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     optimized for a specific architecture. Using these LiveCDs, it will be possible
119     for you to install a fully-functional Gentoo Linux system very quickly. The
120     downside is that these ISO images are large -- around 600MB -- so they can take
121     a while to download.</p>
122 zhen 1.26 <info>If for some reason your install gets interrupted at some point, you can
123 drobbins 1.24 reboot and restart. For example, if you have partitioned, installed the stageX
124     tarball, and are ready to chroot, you can restart the install if necessary.
125     Just re-boot with the LiveCD, then mount your drives/partitions to
126     <path>/mnt</path> as normal. Basically, you can do this at about any point
127     during the install, just not before partitioning for obvious reasons. </info>
128 zhen 1.26 <warn>If you encounter a problem with any part of the install and wish to
129 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
130     needs to be moved upstream to the package maintainers (ie KDE) the
131     <e>developers</e> will take care of that. </warn>
132 zhen 1.26 <p>Now, let's quickly review the install process. First, we'll download, burn
133 drobbins 1.21 and boot a LiveCD. After getting a root prompt, we'll create partitions, create
134     our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
135     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
136     our systems to stage3. Once our systems are at stage3, we can configure them
137     (tweaking config files, installing a bootloader, etc) and boot them and have a
138     fully-functional Gentoo Linux system. Depending on what stage of the build
139     process you're starting from, here's what's required for installation: </p>

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

187     <body>
188     <p>If the PCI autodetection missed some of your hardware, you
189 zhen 1.6 will have to load the appropriate modules manually.
190     To view a list of all available network card modules, type <c>ls
191     /lib/modules/*/kernel/drivers/net/*</c>. To load a particular module,

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

233     <p>If you have a PCMCIA network card, you will need to do some additional
234 zhen 1.6 trickery.
235     </p>
236 zhen 1.16 <warn>To avoid problems with <c>cardmgr</c>, you <e>must</e> run it <e>before</e> you enter the chroot

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

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

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

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

442     <ti>/dev/hda3</ti>
443     </tr>
444     </table>
445 drobbins 1.21 <p>Before creating filesystems, you may want to initialize the
446     beginning of your HD using <c>dd</c>. Doing this will ensure that your new filesystem
447     will not be mis-indentified by Linux's mounting code.
448     This can be done as follows:
449 zhen 1.6 </p>
450 zhen 1.16 <pre caption="Initializing first 1024 Sectors of HD">
451 zhen 1.34 # <c>dd if=/dev/zero of=/dev/hdxy bs=1K count=1</c>
452 zhen 1.26 <comment>Replace /dev/hdxy with the device you wish to &quot;clean.&quot;</comment>
453 zhen 1.6 </pre>
454 zhware 1.43 <warn>The command above will destroy all data from <path>/dev/hdxy</path>.
455     Be careful and check twice which partition you specify for zeroing.
456     If you make a mistake it might result in a loss of data.
457     </warn>
458 drobbins 1.21 <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
459     should be of type 82 if swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
460     <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
461     <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>
462 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
463 drobbins 1.21 new partition configuration.</note>
464 zhen 1.26 <note>If you are using RAID your partitions will be a little different. You
465 drobbins 1.21 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X is
466     the arrays you have made, so if you only have made 1 array, then it will be
467     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
468 zhen 1.26 <p>Once you've created your partitions, it's time to initialize
469 zhen 1.6 the filesystems that will be used to house our data. Initialize swap as follows:</p>
470 zhen 1.16 <pre caption="Initializing Swap">
471 drobbins 1.1 # <c>mkswap /dev/hda2</c>

482 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>.
483     The <c>-d agcount=3</c> command will lower
484     the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition,
485     so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5.
486     The <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing performance.
487     </note>
488 zhen 1.16 <warn>
489 zhen 1.6 If you are installing an XFS partition over a previous ReiserFS partition,
490     later attempts to mount may fail without an explicit <c>mount -t xfs</c>.
491     The solution is to zero out the partition before creating the XFS filesystem:
492     <c>dd if=/dev/zero of=/dev/hd<comment>x</comment> bs=1k</c>.
493     </warn>
494 zhen 1.16 <p>If you'd like to use ext3, you can create ext3 filesystems using <c>mke2fs -j</c>.</p>

877 zhen 1.16 <warn>For your kernel to function properly, there are several options that you will
878 zhen 1.6 need to ensure are in the kernel proper -- that is, they should <i>be enabled and not
879 zhen 1.16 compiled as modules</i>. You will need to enable the <i>&quot;Code maturity
880     level options --&gt; Prompt for development and/or incomplete code/drivers&quot;</i>
881 zhen 1.6 option to see several of these selections.
882 zhen 1.16 Under the &quot;File systems&quot; section, be sure to enable the <i>&quot;Device File System&quot;</i> (note that
883     you <e>don't</e> need to enable the &quot;/dev/pts file system support&quot; option). You'll also
884     need to enable the <i>&quot;Virtual Memory Filesystem&quot;</i>. Be sure to enable &quot;ReiserFS&quot; if you have
885     any ReiserFS partitions; the same goes for &quot;Ext3&quot;. If you're using XFS, enable the
886     &quot;SGI XFS filesystem support&quot;
887 zhen 1.6 option. It's always a good idea to leave ext2
888     enabled whether you are using it or not. Also, most people using IDE hard drives will
889 zhen 1.16 want to enable the &quot;USE DMA by default&quot; option; otherwise, your IDE drives may perform
890     very poorly. Of course, remember to enable &quot;IDE disk&quot; support as well -- otherwise your
891 zhen 1.6 kernel won't be able to see your IDE disks.
892     </warn>
893 zhen 1.16 <p>If you are using hardware RAID you will need to enable a couple more options in the kernel:
894 zhen 1.6 For Highpoint RAID controllers select hpt366 chipset support, support for IDE RAID controllers and Highpoint
895     370 software RAID.For Promise RAID controllers select PROMISE PDC202{46|62|65|67|68|69|70} support,
896     support for IDE RAID
897     controllers and Support Promise software RAID (Fasttrak(tm))
898     </p>
899 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
900 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
901 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
902     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but
903     are not definitely needed, neither does the &quot;PPP over Ethernet&quot; option,
904 zhen 1.6 that might only be used by <i>rp-pppoe</i> when configured to do kernel mode PPPoE.
905     </p>
906 zhen 1.16 <p>If you have an IDE cd burner, then you need to enable SCSI emulation in the
907     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA and ATAPI Block
908     devices&quot; ---&gt; &quot;SCSI emulation support&quot; (I usually make it a module), then
909     under &quot;SCSI support&quot; enable &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and
910     &quot;SCSI generic support&quot; (again, I usually compile them as modules). If you
911     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
912     &gt;&gt; /etc/modules.autoload</c> to have them automatically added at boot time.
913 zhen 1.6 </p>
914 zhen 1.16 <note>
915 zhen 1.6 For those who prefer it,
916     it is now possible to install Gentoo Linux with a 2.2 kernel.
917 drobbins 1.21 However, doing this comes at a price:
918 zhen 1.6 you will lose many of the nifty features that
919     are new to the 2.4 series kernels (such as XFS and tmpfs
920     filesystems, iptables, and more), although the 2.2 kernel sources can be
921 drobbins 1.21 patched with ReiserFS and devfs support.
922     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
923 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
924     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
925     line in <path>/boot/grub/grub.conf</path> for the 2.2 kernel so that a ramdisk is mounted
926     for the bootscripts instead of tmpfs. If you choose not to use devfs, then
927     <e>gentoo=notmpfs,nodevfs</e> should be used instead.
928     </note>
929 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
930 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
931     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
932     to gravitate away from sysklogd (not very good performance) and towards the
933     newer alternatives.
934     If in doubt, you may want to try metalog, since it seems to be quite popular.
935     To merge your logger of choice, type <e>one</e> of the next four lines:

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

1185 zhen 1.49 <title>Configuring GRUB</title>
1186 zhen 1.16 <body>
1187     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1188 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1189     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1190 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1191 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1192     cdrom players, burners, and that the same construct can be used with scsi drives.
1193     (Normally they get higher numbers than ide drives except when the bios is configured
1194     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1195     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1196     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1197    
1198     It might sound tricky, and tricky it is indeed, but as we will see, grub
1199     offers a tab completion mechanism that comes handy for those of you having
1200     a lot of harddrives and partitions and who are a little lost in the
1201     grub numbering scheme. Having gotten the feel for that,
1202     it's time to install GRUB.
1203     </p>
1204 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1205     <pre caption="Installing GRUB">
1206 drobbins 1.1 # <c>grub</c>
1207 zhen 1.6 </pre>
1208 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1209 zhen 1.6 this time.
1210     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1211     grub setup for RAID controllers
1212     </impo>
1213 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1214 zhen 1.6 command-line prompt. Now, you need to type in the
1215     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1216     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1217     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1218     I want to type are:
1219     </p>
1220 zhen 1.16 <pre caption="GRUB Commands">
1221 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1222     grub&gt; <c>setup (hd0)</c>
1223     grub&gt; <c>quit</c>
1224 zhen 1.6 </pre>
1225 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1226 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1227     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1228     </c> command tells GRUB where to install the
1229     boot record - it will be configured to look for its special files at the <c>root
1230     ( )</c> location that you specified. In my case, I want the boot record on the
1231     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1232     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1233     could install GRUB to the boot record of a particular partition. In that case,
1234     I'd specify a particular partition rather than the entire disk. Once the GRUB
1235     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1236    
1237     <note> The tab completion mechanism of grub can be used from within grub,
1238     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1239     be prompted with a list of the available devices (not only harddrives),
1240     hitting the TAB key having written <c> root (hd</c>, grub would print the
1241     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1242     would make grub print the list of partitions on the first harddrive.
1243    
1244     Checking the syntax of the grub location with completion should really help
1245     to make the right choice.
1246     </note>
1247    
1248     Gentoo Linux is now
1249     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1250     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1251     </p>
1252 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1253 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1254     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1255 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:
1256 zhen 1.6 </p>

1279 zhen 1.16 <impo>
1280 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1281 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1282     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).

1284 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1285 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1286     and shows you how to use GRUB to boot a bootable Windows partition.
1287     </p>
1288 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1289 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1290     your root filesystem. <path>(hd0,5)</path> contains the NT boot

1292 zhware 1.9 </note>
1293 zhen 1.16 <note>
1294 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>.
1295 zhen 1.6 </note>
1296 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1297 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1298     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1299     turn off devfs by default (not recommended unless you know what you're doing) by
1300     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1301     </p>
1302 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add

1309     <title>Configuring LILO</title>
1310 zhen 1.16 <body>
1311 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1312     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1313     LILO if you would like to use it instead of GRUB:
1314 zhen 1.16 </p>
1315     <p>The first step is to emerge LILO:

1321     the different parts of the file.
1322     </p>

1340     other=/dev/hda1
1341     label=dos
1342    
1343     </pre>
1344     <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
1345     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1346     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1347     In normal use, this should not be altered. If the install line is missing, LILO will
1348     assume a default of /boot/boot.b as the file to be used. </li>
1349     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1350     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1351     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1352     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1353     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1354     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1355     operating system or kernel to boot. </li>
1356     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1357     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1358     your system in an unbootable state. </li>
1359     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1360     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1361     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1362     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1363     it is also the name referred to by the default line. </li>
1364     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1365     to actually initialize and start the devices that makes booting the kernel possible. The initial
1366     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1367     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1368     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1369     altered during the boot process. </li>
1370     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>

1389 drobbins 1.21 <p>It is always a good idea to make a boot disk the first

1391 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
1392     disk. With these types of hardware RAID,
1393     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1394     make a GRUB
1395     boot disk, and when you reboot the first time you can install GRUB

1432     <p>Now, Gentoo Linux is installed. The only remaining step is to exit the chrooted shell,
1433 zhen 1.6 udpate necessary configuration files,
1434     safely unmount your partitions
1435     and reboot the system:
1436     </p>
1437 zhen 1.16 <pre caption="Rebooting the System">
1438 drobbins 1.1 # <c>etc-update</c>
1439     # <c>exit</c>
1440     <codenote>This exits the chrooted shell; you can also type <c>^D</c></codenote>
1441     # <c>cd / </c>
1442     # <c>umount /mnt/gentoo/boot</c>
1443     # <c>umount /mnt/gentoo/proc</c>
1444 drobbins 1.36 # <c>umount /mnt/gentoo/dev</c>
1445 drobbins 1.1 # <c>umount /mnt/gentoo</c>
1446     # <c>reboot</c>
1447 zhen 1.6 </pre>
1448 zhen 1.16 <note>
1449 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1450     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1451     generally make changes to the files in <path>/etc/modules.d</path>.
1452     </note>
1453 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1454 zhen 1.6 use the bootdisk for the first reboot.
1455     then go back and install grub the way everyone else did the first
1456 drobbins 1.21 time. You are done -- congratulations!</impo>
1457 zhen 1.16 <p>If you have any questions or would like to get involved with Gentoo Linux development,
1458 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1459 zhen 1.16 (there's a &quot;click to subscribe&quot; link on our <uri link="http://www.gentoo.org">main page</uri>).
1460 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>
1461     that will
1462     help you to continue configuring your new Gentoo Linux system, and a useful
1463     <uri link="http://www.gentoo.org/doc/en/portage-user.xml">Portage user guide</uri>
1464     to help familiarize you with Portage basics. You can find the rest of the Gentoo Documentation
1465 zhen 1.16 <uri link="http://www.gentoo.org/main/en/docs.xml">here</uri>. If you have any other questions
1466 zhen 1.10 involving installation or anything for that matter, please check the Gentoo Linux
1467 zhen 1.16 <uri link="http://www.gentoo.org/doc/en/faq.xml">FAQ</uri>.
1468 zhen 1.6 Enjoy and welcome to Gentoo Linux!

1474     <title>Gentoo-Stats</title>
1475     <section>
1476     <body>
1477     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1478 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1479     us in set priorities our development. Installing it is completely optional, and it would be greatly
1480     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1481     </p>
1482 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1483 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1484     to individually identify your system, nor will it be mached against an IP address or
1485     other personal information. Every precaution has been taken to assure your privacy in the
1486     development of this system. The following are the things that we are monitoring
1487 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1488 zhen 1.6 </p>
1489 zhen 1.16 <ul>
1490     <li>installed packages and their version numbers</li>
1491     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1492     <li>memory information (total available physical RAM, total available swap space)</li>
1493     <li>PCI cards and network controller chips</li>
1494     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1495     </ul>
1496     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1497 zhen 1.6 (just as it is to the developers).
1498     </p>
1499 zhen 1.16 <ul>
1500     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1501 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1502 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1503     <li>The IP address your data transmission originates from will never be logged
1504     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1505     </ul>
1506     <p>The installation is easy - just run the following commands:
1507 zhen 1.6 </p>
1508 zhen 1.16 <pre caption="Installing gentoo-stats">
1509 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1510     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1511 zhen 1.6 </pre>
1512 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1513 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1514     to see additional configuration options.
1515     </p>
1516 zhen 1.16 <p>After that, the program should be run on a regular schedule
1517 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1518     </p>
1519 zhen 1.16 <pre caption="Updating gentoo-stats with cron">
1520     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1521     </pre>
1522     <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1523 zhen 1.6 viewed with your favortive pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
