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

35     <title>About the Install</title>
36     <section>
37     <body>
38 drobbins 1.21
39     <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
40     as many SCSI CD-ROM, assuming that your CD-ROM and BIOS both support booting.
41     Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
42     kernel) as well as support for all SCSI devices (available as modules.) In
43     addition, we provide modules for literally every kind of network card that
44     Linux supports, as well as tools to allow you to configure your network and
45     establish outbound (as well as inbound) <c>ssh</c> connections and download
46     files. </p>
47    
48     <p>To install from the build CD, you will need to have a 486+ processor and
49     ideally at least 64 Megabytes of RAM. (Gentoo linux has been successfully
50     built with 64MB of RAM + 64MB of swap space, but the build process is awfully
51     slow under those conditions.)</p>
52    
53     <p>Gentoo Linux can be installed using one of three "stage" tarball files. The
54     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    
61     <p> So, how does one beging the install process? First, you'll want to decide
62     which one of our LiveCD ISO images to grab from
63 drobbins 1.23 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc2/x86/</uri>.
64 drobbins 1.22 In this directory, you'll see several subdirectories such as <c>athlon</c>
65 drobbins 1.24 for each of our various architecture-specific builds. Here's a low-down on
66     each arch directory and what it contains:</p>
67     <table>
68     <tr><th>Architecture</th><th>Description</th></tr>
69     <tr><ti>x86</ti><ti>Stage 1 tarballs and "gentoo-basic" liveCD -- will work on anything.</ti></tr>
70     <tr><ti>i586</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for i586+ CPUs</ti></tr>
71     <tr><ti>i686</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for i686+ CPUs</ti></tr>
72     <tr><ti>athlon</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for AMD Athlon CPUs</ti></tr>
73     <tr><ti>athlon-xp</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for AMD Athlon XP CPUs</ti></tr>
74     <tr><ti>athlon-mp</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for AMD Athlon MP CPUs</ti></tr>
75     <tr><ti>pentium3</ti><ti>Stage 2 and 3 tarballs, GRP packages and liveCD for Intel Pentium III and Pentium 4 CPUs</ti></tr>
76     </table>
77    
78     <p>Inside each of these directories,
79 drobbins 1.22 you'll find a <path>livecd/</path> directory that contains LiveCDs. While these LiveCDs
80     will boot on any architecture, the install-related tarballs are optimized for a particular
81 drobbins 1.24 CPU type and will not work on all systems, except for the "gentoo-basic" LiveCD in the <path>x86</path>
82     directory which can be used to install on anything.
83 drobbins 1.22 </p>
84 drobbins 1.24
85     <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
86     using CD burning software. Currently, we have two types of LiveCDs. The first
87     carries the "gentoo-basic" label, and is approximately 40MB in size and lives
88     in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
89     allow for a initial quick download and contains a stage1 tarball that can be
90     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
91 drobbins 1.21
92     <p>The second flavor of LiveCD we currently offer is labelled "livecd-grp."
93 drobbins 1.24 These CDs (found in their respective <path>arch/livecd</path> directories)
94     contain stage1, 2 and 3 tarballs, and also contain a set of GRP packages
95     optimized for a specific architecture. Using these LiveCDs, it will be possible
96     for you to install a fully-functional Gentoo Linux system very quickly. The
97     downside is that these ISO images are large -- around 600MB -- so they can take
98     a while to download.</p>
99 drobbins 1.21
100 drobbins 1.24 <info>If for some reason your install gets interrupted at some point, you can
101     reboot and restart. For example, if you have partitioned, installed the stageX
102     tarball, and are ready to chroot, you can restart the install if necessary.
103     Just re-boot with the LiveCD, then mount your drives/partitions to
104     <path>/mnt</path> as normal. Basically, you can do this at about any point
105     during the install, just not before partitioning for obvious reasons. </info>
106 drobbins 1.21
107     <warn>If you encounter a problem with any part of the install and wish to
108     report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
109     needs to be moved upstream to the package maintainers (ie KDE) the
110     <e>developers</e> will take care of that. </warn>
111    
112     <p>Now, let's quickly review the install process. First, we'll download, burn
113     and boot a LiveCD. After getting a root prompt, we'll create partitions, create
114     our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
115     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
116     our systems to stage3. Once our systems are at stage3, we can configure them
117     (tweaking config files, installing a bootloader, etc) and boot them and have a
118     fully-functional Gentoo Linux system. Depending on what stage of the build
119     process you're starting from, here's what's required for installation: </p>

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

169     <body>
170     <p>If the PCI autodetection missed some of your hardware, you
171 zhen 1.6 will have to load the appropriate modules manually.
172     To view a list of all available network card modules, type <c>ls
173     /lib/modules/*/kernel/drivers/net/*</c>. To load a particular module,
174     type:

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

215     <body>
216     <p>If you have a PCMCIA network card, you will need to do some additional
217 zhen 1.6 trickery.
218     </p>
219 zhen 1.16 <warn>To avoid problems with <c>cardmgr</c>, you <e>must</e> run it <e>before</e> you enter the chroot

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

230 zhen 1.6 preferable. (Technically, you need not run
231 drobbins 1.21 <c>cardmgr</c> if you know exactly which module your PCMCIA card requires.
232 zhen 1.6 But if you don't, loading all PCMCIA modules and see which sticks won't work,
233     as all PCMCIA modules load obligingly and hang around for a PCMCIA card to
234 drobbins 1.21 drop by. <c>cardmgr</c> will also unload the module(s) for any card when you

259     <title> Automatic Network Configuration </title>
260     <body>
261     <p>The Gentoo Linux install lets you configure a working network, allowing you to use
262 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.
263 zhen 1.6 Even if you don't need to do these things now, you should go ahead and set up networking now.
264     Once networking is up, Portage will be able to use your configured network once you are inside
265     the chroot environment (required for installing Gentoo Linux).
266     The simplest way to set up networking is to run our new <c>net-setup</c>
267     script. </p>

275     <title>Manual DHCP Configuration</title>

282 zhen 1.16 <note>Some ISPs require you to provide a hostname. To do that,
283 zhen 1.6 add a <c>-h myhostname</c> flag to the dhcpcd command line above.
284     </note>
285 zhen 1.16 <p>If you receive <i>dhcpConfig</i> warnings, don't panic; the errors

289     <section>
290     <title>Manual Static Configuration</title>
291     <body>
292     <p>We need to setup just enough networking so that we can download
293 zhen 1.6 sources for the system build, as well as the required localhost interface.
294     Type in the following commands, replacing
295     $IFACE with your network interface (typically <c>eth0</c>), $IPNUM
296     with your IP address, $BCAST with your broadcast address, and $NMASK
297     with your network mask. For the <c>route</c> command, replace
298     $GTWAY with your default gateway.

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

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

524     <impo>If your <e>boot</e> partition (the one holding the kernel) is ReiserFS, be sure to mount it

727     <p>If you bind mounted <path>/mnt/cdrom/gentoo/packages</path> previously, you can take advantage of pre-built GRP package sets
728     to avoid compiling certain popular and large packages. Currently, we provide full builds of everything you need for <c>openoffice-bin</c>,
729     <c>gnome</c>, <c>kde</c> and <c>xfree</c>. To merge these pre-built packages, type:</p>
730     <pre caption="Using GRP">
731     # emerge --usepkgonly kde
732     </pre>
733     <p>Optionally, you can use pre-built packages combined with any updates available in your new Portage tree by typing:</p>

745     <p>At this point, you should have system that's ready for final configuration.
746     We'll start the configuration process by setting the timezone. By setting the timezone before building
747     the kernel we ensure that users get reasonable <c>uname -a</c> output.
748     </p>
749     <p>Look for your timezone (or GMT if you using Greenwich Mean Time) in
750     <path>/usr/share/zoneinfo</path>. Then, make a symbolic link by typing:
751     </p>
752     <pre caption="Creating a symbolic link for timezome">
753     # <c>ln -sf /usr/share/zoneinfo/path/to/timezonefile /etc/localtime</c>

755     <p>You might also want to check <path>/etc/rc.conf</path> to make sure your timezone settings
756     are correct.

808     If you are configuring your own kernel, be careful with the <i>grsecurity</i> option. Being too aggressive with your

810 zhen 1.6 </warn>

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

902     for a sample configuration file.
903     </warn>
904 zhen 1.16 <impo>
905 zhen 1.6 Metalog flushes output to the disk in blocks, so messages aren't immediately recorded into
906     the system logs. If you are trying to debug a daemon, this performance-enhancing behavior
907     is less than helpful. When your Gentoo Linux system is up and running, you can send
908     metalog a USR1 signal to temporarily turn off this message buffering (meaning that
909     <i>tail -f <path>/var/log/everything/current</path></i> will now work
910     in real time, as expected),
911     and a USR2 signal to turn buffering back on

1113     <title>Final steps: Configure GRUB</title>
1114     <section>
1115     <body>
1116     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1117 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1118     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1119 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1120 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1121     cdrom players, burners, and that the same construct can be used with scsi drives.
1122     (Normally they get higher numbers than ide drives except when the bios is configured
1123     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1124     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1125     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1126    
1127     It might sound tricky, and tricky it is indeed, but as we will see, grub
1128     offers a tab completion mechanism that comes handy for those of you having
1129     a lot of harddrives and partitions and who are a little lost in the
1130     grub numbering scheme. Having gotten the feel for that,
1131     it's time to install GRUB.
1132     </p>
1133 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1134     <pre caption="Installing GRUB">
1135 drobbins 1.1 # <c>grub</c>
1136 zhen 1.6 </pre>
1137 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1138 zhen 1.6 this time.
1139     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1140     grub setup for RAID controllers
1141     </impo>
1142 zhen 1.16 <p>You'll be presented with the <c>grub&gt;</c> grub
1143 zhen 1.6 command-line prompt. Now, you need to type in the
1144     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1145     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1146     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1147     I want to type are:
1148     </p>
1149 zhen 1.16 <pre caption="GRUB Commands">
1150 drobbins 1.1 grub&gt; <c>root (hd0,0)</c>
1151     grub&gt; <c>setup (hd0)</c>
1152     grub&gt; <c>quit</c>
1153 zhen 1.6 </pre>
1154 zhen 1.16 <p>Here's how the two commands work. The first <c>root ( )</c> command tells GRUB
1155 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1156     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1157     </c> command tells GRUB where to install the
1158     boot record - it will be configured to look for its special files at the <c>root
1159     ( )</c> location that you specified. In my case, I want the boot record on the
1160     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1161     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1162     could install GRUB to the boot record of a particular partition. In that case,
1163     I'd specify a particular partition rather than the entire disk. Once the GRUB
1164     boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1165    
1166     <note> The tab completion mechanism of grub can be used from within grub,
1167     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1168     be prompted with a list of the available devices (not only harddrives),
1169     hitting the TAB key having written <c> root (hd</c>, grub would print the
1170     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1171     would make grub print the list of partitions on the first harddrive.
1172    
1173     Checking the syntax of the grub location with completion should really help
1174     to make the right choice.
1175     </note>
1176    
1177     Gentoo Linux is now
1178     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1179     we get a nice GRUB boot menu when the system reboots. Here's how to do it.
1180     </p>
1181 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1182 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1183     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1184 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:
1185 zhen 1.6 </p>
1186 zhen 1.16 <pre caption="Grub.conf for GRUB">

1207     </note>
1208 zhen 1.16 <impo>
1209 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1210 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1211     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1212 zhen 1.6 </impo>
1213 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1214 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1215     and shows you how to use GRUB to boot a bootable Windows partition.
1216     </p>
1217 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1218 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
1219     your root filesystem. <path>(hd0,5)</path> contains the NT boot
1220     loader.
1221 zhware 1.9 </note>
1222 zhen 1.16 <note>
1223 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>.
1224 zhen 1.6 </note>
1225 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1226 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1227     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1228     turn off devfs by default (not recommended unless you know what you're doing) by
1229     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1230     </p>
1231 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
1232 zhen 1.6 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs. In rc6
1233     devfs is enabled by default.

1239     <title>Final steps: Configure LILO</title>
1240     <section>
1241     <body>
1242 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1243     LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here's how to install
1244     LILO if you would like to use it instead of GRUB:
1245 zhen 1.16 </p>
1246     <p>The first step is to emerge LILO:
1247     </p>
1248     <pre caption="Emerging LILO">
1249     # <c>emerge lilo</c>
1250     </pre>
1251     <p>Now it is time to configure LILO. I will give you a small <i>lilo.conf</i> to use, and I will explain
1252     the different parts of the file.
1253     </p>
1254     <pre caption="Example lilo.conf">
1255     boot=/dev/hda
1256     map=/boot/map
1257     install=/boot/boot.b
1258     prompt
1259     timeout=50
1260     message=/boot/message
1261     lba32
1262     default=linux
1263    
1264     image=/boot/vmlinuz-2.4.20
1265     label=linux
1266     initrd=/boot/initrd-2.4.20.img
1267     read-only
1268     root=/dev/hda5
1269    
1270     #For dual booting windows/other OS
1271     other=/dev/hda1
1272     label=dos
1273    
1274     </pre>
1275     <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
1276     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1277     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1278     In normal use, this should not be altered. If the install line is missing, LILO will
1279     assume a default of /boot/boot.b as the file to be used. </li>
1280     <li>The existence of <i>prompt</i> tells LILO to show you whatever is referenced in the message line.
1281     While it is not recommended that you remove the prompt line, if you do remove it, you can still
1282     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1283     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1284     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1285     <li><i>message=/boot/message</i> refers to the screen that LILO displays to let you select the
1286     operating system or kernel to boot. </li>
1287     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1288     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1289     your system in an unbootable state. </li>
1290     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1291     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1292     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1293     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1294     it is also the name referred to by the default line. </li>
1295     <li><i>initrd=/boot/initrd-2.4.20.img</i> refers to the initial ram disk image that is used at boot time
1296     to actually initialize and start the devices that makes booting the kernel possible. The initial
1297     ram disk is a collection of machine-specific drivers necessary to operate a SCSI card, hard drive, or any
1298     other device needed to load the kernel. You should never try to share initial ram disks between machines. </li>
1299     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1300     altered during the boot process. </li>
1301     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1302     <note>Thanks to <uri link="http://www.redhat.com">Redhat.com</uri> for this information.
1303     </note>
1304     <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information
1305     into the MBR:

1318     <title>GRUB Bootdisks</title>
1319     <body>
1320 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1321 zhen 1.16 time you install any Linux distribution. This is a security
1322 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
1323     disk. With these types of hardware RAID,
1324     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1325     make a GRUB
1326     boot disk, and when you reboot the first time you can install GRUB
1327 zhen 1.6 to the MBR. Make your
1328     bootdisk like this:

1363     <p>Now, Gentoo Linux is installed. The only remaining step is to exit the chrooted shell,
1364 zhen 1.6 udpate necessary configuration files,
1365     safely unmount your partitions

1379 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create

1383 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1384 zhen 1.6 use the bootdisk for the first reboot.

1404     <title>Gentoo-Stats</title>
1405     <section>
1406     <body>
1407     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1408 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1409     us in set priorities our development. Installing it is completely optional, and it would be greatly
1410     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1411     </p>
1412 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1413 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1414     to individually identify your system, nor will it be mached against an IP address or
1415     other personal information. Every precaution has been taken to assure your privacy in the
1416     development of this system. The following are the things that we are monitoring
1417 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1418 zhen 1.6 </p>
1419 zhen 1.16 <ul>
1420     <li>installed packages and their version numbers</li>
1421     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1422     <li>memory information (total available physical RAM, total available swap space)</li>
1423     <li>PCI cards and network controller chips</li>
1424     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1425     </ul>
1426     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1427 zhen 1.6 (just as it is to the developers).
1428     </p>
1429 zhen 1.16 <ul>
1430     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1431 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1432 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1433     <li>The IP address your data transmission originates from will never be logged
1434     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1435     </ul>
1436     <p>The installation is easy - just run the following commands:
1437 zhen 1.6 </p>
1438 zhen 1.16 <pre caption="Installing gentoo-stats">
1439 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
