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

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:
420     </p>

444     <ti>/dev/hda3</ti>
445     </tr>
446     </table>
447 drobbins 1.21 <p>Before creating filesystems, you may want to initialize the
448     beginning of your HD using <c>dd</c>. Doing this will ensure that your new filesystem
449     will not be mis-indentified by Linux's mounting code.
450     This can be done as follows:
451 zhen 1.6 </p>
452 zhen 1.16 <pre caption="Initializing first 1024 Sectors of HD">
453 zhen 1.34 # <c>dd if=/dev/zero of=/dev/hdxy bs=1K count=1</c>
454 zhen 1.26 <comment>Replace /dev/hdxy with the device you wish to &quot;clean.&quot;</comment>
455 zhen 1.6 </pre>
456 zhware 1.43 <warn>The command above will destroy all data from <path>/dev/hdxy</path>.
457     Be careful and check twice which partition you specify for zeroing.
458     If you make a mistake it might result in a loss of data.
459     </warn>
460 drobbins 1.21 <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
461     should be of type 82 if swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
462     <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
463     <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>
464 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
465 drobbins 1.21 new partition configuration.</note>
466 zhen 1.26 <note>If you are using RAID your partitions will be a little different. You
467 drobbins 1.21 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X is
468     the arrays you have made, so if you only have made 1 array, then it will be
469     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
470 zhen 1.26 <p>Once you've created your partitions, it's time to initialize
471 zhen 1.6 the filesystems that will be used to house our data. Initialize swap as follows:</p>
472 zhen 1.16 <pre caption="Initializing Swap">
473 drobbins 1.1 # <c>mkswap /dev/hda2</c>
474 zhen 1.6 </pre>
475 zhen 1.16 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems.</p>
476     <pre caption="Creating an ext2 Filesystem">
477 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
478 zhen 1.6 </pre>
479 zhen 1.16 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command.</p>
480     <pre caption="Creating a XFS Filesystem">
481 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
482 zhen 1.6 </pre>
483 zhen 1.16 <note>
484 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>.
485     The <c>-d agcount=3</c> command will lower
486     the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition,
487     so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5.
488     The <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing performance.
489     </note>
490 zhen 1.16 <warn>
491 zhen 1.6 If you are installing an XFS partition over a previous ReiserFS partition,
492     later attempts to mount may fail without an explicit <c>mount -t xfs</c>.
493     The solution is to zero out the partition before creating the XFS filesystem:
494     <c>dd if=/dev/zero of=/dev/hd<comment>x</comment> bs=1k</c>.
495     </warn>
496 zhen 1.16 <p>If you'd like to use ext3, you can create ext3 filesystems using <c>mke2fs -j</c>.</p>

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

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

1195 zhen 1.49 <title>Configuring GRUB</title>
1196 zhen 1.16 <body>
1197     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1198 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1199     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1200 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1201 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1202     cdrom players, burners, and that the same construct can be used with scsi drives.
1203     (Normally they get higher numbers than ide drives except when the bios is configured
1204     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1205     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1206     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1208     It might sound tricky, and tricky it is indeed, but as we will see, grub
1209     offers a tab completion mechanism that comes handy for those of you having
1210     a lot of harddrives and partitions and who are a little lost in the
1211     grub numbering scheme. Having gotten the feel for that,
1212     it's time to install GRUB.
1213     </p>
1214 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1215     <pre caption="Installing GRUB">
1216 zhen 1.51 # <c>emerge grub</c>
1217 drobbins 1.1 # <c>grub</c>
1218 zhen 1.6 </pre>
1219 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1220 zhen 1.6 this time.
1221     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1222     grub setup for RAID controllers
1223     </impo>
1224 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1225 zhen 1.6 command-line prompt. Now, you need to type in the
1226     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1227     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1228     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1229     I want to type are:
1230     </p>
1231 zhen 1.16 <pre caption="GRUB Commands">
1232 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1233     grub&gt; <c>setup (hd0)</c>
1234 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
1235     grub&gt; <c>setup (hd0) (hd0,4) </c>
1236     <codenote>The second parameter above identifies the boot partition</codenote>
1237 drobbins 1.1 grub&gt; <c>quit</c>
1238 zhen 1.6 </pre>
1239 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1240 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1241     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1242     </c> command tells GRUB where to install the
1243     boot record - it will be configured to look for its special files at the <c>root
1244     ( )</c> location that you specified. In my case, I want the boot record on the
1245     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1246     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1247     could install GRUB to the boot record of a particular partition. In that case,
1248     I'd specify a particular partition rather than the entire disk. Once the GRUB
1249     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1250 zhen 1.52 </p>
1251 zhen 1.6
1252     <note> The tab completion mechanism of grub can be used from within grub,
1253     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1254     be prompted with a list of the available devices (not only harddrives),
1255     hitting the TAB key having written <c> root (hd</c>, grub would print the
1256     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1257     would make grub print the list of partitions on the first harddrive.
1259     Checking the syntax of the grub location with completion should really help
1260     to make the right choice.
1261     </note>
1263 zhen 1.52 <p>
1264 zhen 1.6 Gentoo Linux is now
1265     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1266     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1267     </p>
1268 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1269 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1270     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1271 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:

1295 zhen 1.16 <impo>
1296 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1297 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1298     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1299 zhen 1.6 </impo>
1300 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1301 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1302     and shows you how to use GRUB to boot a bootable Windows partition.
1303     </p>
1304 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1305 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1306     your root filesystem. <path>(hd0,5)</path> contains the NT boot
1307     loader.
1308 zhware 1.9 </note>
1309 zhen 1.16 <note>
1310 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>.
1311 zhen 1.6 </note>
1312 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1313 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1314     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1315     turn off devfs by default (not recommended unless you know what you're doing) by
1316     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1317     </p>
1318 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1319 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1320     devfs is enabled by default.

1325     <title>Configuring LILO</title>
1326 zhen 1.16 <body>
1327 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1328     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1329     LILO if you would like to use it instead of GRUB:
1330 zhen 1.16 </p>
1331     <p>The first step is to emerge LILO:
1332     </p>
1333     <pre caption="Emerging LILO">

1336     <p>Now it is time to configure LILO. I will give you a small <i>lilo.conf</i> to use, and I will explain
1337     the different parts of the file.
1338     </p>
1339     <pre caption="Example lilo.conf">

1341     map=/boot/map
1342     install=/boot/boot.b

1355     #For dual booting windows/other OS
1356     other=/dev/hda1
1357     label=dos
1359     </pre>
1360 zhen 1.52 <ul>
1361 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>
1362     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1363     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1364     In normal use, this should not be altered. If the install line is missing, LILO will
1365     assume a default of /boot/boot.b as the file to be used. </li>
1366     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1367     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1368     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1369     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1370     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1371     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1372     operating system or kernel to boot. </li>
1373     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1374     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1375     your system in an unbootable state. </li>
1376     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1377     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1378     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1379     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1380     it is also the name referred to by the default line. </li>
1381     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1382     to actually initialize and start the devices that makes booting the kernel possible. The initial
1383     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1384     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1385     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1386     altered during the boot process. </li>
1387     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>

1406     <body>
1407 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1408 zhen 1.16 time you install any Linux distribution. This is a security
1409 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
1410     disk. With these types of hardware RAID,
1411     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1412     make a GRUB
1413     boot disk, and when you reboot the first time you can install GRUB
1414 zhen 1.6 to the MBR. Make your
1415     bootdisk like this:
1416     </p>
1417 zhen 1.16 <pre caption="Creating a GRUB Bootdisk">

1437     <p>If you are using LILO, it is also a good idea to make a bootdisk:

1439 zhen 1.18 <pre caption="Making a LILO Bootdisk">
1440     # <c>dd if=/boot/your_kernel of=/dev/fd0 </c>
1441     <comment>This will only work if your kernel is smaller than 1.4MB</comment>

1450     <p>Now, Gentoo Linux is installed. The only remaining step is to exit the chrooted shell,
1451 zhen 1.6 udpate necessary configuration files,
1452     safely unmount your partitions
1453     and reboot the system:
1454     </p>
1455 zhen 1.16 <pre caption="Rebooting the System">
1456 drobbins 1.1 # <c>etc-update</c>
1457     # <c>exit</c>
1458     <codenote>This exits the chrooted shell; you can also type <c>^D</c></codenote>
1459     # <c>cd / </c>
1460     # <c>umount /mnt/gentoo/boot</c>
1461     # <c>umount /mnt/gentoo/proc</c>
1462 drobbins 1.36 # <c>umount /mnt/gentoo/dev</c>
1463 drobbins 1.1 # <c>umount /mnt/gentoo</c>
1464     # <c>reboot</c>
1465 zhen 1.6 </pre>
1466 zhen 1.16 <note>
1467 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1468     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1469     generally make changes to the files in <path>/etc/modules.d</path>.
1470     </note>
1471 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1472 zhen 1.6 use the bootdisk for the first reboot.
1473     then go back and install grub the way everyone else did the first
1474 drobbins 1.21 time. You are done -- congratulations!</impo>
1475 zhen 1.16 <p>If you have any questions or would like to get involved with Gentoo Linux development,
1476 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1477 zhen 1.16 (there's a &quot;click to subscribe&quot; link on our <uri link="http://www.gentoo.org">main page</uri>).
1478 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>
1479     that will
1480     help you to continue configuring your new Gentoo Linux system, and a useful
1481     <uri link="http://www.gentoo.org/doc/en/portage-user.xml">Portage user guide</uri>
1482     to help familiarize you with Portage basics. You can find the rest of the Gentoo Documentation

1492     <title>Gentoo-Stats</title>
1493     <section>
1494     <body>
1495     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1496 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1497     us in set priorities our development. Installing it is completely optional, and it would be greatly
1498     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1499     </p>
1500 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1501 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1502     to individually identify your system, nor will it be mached against an IP address or
1503     other personal information. Every precaution has been taken to assure your privacy in the
1504     development of this system. The following are the things that we are monitoring
1505 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1506 zhen 1.6 </p>
1507 zhen 1.16 <ul>
1508     <li>installed packages and their version numbers</li>
1509     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1510     <li>memory information (total available physical RAM, total available swap space)</li>
1511     <li>PCI cards and network controller chips</li>
1512     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1513     </ul>
1514     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1515 zhen 1.6 (just as it is to the developers).
1516     </p>
1517 zhen 1.16 <ul>
1518     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1519 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1520 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1521     <li>The IP address your data transmission originates from will never be logged
1522     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1523     </ul>
1524     <p>The installation is easy - just run the following commands:
1525 zhen 1.6 </p>
1526 zhen 1.16 <pre caption="Installing gentoo-stats">
1527 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1528     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1529 zhen 1.6 </pre>
1530 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1531 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1532     to see additional configuration options.
1533     </p>
1534 zhen 1.16 <p>After that, the program should be run on a regular schedule
1535 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1536     </p>
1537 zhen 1.16 <pre caption="Updating gentoo-stats with cron">
1538     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1539     </pre>
1540     <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1541 zhen 1.6 viewed with your favortive pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
