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

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

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

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

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

195 zhen 1.16 <p>Now, if you want to be able to access any SCSI hardware that wasn't detected
196 drobbins 1.21 during the initial boot autodetection process, you'll need to load the appropriate

230     <p>If you have a PCMCIA network card, you will need to do some additional

232     </p>
233 zhen 1.16 <warn>To avoid problems with <c>cardmgr</c>, you <e>must</e> run it <e>before</e> you enter the chroot

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

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

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

439     <ti>/dev/hda3</ti>
440     </tr>
441     </table>
442 drobbins 1.21 <p>Before creating filesystems, you may want to initialize the
443     beginning of your HD using <c>dd</c>. Doing this will ensure that your new filesystem
444     will not be mis-indentified by Linux's mounting code.
445     This can be done as follows:
446 zhen 1.6 </p>
447 zhen 1.16 <pre caption="Initializing first 1024 Sectors of HD">
448 zhen 1.34 # <c>dd if=/dev/zero of=/dev/hdxy bs=1K count=1</c>
449 zhen 1.26 <comment>Replace /dev/hdxy with the device you wish to &quot;clean.&quot;</comment>
450 zhen 1.6 </pre>
451 drobbins 1.21 <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
452     should be of type 82 if swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
453     <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
454     <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>
455 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
456 drobbins 1.21 new partition configuration.</note>
457 zhen 1.26 <note>If you are using RAID your partitions will be a little different. You
458 drobbins 1.21 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X is
459     the arrays you have made, so if you only have made 1 array, then it will be
460     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
461 zhen 1.26 <p>Once you've created your partitions, it's time to initialize
462 zhen 1.6 the filesystems that will be used to house our data. Initialize swap as follows:</p>
463 zhen 1.16 <pre caption="Initializing Swap">
464 drobbins 1.1 # <c>mkswap /dev/hda2</c>
465 zhen 1.6 </pre>
466 zhen 1.16 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems.</p>
467     <pre caption="Creating an ext2 Filesystem">
468 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
469 zhen 1.6 </pre>
470 zhen 1.16 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command.</p>
471     <pre caption="Creating a XFS Filesystem">
472 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
473 zhen 1.6 </pre>
474 zhen 1.16 <note>
475 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>.
476     The <c>-d agcount=3</c> command will lower
477     the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition,
478     so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5.
479     The <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing performance.
480     </note>
481 zhen 1.16 <warn>
482 zhen 1.6 If you are installing an XFS partition over a previous ReiserFS partition,
483     later attempts to mount may fail without an explicit <c>mount -t xfs</c>.
484     The solution is to zero out the partition before creating the XFS filesystem:
485     <c>dd if=/dev/zero of=/dev/hd<comment>x</comment> bs=1k</c>.
486     </warn>
487 zhen 1.16 <p>If you'd like to use ext3, you can create ext3 filesystems using <c>mke2fs -j</c>.</p>

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

935     for a sample configuration file.
936     </warn>
937 zhen 1.16 <impo>
938 zhen 1.6 Metalog flushes output to the disk in blocks, so messages aren't immediately recorded into
939     the system logs. If you are trying to debug a daemon, this performance-enhancing behavior
940     is less than helpful. When your Gentoo Linux system is up and running, you can send
941     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
942     <i>tail -f <path>/var/log/everything/current</path></i> will now work
943     in real time, as expected),
944     and a USR2 signal to turn buffering back on
945 zhen 1.39 again. If you want to disable buffering permanently, you can change METALOG_OPTS="-B" to METALOG_OPTS="-B -s"
946     in <path>/etc/conf.d/metalog</path>.

1152     <title>Final steps: Configure GRUB</title>
1153     <section>
1154     <body>
1155     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1156 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1157     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1158 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1159 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1160     cdrom players, burners, and that the same construct can be used with scsi drives.
1161     (Normally they get higher numbers than ide drives except when the bios is configured
1162     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1163     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1164     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1165    
1166     It might sound tricky, and tricky it is indeed, but as we will see, grub
1167     offers a tab completion mechanism that comes handy for those of you having
1168     a lot of harddrives and partitions and who are a little lost in the
1169     grub numbering scheme. Having gotten the feel for that,
1170     it's time to install GRUB.
1171     </p>
1172 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1173     <pre caption="Installing GRUB">
1174 drobbins 1.1 # <c>grub</c>
1175 zhen 1.6 </pre>
1176 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1177 zhen 1.6 this time.
1178     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1179     grub setup for RAID controllers
1180     </impo>
1181 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1182 zhen 1.6 command-line prompt. Now, you need to type in the
1183     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1184     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1185     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1186     I want to type are:
1187     </p>
1188 zhen 1.16 <pre caption="GRUB Commands">
1189 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1190     grub&gt; <c>setup (hd0)</c>
1191     grub&gt; <c>quit</c>
1192 zhen 1.6 </pre>
1193 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1194 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1195     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1196     </c> command tells GRUB where to install the
1197     boot record - it will be configured to look for its special files at the <c>root
1198     ( )</c> location that you specified. In my case, I want the boot record on the
1199     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1200     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1201     could install GRUB to the boot record of a particular partition. In that case,
1202     I'd specify a particular partition rather than the entire disk. Once the GRUB
1203     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1204    
1205     <note> The tab completion mechanism of grub can be used from within grub,
1206     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1207     be prompted with a list of the available devices (not only harddrives),
1208     hitting the TAB key having written <c> root (hd</c>, grub would print the
1209     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1210     would make grub print the list of partitions on the first harddrive.
1211    
1212     Checking the syntax of the grub location with completion should really help
1213     to make the right choice.
1214     </note>
1215    
1216     Gentoo Linux is now
1217     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1218     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1219     </p>
1220 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1221 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1222     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1223 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:
1224 zhen 1.6 </p>

1248 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1249 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1250     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).

1252 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1253 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1254     and shows you how to use GRUB to boot a bootable Windows partition.
1255     </p>
1256 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition

1261 zhen 1.16 <note>
1262 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>.
1263 zhen 1.6 </note>
1264 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1265 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1266     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1267     turn off devfs by default (not recommended unless you know what you're doing) by
1268     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1269     </p>
1270 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1271 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1272     devfs is enabled by default.

1278     <title>Final steps: Configure LILO</title>
1279     <section>
1280     <body>
1281 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1282     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1283     LILO if you would like to use it instead of GRUB:
1284 zhen 1.16 </p>
1285     <p>The first step is to emerge LILO:
1286     </p>
1287     <pre caption="Emerging LILO">
1288     # <c>emerge lilo</c>
1289     </pre>
1290     <p>Now it is time to configure LILO. I will give you a small <i>lilo.conf</i> to use, and I will explain
1291     the different parts of the file.
1292     </p>
1293     <pre caption="Example lilo.conf">

1295     map=/boot/map
1296     install=/boot/boot.b

1308    
1309     #For dual booting windows/other OS
1310     other=/dev/hda1
1311     label=dos
1312    
1313     </pre>
1314     <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
1315     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1316     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1317     In normal use, this should not be altered. If the install line is missing, LILO will
1318     assume a default of /boot/boot.b as the file to be used. </li>
1319     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1320     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1321     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1322     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1323     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1324     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1325     operating system or kernel to boot. </li>
1326     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1327     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1328     your system in an unbootable state. </li>
1329     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1330     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1331     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1332     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1333     it is also the name referred to by the default line. </li>
1334     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1335     to actually initialize and start the devices that makes booting the kernel possible. The initial
1336     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1337     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1338     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1339     altered during the boot process. </li>
1340     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1341     <note>Thanks to <uri link="http://www.redhat.com">Redhat.com</uri> for this information.
1342     </note>
1343     <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information

1358     <body>
1359 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1360 zhen 1.16 time you install any Linux distribution. This is a security
1361 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
1362     disk. With these types of hardware RAID,
1363     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1364     make a GRUB
1365     boot disk, and when you reboot the first time you can install GRUB
1366 zhen 1.6 to the MBR. Make your

1428 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1429 zhen 1.16 (there's a &quot;click to subscribe&quot; link on our <uri link="http://www.gentoo.org">main page</uri>).
1430 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>
1431     that will
1432     help you to continue configuring your new Gentoo Linux system, and a useful
1433     <uri link="http://www.gentoo.org/doc/en/portage-user.xml">Portage user guide</uri>
1434     to help familiarize you with Portage basics. You can find the rest of the Gentoo Documentation
1435 zhen 1.16 <uri link="http://www.gentoo.org/main/en/docs.xml">here</uri>. If you have any other questions
1436 zhen 1.10 involving installation or anything for that matter, please check the Gentoo Linux

1444     <title>Gentoo-Stats</title>
1445     <section>
1446     <body>
1447     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1448 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1449     us in set priorities our development. Installing it is completely optional, and it would be greatly
1450     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1451     </p>
1452 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1453 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1454     to individually identify your system, nor will it be mached against an IP address or
1455     other personal information. Every precaution has been taken to assure your privacy in the
1456     development of this system. The following are the things that we are monitoring
1457 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1458 zhen 1.6 </p>
1459 zhen 1.16 <ul>
1460     <li>installed packages and their version numbers</li>
1461     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1462     <li>memory information (total available physical RAM, total available swap space)</li>
1463     <li>PCI cards and network controller chips</li>
1464     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1465     </ul>
1466     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1467 zhen 1.6 (just as it is to the developers).
1468     </p>
1469 zhen 1.16 <ul>
1470     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1471 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1472 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1473     <li>The IP address your data transmission originates from will never be logged
1474     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1475     </ul>
1476     <p>The installation is easy - just run the following commands:
1477 zhen 1.6 </p>
1478 zhen 1.16 <pre caption="Installing gentoo-stats">
1479 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1480     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1481 zhen 1.6 </pre>
1482 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1483 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1484     to see additional configuration options.
1485     </p>
1486 zhen 1.16 <p>After that, the program should be run on a regular schedule
1487 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1488     </p>
1489 zhen 1.16 <pre caption="Updating gentoo-stats with cron">
1490     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1491     </pre>
1492     <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1493 zhen 1.6 viewed with your favortive pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
