ls
185     /lib/modules/*/kernel/drivers/net/*</c>. To load a particular module,
186     type:

192 zhen 1.16 <p>Now, if you want to be able to access any SCSI hardware that wasn't detected
193 drobbins 1.21 during the initial boot autodetection process, you'll need to load the appropriate
194 zhen 1.6 modules from /lib/modules, again using <c>modprobe</c>:

225     <section>
226     <body>
227     <p>If you have a PCMCIA network card, you will need to do some additional
228 zhen 1.6 trickery.
229     </p>
230 zhen 1.16 <warn>To avoid problems with <c>cardmgr</c>, you <e>must</e> run it <e>before</e> you enter the chroot

238 drobbins 1.21 <p>As <c>cardmgr</c> detects which hardware is present, your speaker should emit a

240 drobbins 1.21 of course insert the PCMCIA card after loading <c>cardmgr</c> too, if that's
241 zhen 1.6 preferable. (Technically, you need not run
242 drobbins 1.21 <c>cardmgr</c> if you know exactly which module your PCMCIA card requires.
243 zhen 1.6 But if you don't, loading all PCMCIA modules and see which sticks won't work,
244     as all PCMCIA modules load obligingly and hang around for a PCMCIA card to
245 drobbins 1.21 drop by. <c>cardmgr</c> will also unload the module(s) for any card when you

270     <title> Automatic Network Configuration </title>
271     <body>
272     <p>The Gentoo Linux install lets you configure a working network, allowing you to use
273 drobbins 1.21 <c>ssh</c>, <c>scp</c>, <c>lynx</c>, <c>irssi</c> or <c>wget</c> as needed before even beginning the installation process.
274 zhen 1.6 Even if you don't need to do these things now, you should go ahead and set up networking now.
275     Once networking is up, Portage will be able to use your configured network once you are inside
276     the chroot environment (required for installing Gentoo Linux).
277     The simplest way to set up networking is to run our new <c>net-setup</c>
278     script. </p>

294 zhen 1.6 add a <c>-h myhostname</c> flag to the dhcpcd command line above.
295     </note>
296 zhen 1.16 <p>If you receive <i>dhcpConfig</i> warnings, don't panic; the errors

301     <title>Manual Static Configuration</title>
302     <body>
303     <p>We need to setup just enough networking so that we can download
304 zhen 1.6 sources for the system build, as well as the required localhost interface.
305     Type in the following commands, replacing
306     $IFACE with your network interface (typically <c>eth0</c>), $IPNUM
307     with your IP address, $BCAST with your broadcast address, and $NMASK
308     with your network mask. For the <c>route</c> command, replace

374     <title>Partition Configuration</title>
375     <section>
376     <body>
377     <p>Now that the kernel can see the network card and disk controllers, it's time
378 zhen 1.6 to set up disk partitions for Gentoo Linux.
379     </p>
380 zhen 1.16 <p>Here's a quick overview of the standard Gentoo Linux partition layout.
381 zhen 1.6 We're going to create at least three partitions: a swap partition, a root
382     partition (to hold the bulk of Gentoo Linux), and a special boot partition.
383     The boot partition is designed to hold the GRUB or LILO boot loader information as well as
384     your Linux kernel(s). The boot partition gives us a safe place to store
385     everything related to booting Linux. During normal day-to-day Gentoo Linux use,
386     your boot partition should remain <e>unmounted</e>. This prevents your kernel
387     from being made unavailable to GRUB (due to filesystem corruption) in the event
388     of a system crash, preventing the chicken-and-egg problem where GRUB can't read
389     your kernel (since your filesystem isn't consistent) but you can't bring your
390     filesystem back to a consistent state (since you can't boot!)
391     </p>
392 zhen 1.16 <p>Now, on to filesystem types. Right now, you have four filesystem options:
393 zhen 1.6 XFS, ext2, ext3 (journaling) and ReiserFS. ext2 is the tried and true Linux
394     filesystem but doesn't have metadata journaling. ext3 is the new version of
395     ext2 with both metadata journaling and ordered data writes, effectively
396     providing data journaling as well. ReiserFS is a B*-tree based filesystem
397     that has very good small file performance, and greatly outperforms both ext2 and
398     ext3 when dealing with small files (files less than 4k), often by a factor of
399     10x-15x. ReiserFS also scales extremely well and has metadata journaling.
400     As of kernel 2.4.18+, ReiserFS is finally rock-solid and highly recommended.
401     XFS is a filesystem with metadata journaling that
402 drobbins 1.21 is fully supported under Gentoo Linux's <path>xfs-sources</path> kernel, but
403     is generally not recommended due to its tendency to lose recently-modified
404     data if your system locks up or unexpectedly reboots (due to a power failure, for instance.)
405 zhen 1.6 </p>
406 zhen 1.16 <p>If you're looking for the most standard filesystem, use ext2. If you're looking
407 zhen 1.6 for the most rugged journalled filesystem, use ext3. If you're looking for a
408     high-performance filesystem with journaling support, use ReiserFS; both ext3 and ReiserFS are
409 drobbins 1.21 mature and refined.
410 zhen 1.6 Here are our basic recommended filesystem
411     sizes and types:
412     </p>
413 zhen 1.16 <table>

421     <ti>boot partition, containing kernel(s) and boot information</ti>
422     <ti>100 Megabytes</ti>
423     <ti>ext2/3 highly recommended (easiest); if ReiserFS then mount with <c>-o notail</c></ti>
424     <ti>/dev/hda1</ti>

427     <ti>swap partition (no longer a 128 Megabyte limit)</ti>
428     <ti>&gt;=2*Amount of RAM in this system is recommended but no longer (as of kernel 2.4.10) required</ti>
429     <ti>Linux swap</ti>

431     </tr>
432     <tr>
433     <ti>root partition, containing main filesystem (/usr, /home, etc)</ti>
434     <ti>&gt;=1.5 Gigabytes</ti>
435     <ti>ReiserFS, ext3 recommended; ext2 ok</ti>
436     <ti>/dev/hda3</ti>
437     </tr>
438     </table>
439 drobbins 1.21 <p>Before creating filesystems, you may want to initialize the
440     beginning of your HD using <c>dd</c>. Doing this will ensure that your new filesystem
441     will not be mis-indentified by Linux's mounting code.
442     This can be done as follows:
443 zhen 1.6 </p>
444 zhen 1.16 <pre caption="Initializing first 1024 Sectors of HD">
445 drobbins 1.21 # <c>dd if=/dev/zero of=/dev/hdxy bs=1024 count=1024 </c>
446 zhen 1.26 <comment>Replace /dev/hdxy with the device you wish to &quot;clean.&quot;</comment>
447 zhen 1.6 </pre>
448 drobbins 1.21 <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
449     should be of type 82 if swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
450     <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
451     <c>fdisk</c>. Just type <c>cfdisk</c> to run it; by default, cfdisk will work with <b>/dev/hda</b>. If /dev/hda is not the hard disk you want to partition, give the right value to cfdisk as a parameter. For example: <c>cfdisk /dev/hde</c></note>
452 zhen 1.26 <note>If <c>fdisk</c> or <c>cfdisk</c> instruct you to do so, please reboot to allow your system to detect the
453 drobbins 1.21 new partition configuration.</note>
454 zhen 1.26 <note>If you are using RAID your partitions will be a little different. You
455 drobbins 1.21 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X is
456     the arrays you have made, so if you only have made 1 array, then it will be
457     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
458 zhen 1.26 <p>Once you've created your partitions, it's time to initialize
459 zhen 1.6 the filesystems that will be used to house our data. Initialize swap as follows:</p>
460 zhen 1.16 <pre caption="Initializing Swap">
461 drobbins 1.1 # <c>mkswap /dev/hda2</c>
462 zhen 1.6 </pre>
463 zhen 1.16 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems.</p>
464     <pre caption="Creating an ext2 Filesystem">
465 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
466 zhen 1.6 </pre>
467 zhen 1.16 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command.</p>
468     <pre caption="Creating a XFS Filesystem">
469 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
470 zhen 1.6 </pre>
471 zhen 1.16 <note>
472 zhen 1.6 You may want to add a couple of additional flags to the <c>mkfs.xfs</c> command: <c>-d agcount=3 -l size=32m</c>.
473     The <c>-d agcount=3</c> command will lower
474     the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition,
475     so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5.
476     The <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing performance.
477     </note>
478 zhen 1.16 <warn>
479 zhen 1.6 If you are installing an XFS partition over a previous ReiserFS partition,
480     later attempts to mount may fail without an explicit <c>mount -t xfs</c>.
481     The solution is to zero out the partition before creating the XFS filesystem:
482     <c>dd if=/dev/zero of=/dev/hd<comment>x</comment> bs=1k</c>.
483     </warn>
484 zhen 1.16 <p>If you'd like to use ext3, you can create ext3 filesystems using <c>mke2fs -j</c>.</p>
485     <pre caption="Creating an ext3 Filesystem">
486 drobbins 1.1 # <c>mke2fs -j /dev/hda3</c>
487 zhen 1.6 </pre>

509 zhen 1.6 and we'll mount our filesystems to these mountpoints. </p>

520     </p>
521 zhen 1.26 <p>If you decide to use the GRP (Gentoo Reference Platform), now is the time to set it up.
522     </p>
523     <p>First, you will need to <c>cd</c> to the location of the packages directory, for the
524     liveCD you will find it at <path>/mnt/cdrom/gentoo/packages</path>. In that directory you
525     will find the <c>grp-install.sh</c> script, an <i>All</i> directory that contains all of the binary
526     packages, and a list of available GRP packages. To install any/all of these
527     package sets you should do the following: </p>
528     <pre caption="Using GRP">
529     # <c>sh grp-install.sh &lt;list of package lists&gt;</c>
530     <comment>where &lt;list of package lists&gt; may be any of the *-list.txt files found in the same directory.</comment>
531 drobbins 1.21 </pre>
532 zhen 1.26 <p><c>grp-install.sh</c> can be run multiple times without replacing existing installations. You can
533     do a <c>sh grp-install.sh</c> for a basic usage description if you are still a bit foggy.
534     </p>
535     <impo>If your <e>boot</e> partition (the one holding the kernel) is ReiserFS, be sure to mount it
536 zhen 1.6 with the <c>-o notail</c> option so GRUB gets properly installed. Make sure
537     that <c>notail</c> ends up in your new <path>/etc/fstab</path> boot partition entry, too.
538     We'll get to that in a bit.
539     </impo>
540 zhen 1.16 <impo>If you are having problems mounting your boot partition with ext2, try using
541 zhen 1.6 <c>mount /dev/hXX /mnt/gentoo/boot -t ext2 </c> </impo>

616     <p>Now that you have a working copy of the Portage tree, people using stage1 to
617 zhen 1.6 install will need to bootstrap their Gentoo Linux system as follows. First
618     edit the file <path>/etc/make.conf</path>. In this file, you should set your
619     <c>USE</c> flags, which specify optional functionality that you would
620     like to be built into packages; generally, the defaults (an <e>empty</e>
621     or unset <c>USE</c> variable) are fine.

754     <p>At this point, you should have system that's ready for final configuration.
755     We'll start the configuration process by setting the timezone. By setting the timezone before building

834 zhen 1.16 <warn>For your kernel to function properly, there are several options that you will
835 zhen 1.6 need to ensure are in the kernel proper -- that is, they should <i>be enabled and not
836 zhen 1.16 compiled as modules</i>. You will need to enable the <i>&quot;Code maturity
837     level options --&gt; Prompt for development and/or incomplete code/drivers&quot;</i>
838 zhen 1.6 option to see several of these selections.
839 zhen 1.16 Under the &quot;File systems&quot; section, be sure to enable the <i>&quot;Device File System&quot;</i> (note that
840     you <e>don't</e> need to enable the &quot;/dev/pts file system support&quot; option). You'll also
841     need to enable the <i>&quot;Virtual Memory Filesystem&quot;</i>. Be sure to enable &quot;ReiserFS&quot; if you have
842     any ReiserFS partitions; the same goes for &quot;Ext3&quot;. If you're using XFS, enable the
843     &quot;SGI XFS filesystem support&quot;
844 zhen 1.6 option. It's always a good idea to leave ext2
845     enabled whether you are using it or not. Also, most people using IDE hard drives will
846 zhen 1.16 want to enable the &quot;USE DMA by default&quot; option; otherwise, your IDE drives may perform
847     very poorly. Of course, remember to enable &quot;IDE disk&quot; support as well -- otherwise your
848 zhen 1.6 kernel won't be able to see your IDE disks.
849     </warn>
850 zhen 1.16 <p>If you are using hardware RAID you will need to enable a couple more options in the kernel:
851 zhen 1.6 For Highpoint RAID controllers select hpt366 chipset support, support for IDE RAID controllers and Highpoint
852     370 software RAID.For Promise RAID controllers select PROMISE PDC202{46|62|65|67|68|69|70} support,
853     support for IDE RAID
854     controllers and Support Promise software RAID (Fasttrak(tm))
855     </p>
856 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
857 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
858 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
859     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but
860     are not definitely needed, neither does the &quot;PPP over Ethernet&quot; option,
861 zhen 1.6 that might only be used by <i>rp-pppoe</i> when configured to do kernel mode PPPoE.
862     </p>
863 zhen 1.16 <p>If you have an IDE cd burner, then you need to enable SCSI emulation in the
864     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA and ATAPI Block
865     devices&quot; ---&gt; &quot;SCSI emulation support&quot; (I usually make it a module), then
866     under &quot;SCSI support&quot; enable &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and
867     &quot;SCSI generic support&quot; (again, I usually compile them as modules). If you
868     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
869     &gt;&gt; /etc/modules.autoload</c> to have them automatically added at boot time.
870 zhen 1.6 </p>
871 zhen 1.16 <note>
872 zhen 1.6 For those who prefer it,
873     it is now possible to install Gentoo Linux with a 2.2 kernel.
874 drobbins 1.21 However, doing this comes at a price:
875 zhen 1.6 you will lose many of the nifty features that
876     are new to the 2.4 series kernels (such as XFS and tmpfs
877     filesystems, iptables, and more), although the 2.2 kernel sources can be
878 drobbins 1.21 patched with ReiserFS and devfs support.
879     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
880 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
881     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
882     line in <path>/boot/grub/grub.conf</path> for the 2.2 kernel so that a ramdisk is mounted
883     for the bootscripts instead of tmpfs. If you choose not to use devfs, then
884     <e>gentoo=notmpfs,nodevfs</e> should be used instead.
885     </note>
886 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
887 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
888     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
889     to gravitate away from sysklogd (not very good performance) and towards the
890     newer alternatives.
891     If in doubt, you may want to try metalog, since it seems to be quite popular.
892     To merge your logger of choice, type <e>one</e> of the next four lines:

913 zhen 1.16 <impo>
914 zhen 1.6 Metalog flushes output to the disk in blocks, so messages aren't immediately recorded into
915     the system logs. If you are trying to debug a daemon, this performance-enhancing behavior
916     is less than helpful. When your Gentoo Linux system is up and running, you can send
917     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
918     <i>tail -f <path>/var/log/everything/current</path></i> will now work
919     in real time, as expected),

1122     <title>Final steps: Configure GRUB</title>
1123     <section>
1124     <body>
1125     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1126 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1127     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1128 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1129 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1130     cdrom players, burners, and that the same construct can be used with scsi drives.
1131     (Normally they get higher numbers than ide drives except when the bios is configured
1132     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1133     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1134     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1136     It might sound tricky, and tricky it is indeed, but as we will see, grub
1137     offers a tab completion mechanism that comes handy for those of you having
1138     a lot of harddrives and partitions and who are a little lost in the
1139     grub numbering scheme. Having gotten the feel for that,
1140     it's time to install GRUB.
1141     </p>
1142 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1143     <pre caption="Installing GRUB">
1144 drobbins 1.1 # <c>grub</c>
1145 zhen 1.6 </pre>
1146 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1147 zhen 1.6 this time.
1148     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1149     grub setup for RAID controllers
1150     </impo>
1151 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1152 zhen 1.6 command-line prompt. Now, you need to type in the
1153     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1154     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1155     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1156     I want to type are:
1157     </p>
1158 zhen 1.16 <pre caption="GRUB Commands">
1159 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1160     grub&gt; <c>setup (hd0)</c>
1161     grub&gt; <c>quit</c>
1162 zhen 1.6 </pre>
1163 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1164 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1165     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1166     </c> command tells GRUB where to install the
1167     boot record - it will be configured to look for its special files at the <c>root
1168     ( )</c> location that you specified. In my case, I want the boot record on the
1169     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1170     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1171     could install GRUB to the boot record of a particular partition. In that case,
1172     I'd specify a particular partition rather than the entire disk. Once the GRUB
1173     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1175     <note> The tab completion mechanism of grub can be used from within grub,
1176     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1177     be prompted with a list of the available devices (not only harddrives),
1178     hitting the TAB key having written <c> root (hd</c>, grub would print the
1179     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1180     would make grub print the list of partitions on the first harddrive.
1182     Checking the syntax of the grub location with completion should really help
1183     to make the right choice.
1184     </note>
1186     Gentoo Linux is now
1187     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1188     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1189     </p>
1190 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1191 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1192     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1193 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:
1194 zhen 1.6 </p>
1195 zhen 1.16 <pre caption="Grub.conf for GRUB">

1215 zhen 1.6 (hd0,0) should be written without any spaces inside the parentheses.
1216     </note>
1217 zhen 1.16 <impo>
1218 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1219 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1220     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1221 zhen 1.6 </impo>
1222 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1223 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1224     and shows you how to use GRUB to boot a bootable Windows partition.
1225     </p>
1226 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1227 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1228     your root filesystem. <path>(hd0,5)</path> contains the NT boot
1229     loader.
1230 zhware 1.9 </note>
1231 zhen 1.16 <note>
1232 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>.
1233 zhen 1.6 </note>
1234 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1235 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1236     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1237     turn off devfs by default (not recommended unless you know what you're doing) by
1238     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1239     </p>
1240 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1241 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1242     devfs is enabled by default.

1248     <title>Final steps: Configure LILO</title>
1249     <section>
1250     <body>
1251 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1252     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1253     LILO if you would like to use it instead of GRUB:
1254 zhen 1.16 </p>
1255     <p>The first step is to emerge LILO:
1256     </p>
1257     <pre caption="Emerging LILO">
1258     # <c>emerge lilo</c>
1259     </pre>
1260     <p>Now it is time to configure LILO. I will give you a small <i>lilo.conf</i> to use, and I will explain
1261     the different parts of the file.
1262     </p>
1263     <pre caption="Example lilo.conf">
1264     boot=/dev/hda
1265     map=/boot/map
1266     install=/boot/boot.b
1267     prompt
1268     timeout=50
1269     message=/boot/message
1270     lba32
1271     default=linux
1273     image=/boot/vmlinuz-2.4.20
1274     label=linux
1275     initrd=/boot/initrd-2.4.20.img
1276     read-only
1277     root=/dev/hda5
1279     #For dual booting windows/other OS
1280     other=/dev/hda1
1281     label=dos
1283     </pre>
1284     <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
1285     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1286     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1287     In normal use, this should not be altered. If the install line is missing, LILO will
1288     assume a default of /boot/boot.b as the file to be used. </li>
1289     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1290     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1291     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1292     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1293     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1294     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1295     operating system or kernel to boot. </li>
1296     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1297     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1298     your system in an unbootable state. </li>
1299     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1300     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1301     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1302     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1303     it is also the name referred to by the default line. </li>
1304     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1305     to actually initialize and start the devices that makes booting the kernel possible. The initial
1306     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1307     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1308     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1309     altered during the boot process. </li>
1310     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1311     <note>Thanks to <uri link="http://www.redhat.com">Redhat.com</uri> for this information.
1312     </note>
1313     <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information
1314     into the MBR:
1315     </p>
1316     <pre caption="Running LILO">

1327     <title>GRUB Bootdisks</title>
1328     <body>
1329 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1330 zhen 1.16 time you install any Linux distribution. This is a security
1331 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
1332     disk. With these types of hardware RAID,
1333     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1334     make a GRUB
1335     boot disk, and when you reboot the first time you can install GRUB
1336 zhen 1.6 to the MBR. Make your
1337     bootdisk like this:

1372     <p>Now, Gentoo Linux is installed. The only remaining step is to exit the chrooted shell,
1373 zhen 1.6 udpate necessary configuration files,
1374     safely unmount your partitions
1375     and reboot the system:

1386 zhen 1.6 </pre>
1387 zhen 1.16 <note>
1388 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1389     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1390     generally make changes to the files in <path>/etc/modules.d</path>.
1391     </note>
1392 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1393 zhen 1.6 use the bootdisk for the first reboot.

1415     <body>
1416     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1417 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1418     us in set priorities our development. Installing it is completely optional, and it would be greatly
1419     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1420     </p>
1421 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1422 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1423     to individually identify your system, nor will it be mached against an IP address or
1424     other personal information. Every precaution has been taken to assure your privacy in the
1425     development of this system. The following are the things that we are monitoring
1426 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1427 zhen 1.6 </p>
1428 zhen 1.16 <ul>
1429     <li>installed packages and their version numbers</li>
1430     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1431     <li>memory information (total available physical RAM, total available swap space)</li>
1432     <li>PCI cards and network controller chips</li>
1433     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1434     </ul>
1435     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1436 zhen 1.6 (just as it is to the developers).
1437     </p>
1438 zhen 1.16 <ul>
1439     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1440 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1441 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1442     <li>The IP address your data transmission originates from will never be logged
1443     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
