33 zhen 1.16 <abstract>These instructions step you through the process of installing Gentoo
34 drobbins 1.21 Linux 1.4_rc2. The Gentoo Linux installation process supports various installation
35 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
36     scratch.

41     <title>About the Install</title>
42     <section>
43     <body>
44 zhen 1.26 <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
45 drobbins 1.21 as many SCSI CD-ROM, assuming that your CD-ROM and BIOS both support booting.
46     Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
47     kernel) as well as support for all SCSI devices (available as modules.) In
48     addition, we provide modules for literally every kind of network card that
49     Linux supports, as well as tools to allow you to configure your network and
50     establish outbound (as well as inbound) <c>ssh</c> connections and download
51     files. </p>
52 zhen 1.26 <p>To install from the build CD, you will need to have a 486+ processor and
53 drobbins 1.21 ideally at least 64 Megabytes of RAM. (Gentoo linux has been successfully
54     built with 64MB of RAM + 64MB of swap space, but the build process is awfully
55     slow under those conditions.)</p>
56 zhen 1.26 <p>Gentoo Linux can be installed using one of three &quot;stage&quot; tarball files. The
57 drobbins 1.21 one you choose depends on how much of the system you want to compile yourself.
58     The stage1 tarball is used when one wants to bootstrap and build the entire
59     system from scratch. The stage2 tarball is used for building the entire system
60     from scratch, except for the bootstrap part which is already performed for you.
61     And the stage3 tarball already contains a basic Gentoo Linux system that has
62     been optimized for your system.</p>
63 zhen 1.33 <p> So, how does one begin the install process? First, you'll want to decide
64 drobbins 1.21 which one of our LiveCD ISO images to grab from
65 drobbins 1.23 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc2/x86/</uri>.
66 drobbins 1.22 In this directory, you'll see several subdirectories such as <c>athlon</c>
67 drobbins 1.24 for each of our various architecture-specific builds. Here's a low-down on
68     each arch directory and what it contains:</p>

100     <ti>Stage 2 and 3 tarballs, GRP packages and liveCD for Intel Pentium III and Pentium 4 CPUs</ti>
101     </tr>
102     </table>
103     <p>Inside each of these directories,
104 drobbins 1.22 you'll find a <path>livecd/</path> directory that contains LiveCDs. While these LiveCDs
105     will boot on any architecture, the install-related tarballs are optimized for a particular
106 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>
107 drobbins 1.24 directory which can be used to install on anything.
108 drobbins 1.22 </p>
109 zhen 1.26 <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
110 drobbins 1.24 using CD burning software. Currently, we have two types of LiveCDs. The first
111 zhen 1.26 carries the &quot;gentoo-basic&quot; label, and is approximately 40MB in size and lives
112 drobbins 1.24 in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
113     allow for a initial quick download and contains a stage1 tarball that can be
114     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
115 zhen 1.26 <p>The second flavor of LiveCD we currently offer is labelled &quot;livecd-grp.&quot;
116 drobbins 1.24 These CDs (found in their respective <path>arch/livecd</path> directories)
117     contain stage1, 2 and 3 tarballs, and also contain a set of GRP packages
118 zhen 1.50 optimized for a specific architecture. GRP is simply precompiled packages for
119     very large applications, such as XFree86. KDE, GNOME, OpenOffice, etc.
120     Using these LiveCDs, it will be possible
121 drobbins 1.24 for you to install a fully-functional Gentoo Linux system very quickly. The
122     downside is that these ISO images are large -- around 600MB -- so they can take
123     a while to download.</p>
124 zhen 1.26 <info>If for some reason your install gets interrupted at some point, you can
125 drobbins 1.24 reboot and restart. For example, if you have partitioned, installed the stageX
126     tarball, and are ready to chroot, you can restart the install if necessary.
127     Just re-boot with the LiveCD, then mount your drives/partitions to
128     <path>/mnt</path> as normal. Basically, you can do this at about any point
129     during the install, just not before partitioning for obvious reasons. </info>
130 zhen 1.26 <warn>If you encounter a problem with any part of the install and wish to
131 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
132     needs to be moved upstream to the package maintainers (ie KDE) the
133     <e>developers</e> will take care of that. </warn>
134 zhen 1.26 <p>Now, let's quickly review the install process. First, we'll download, burn
135 drobbins 1.21 and boot a LiveCD. After getting a root prompt, we'll create partitions, create
136     our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
137     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
138     our systems to stage3. Once our systems are at stage3, we can configure them
139     (tweaking config files, installing a bootloader, etc) and boot them and have a
140     fully-functional Gentoo Linux system. Depending on what stage of the build
141     process you're starting from, here's what's required for installation: </p>

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

190     <p>If the PCI autodetection missed some of your hardware, you
191 zhen 1.6 will have to load the appropriate modules manually.
192     To view a list of all available network card modules, type <c>ls

200 zhen 1.16 <p>Now, if you want to be able to access any SCSI hardware that wasn't detected

278     <title> Automatic Network Configuration </title>
279     <body>
280     <p>The Gentoo Linux install lets you configure a working network, allowing you to use
281 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.
282 zhen 1.6 Even if you don't need to do these things now, you should go ahead and set up networking now.
283     Once networking is up, Portage will be able to use your configured network once you are inside
284     the chroot environment (required for installing Gentoo Linux).
285     The simplest way to set up networking is to run our new <c>net-setup</c>
286     script. </p>

313     Type in the following commands, replacing
314     $IFACE with your network interface (typically <c>eth0</c>), $IPNUM
315     with your IP address, $BCAST with your broadcast address, and $NMASK
316     with your network mask. For the <c>route</c> command, replace

382     <title>Partition Configuration</title>
383     <section>
384     <body>
385     <p>Now that the kernel can see the network card and disk controllers, it's time
386 zhen 1.6 to set up disk partitions for Gentoo Linux.
387     </p>
388 zhen 1.16 <p>Here's a quick overview of the standard Gentoo Linux partition layout.
389 zhen 1.6 We're going to create at least three partitions: a swap partition, a root
390     partition (to hold the bulk of Gentoo Linux), and a special boot partition.
391     The boot partition is designed to hold the GRUB or LILO boot loader information as well as
392     your Linux kernel(s). The boot partition gives us a safe place to store
393     everything related to booting Linux. During normal day-to-day Gentoo Linux use,
394     your boot partition should remain <e>unmounted</e>. This prevents your kernel
395     from being made unavailable to GRUB (due to filesystem corruption) in the event
396     of a system crash, preventing the chicken-and-egg problem where GRUB can't read
397     your kernel (since your filesystem isn't consistent) but you can't bring your
398     filesystem back to a consistent state (since you can't boot!)
399     </p>
400 zhen 1.50 <p>Now, on to filesystem types. Right now, you have five filesystem options:
401     XFS, ext2, ext3 (journaling), jfs, and ReiserFS. ext2 is the tried and true Linux
402 zhen 1.6 filesystem but doesn't have metadata journaling. ext3 is the new version of
403     ext2 with both metadata journaling and ordered data writes, effectively
404     providing data journaling as well. ReiserFS is a B*-tree based filesystem
405     that has very good small file performance, and greatly outperforms both ext2 and
406     ext3 when dealing with small files (files less than 4k), often by a factor of
407     10x-15x. ReiserFS also scales extremely well and has metadata journaling.
408     As of kernel 2.4.18+, ReiserFS is finally rock-solid and highly recommended.
409     XFS is a filesystem with metadata journaling that
410 drobbins 1.21 is fully supported under Gentoo Linux's <path>xfs-sources</path> kernel, but
411     is generally not recommended due to its tendency to lose recently-modified
412     data if your system locks up or unexpectedly reboots (due to a power failure, for instance.)
413 zhen 1.50 Finially, jfs is IBM's own high performance journaling filesystem. Since it is obscure, we cannot comment either positvely nor negatively on its stability.</p>
414 zhen 1.16 <p>If you're looking for the most standard filesystem, use ext2. If you're looking
415 zhen 1.6 for the most rugged journalled filesystem, use ext3. If you're looking for a
416     high-performance filesystem with journaling support, use ReiserFS; both ext3 and ReiserFS are
417 drobbins 1.21 mature and refined.
418 zhen 1.6 Here are our basic recommended filesystem
419     sizes and types:

469 drobbins 1.21 <p>Before creating filesystems, you may want to initialize the
470     beginning of your HD using <c>dd</c>. Doing this will ensure that your new filesystem
471     will not be mis-indentified by Linux's mounting code.
472     This can be done as follows:
473 zhen 1.6 </p>
474 zhen 1.16 <pre caption="Initializing first 1024 Sectors of HD">

477 zhen 1.6 </pre>
478 zhware 1.43 <warn>The command above will destroy all data from <path>/dev/hdxy</path>.
479     Be careful and check twice which partition you specify for zeroing.
480     If you make a mistake it might result in a loss of data.
481     </warn>
482 drobbins 1.21 <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
483     should be of type 82 if swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
484     <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
485     <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>
486 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
487 drobbins 1.21 new partition configuration.</note>
488 zhen 1.26 <note>If you are using RAID your partitions will be a little different. You
489 drobbins 1.21 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X is
490     the arrays you have made, so if you only have made 1 array, then it will be
491     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
492 zhen 1.26 <p>Once you've created your partitions, it's time to initialize
493 zhen 1.6 the filesystems that will be used to house our data. Initialize swap as follows:</p>

507     The <c>-d agcount=3</c> command will lower
508     the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition,
509     so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5.
510     The <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing performance.
511     </note>
512 zhen 1.16 <warn>
513 zhen 1.6 If you are installing an XFS partition over a previous ReiserFS partition,
514     later attempts to mount may fail without an explicit <c>mount -t xfs</c>.
515     The solution is to zero out the partition before creating the XFS filesystem:
516     <c>dd if=/dev/zero of=/dev/hd<comment>x</comment> bs=1k</c>.
517     </warn>

912 zhen 1.16 <warn>For your kernel to function properly, there are several options that you will
913 zhen 1.6 need to ensure are in the kernel proper -- that is, they should <i>be enabled and not
914 zhen 1.16 compiled as modules</i>. You will need to enable the <i>&quot;Code maturity
915     level options --&gt; Prompt for development and/or incomplete code/drivers&quot;</i>
916 zhen 1.6 option to see several of these selections.
917 zhen 1.50 Under the &quot;File systems&quot; section, be sure to enable the <i>&quot;/dev&quot; file system support</i> (note that
918 zhen 1.16 you <e>don't</e> need to enable the &quot;/dev/pts file system support&quot; option). You'll also
919     need to enable the <i>&quot;Virtual Memory Filesystem&quot;</i>. Be sure to enable &quot;ReiserFS&quot; if you have
920     any ReiserFS partitions; the same goes for &quot;Ext3&quot;. If you're using XFS, enable the
921     &quot;SGI XFS filesystem support&quot;
922 zhen 1.6 option. It's always a good idea to leave ext2
923     enabled whether you are using it or not. Also, most people using IDE hard drives will
924 zhen 1.16 want to enable the &quot;USE DMA by default&quot; option; otherwise, your IDE drives may perform
925     very poorly. Of course, remember to enable &quot;IDE disk&quot; support as well -- otherwise your
926 zhen 1.6 kernel won't be able to see your IDE disks.
927     </warn>
928 zhen 1.16 <p>If you are using hardware RAID you will need to enable a couple more options in the kernel:
929 zhen 1.6 For Highpoint RAID controllers select hpt366 chipset support, support for IDE RAID controllers and Highpoint
930     370 software RAID.For Promise RAID controllers select PROMISE PDC202{46|62|65|67|68|69|70} support,
931     support for IDE RAID
932     controllers and Support Promise software RAID (Fasttrak(tm))
933     </p>
934 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
935 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
936 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
937     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but
938     are not definitely needed, neither does the &quot;PPP over Ethernet&quot; option,
939 zhen 1.6 that might only be used by <i>rp-pppoe</i> when configured to do kernel mode PPPoE.
940     </p>
941 zhen 1.16 <p>If you have an IDE cd burner, then you need to enable SCSI emulation in the
942     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA and ATAPI Block
943     devices&quot; ---&gt; &quot;SCSI emulation support&quot; (I usually make it a module), then
944     under &quot;SCSI support&quot; enable &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and
945     &quot;SCSI generic support&quot; (again, I usually compile them as modules). If you
946     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
947     &gt;&gt; /etc/modules.autoload</c> to have them automatically added at boot time.
948 zhen 1.6 </p>
949 zhen 1.16 <note>
950 zhen 1.6 For those who prefer it,
951     it is now possible to install Gentoo Linux with a 2.2 kernel.
952 drobbins 1.21 However, doing this comes at a price:
953 zhen 1.6 you will lose many of the nifty features that
954     are new to the 2.4 series kernels (such as XFS and tmpfs
955     filesystems, iptables, and more), although the 2.2 kernel sources can be
956 drobbins 1.21 patched with ReiserFS and devfs support.
957     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
958 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
959     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
960     line in <path>/boot/grub/grub.conf</path> for the 2.2 kernel so that a ramdisk is mounted
961     for the bootscripts instead of tmpfs. If you choose not to use devfs, then
962     <e>gentoo=notmpfs,nodevfs</e> should be used instead.
963     </note>
964 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
965 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
966     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
967     to gravitate away from sysklogd (not very good performance) and towards the
968     newer alternatives.
969     If in doubt, you may want to try metalog, since it seems to be quite popular.
970     To merge your logger of choice, type <e>one</e> of the next four lines:

994     is less than helpful. When your Gentoo Linux system is up and running, you can send
995     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
996     <i>tail -f <path>/var/log/everything/current</path></i> will now work
997     in real time, as expected),
998     and a USR2 signal to turn buffering back on

1226 zhen 1.49 <title>Configuring GRUB</title>
1227 zhen 1.16 <body>
1228     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1229 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1230     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1231 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1232 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1233     cdrom players, burners, and that the same construct can be used with scsi drives.
1234     (Normally they get higher numbers than ide drives except when the bios is configured
1235     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1236     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1237     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1239     It might sound tricky, and tricky it is indeed, but as we will see, grub
1240     offers a tab completion mechanism that comes handy for those of you having
1241     a lot of harddrives and partitions and who are a little lost in the
1242     grub numbering scheme. Having gotten the feel for that,
1243     it's time to install GRUB.
1244     </p>
1245 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1246     <pre caption="Installing GRUB">
1247 zhen 1.51 # <c>emerge grub</c>
1248 drobbins 1.1 # <c>grub</c>
1249 zhen 1.6 </pre>
1250 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1251 zhen 1.6 this time.
1252     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1253     grub setup for RAID controllers
1254     </impo>
1255 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1256 zhen 1.6 command-line prompt. Now, you need to type in the
1257     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1258     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1259     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1260     I want to type are:
1261     </p>
1262 zhen 1.16 <pre caption="GRUB Commands">
1263 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1264     grub&gt; <c>setup (hd0)</c>
1265 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
1266     grub&gt; <c>setup (hd0) (hd0,4) </c>
1267     <codenote>The second parameter above identifies the boot partition</codenote>
1268 drobbins 1.1 grub&gt; <c>quit</c>
1269 zhen 1.6 </pre>
1270 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1271 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1272     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1273     </c> command tells GRUB where to install the
1274     boot record - it will be configured to look for its special files at the <c>root
1275     ( )</c> location that you specified. In my case, I want the boot record on the
1276     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1277     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1278     could install GRUB to the boot record of a particular partition. In that case,
1279     I'd specify a particular partition rather than the entire disk. Once the GRUB
1280     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1281 zhen 1.52 </p>
1282 zhen 1.6
1283     <note> The tab completion mechanism of grub can be used from within grub,
1284     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1285     be prompted with a list of the available devices (not only harddrives),
1286     hitting the TAB key having written <c> root (hd</c>, grub would print the
1287     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1288     would make grub print the list of partitions on the first harddrive.
1290     Checking the syntax of the grub location with completion should really help
1291     to make the right choice.
1292     </note>
1294 zhen 1.52 <p>
1295 zhen 1.6 Gentoo Linux is now
1296     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1297     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1298     </p>
1299 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1300 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1301     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1302 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:
1303 zhen 1.6 </p>

1325     </note>
1326 zhen 1.16 <impo>
1327 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1328 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1329     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1330 zhen 1.6 </impo>
1331 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1332 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1333     and shows you how to use GRUB to boot a bootable Windows partition.
1334     </p>
1335 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1336 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1337     your root filesystem. <path>(hd0,5)</path> contains the NT boot
1338     loader.
1339 zhware 1.9 </note>
1340 zhen 1.16 <note>
1341 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>.
1342 zhen 1.6 </note>
1343 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1344 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1345     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1346     turn off devfs by default (not recommended unless you know what you're doing) by
1347     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1348     </p>
1349 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1350 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1351     devfs is enabled by default.

1356     <title>Configuring LILO</title>
1357 zhen 1.16 <body>
1358 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1359     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1360     LILO if you would like to use it instead of GRUB:
1361 zhen 1.16 </p>
1362     <p>The first step is to emerge LILO:
1363     </p>
1364     <pre caption="Emerging LILO">
1365     # <c>emerge lilo</c>
1366     </pre>
1367     <p>Now it is time to configure LILO. I will give you a small <i>lilo.conf</i> to use, and I will explain
1368     the different parts of the file.
1369     </p>
1370     <pre caption="Example lilo.conf">
1371     boot=/dev/hda
1372     map=/boot/map
1373     install=/boot/boot.b
1374     prompt
1375     timeout=50
1376     message=/boot/message
1377     lba32

1380     image=/boot/vmlinuz-2.4.20

1384     root=/dev/hda5
1386     #For dual booting windows/other OS
1387     other=/dev/hda1
1388     label=dos
1390     </pre>
1391 zhen 1.52 <ul>
1392 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>
1393     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1394     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1395     In normal use, this should not be altered. If the install line is missing, LILO will
1396     assume a default of /boot/boot.b as the file to be used. </li>
1397     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1398     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1399     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1400     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1401     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1402     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1403     operating system or kernel to boot. </li>
1404     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1405     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1406     your system in an unbootable state. </li>
1407     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1408     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1409     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1410     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1411     it is also the name referred to by the default line. </li>
1412     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1413     to actually initialize and start the devices that makes booting the kernel possible. The initial
1414     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1415     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1416     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1417     altered during the boot process. </li>
1418     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>

1440 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
1441     disk. With these types of hardware RAID,
1442     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1443     make a GRUB
1444     boot disk, and when you reboot the first time you can install GRUB
1445 zhen 1.6 to the MBR. Make your
1446     bootdisk like this:
1447     </p>
1448 zhen 1.16 <pre caption="Creating a GRUB Bootdisk">
1449 drobbins 1.1 # <c>mke2fs /dev/fd0</c>
1450     # <c>mount /dev/fd0 /mnt/floppy</c>
1451     # <c>mkdir -p /mnt/floppy/boot/grub</c>
1452     # <c>cp /usr/share/grub/i386-pc/stage1 /mnt/floppy/boot/grub/</c>

1459     grub&gt; <c>quit</c>
1460 zhen 1.6 </pre>
1461 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>
1462 drobbins 1.21 and <c>setup</c> commands.</p>

1481     <p>Now, Gentoo Linux is installed. The only remaining step is to exit the chrooted shell,
1482 zhen 1.6 udpate necessary configuration files,
1483     safely unmount your partitions
1484     and reboot the system:
1485     </p>
1486 zhen 1.16 <pre caption="Rebooting the System">
1487 drobbins 1.1 # <c>etc-update</c>
1488     # <c>exit</c>
1489     <codenote>This exits the chrooted shell; you can also type <c>^D</c></codenote>
1490     # <c>cd / </c>
1491     # <c>umount /mnt/gentoo/boot</c>
1492     # <c>umount /mnt/gentoo/proc</c>
1493 drobbins 1.36 # <c>umount /mnt/gentoo/dev</c>
1494 drobbins 1.1 # <c>umount /mnt/gentoo</c>
1495     # <c>reboot</c>
1496 zhen 1.6 </pre>
1497 zhen 1.16 <note>
1498 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1499     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1500     generally make changes to the files in <path>/etc/modules.d</path>.
1501     </note>
1502 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1503 zhen 1.6 use the bootdisk for the first reboot.
1504     then go back and install grub the way everyone else did the first
1505 drobbins 1.21 time. You are done -- congratulations!</impo>
1506 zhen 1.16 <p>If you have any questions or would like to get involved with Gentoo Linux development,
1507 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1508 zhen 1.16 (there's a &quot;click to subscribe&quot; link on our <uri link="http://www.gentoo.org">main page</uri>).
1509 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>

1523     <title>Gentoo-Stats</title>
1524     <section>
1525     <body>
1526     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1527 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1528     us in set priorities our development. Installing it is completely optional, and it would be greatly
1529     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1530     </p>
1531 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1532 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1533     to individually identify your system, nor will it be mached against an IP address or
1534     other personal information. Every precaution has been taken to assure your privacy in the
1535     development of this system. The following are the things that we are monitoring
1536 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1537 zhen 1.6 </p>
1538 zhen 1.16 <ul>
1539     <li>installed packages and their version numbers</li>
1540     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1541     <li>memory information (total available physical RAM, total available swap space)</li>
1542     <li>PCI cards and network controller chips</li>
1543     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1544     </ul>
1545     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1546 zhen 1.6 (just as it is to the developers).
1547     </p>
1548 zhen 1.16 <ul>
1549     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1550 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1551 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1552     <li>The IP address your data transmission originates from will never be logged
1553     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1554     </ul>
1555     <p>The installation is easy - just run the following commands:
1556 zhen 1.6 </p>
1557 zhen 1.16 <pre caption="Installing gentoo-stats">
1558 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1559     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1560 zhen 1.6 </pre>
1561 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1562 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1563     to see additional configuration options.
1564     </p>
1565 zhen 1.16 <p>After that, the program should be run on a regular schedule
1566 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1567     </p>
1568 zhen 1.16 <pre caption="Updating gentoo-stats with cron">
1569     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1570     </pre>
1571     <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1572 zhen 1.6 viewed with your favortive pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
