39 zhen 1.16 <abstract>These instructions step you through the process of installing Gentoo
40 jhhudso 1.74 Linux 1.4_rc3. The Gentoo Linux installation process supports various installation
41 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
42     scratch.

47     <title>About the Install</title>
48     <section>
49     <body>
50 zhen 1.26 <p>This new boot CD will boot from nearly any modern IDE CD-ROM drive, as well
51 jhhudso 1.71 as many SCSI CD-ROM drives, assuming that your CD-ROM and BIOS both support booting.
52 drobbins 1.21 Included on the CD-ROM is Linux support for IDE (and PCI IDE) (built-in to the
53     kernel) as well as support for all SCSI devices (available as modules.) In
54     addition, we provide modules for literally every kind of network card that
55     Linux supports, as well as tools to allow you to configure your network and
56 jhhudso 1.75 establish outbound (as well as inbound) <c>ssh</c> connections and to download
57 drobbins 1.21 files. </p>
58 zhen 1.26 <p>To install from the build CD, you will need to have a 486+ processor and
59 drobbins 1.69 ideally at least 64 Megabytes of RAM. (Gentoo Linux has been successfully
60 drobbins 1.21 built with 64MB of RAM + 64MB of swap space, but the build process is awfully
61     slow under those conditions.)</p>
62 zhen 1.26 <p>Gentoo Linux can be installed using one of three &quot;stage&quot; tarball files. The
63 drobbins 1.21 one you choose depends on how much of the system you want to compile yourself.
64 jhhudso 1.75 The stage1 tarball is used when you want to bootstrap and build the entire
65 drobbins 1.21 system from scratch. The stage2 tarball is used for building the entire system
66 jhhudso 1.75 from a bootstrapped state. The stage3 tarball already contains a basic Gentoo Linux system.</p>
67 drobbins 1.70 <p><b>So, should you choose to start from a stage1, stage2, or stage3 tarball?</b>
68     Starting from a stage1 allows you to have total control over the optimization settings
69     and optional build-time functionality that is initially enabled on your system. This
70 jhhudso 1.75 makes stage1 installs good for power users who know what they are doing. Stage2 installs
71     allow you to skip the bootstrap process, and doing this is fine if you are happy with
72 drobbins 1.70 the optimization settings that we chose for your particular stage2 tarball. Choosing to
73     go with a stage3 allows for the fastest install of Gentoo Linux, but also means that
74 jhhudso 1.75 your base system will have the optimization settings that we chose for you. Since major
75     releases of Gentoo Linux have stage3's specifically optimized for various popular processors,
76     this may be sufficient for you. <b>If you're installing Gentoo Linux for the first time, consider
77 drobbins 1.70 using a stage3 tarball for installation.</b></p>
80 jhhudso 1.75 <p> So, how does one begin the install process? First, you will want to decide which one of our LiveCD ISO images to grab from
81 jhhudso 1.74 <uri>http://www.ibiblio.org/gentoo/releases/1.4_rc3/x86/</uri> .
82 drobbins 1.22 </p>
83 zhen 1.26 <p> The LiveCDs are full CD images that should be burned to a CDR or CD-RW
84 jhhudso 1.75 using CD burning software. Currently, we have two types of LiveCDs. The first
85     carries the &quot;gentoo-basic&quot; label, and is approximately 40MB in size, contains only the stage 1 tarball and lives
86 drobbins 1.24 in the <path>x86/livecd/</path> directory. This LiveCD is of minimal size to
87     allow for a initial quick download and contains a stage1 tarball that can be
88     found in <path>/mnt/cdrom/gentoo/</path> after the CD has booted.</p>
89 seemant 1.78 <p>The second flavor of LiveCD we currently offer is labeled &quot;gentoo-3stages.&quot;
90 jhhudso 1.75 This CD is also found in <path>x86/livecd</path>. It
91 jhhudso 1.77 contains stage 1, 2 and 3 tarballs. Using this LiveCD, it will be possible
92 jhhudso 1.75 for you to install a fully-functional Gentoo Linux system very quickly.</p>
93 jhhudso 1.77 <p><b>What happened to i686, pentium3, athlon, athlon-mp stages, LiveCDs and GRP (Gentoo Reference Platform)?</b>
94 seemant 1.78 Gentoo 1.4_rc3 is meant to be a minimal release candidate only. 1.4_rc4 will contain all the usual x86 architectures and GRP. If you want to install stages optimized for these other x86 architectures or GRP, use the 1.4_rc2 documentation, which can be found at <uri>http://www.gentoo.org/doc/en/gentoo-x86-1.4_rc2-install.xml</uri>
95 jhhudso 1.77 </p>
96 drobbins 1.70 <impo>If you encounter a problem with any part of the install and wish to
97 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
98 jhhudso 1.75 needs to be sent upstream to the original software developers (eg the KDE team) the
99 drobbins 1.70 <e>Gentoo Linux developers</e> will take care of that for you.
100     </impo>
101 jhhudso 1.75 <p>Now, let us quickly review the install process. First, we will download, burn
102     and boot a LiveCD. After getting a root prompt, we will create partitions, create
103 drobbins 1.21 our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
104     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
105 jhhudso 1.75 our system to stage3. Once our system is at stage3, we can configure it
106 seemant 1.78 (customize configuration files, install a boot loader, etc) and boot it and have a
107 drobbins 1.21 fully-functional Gentoo Linux system. Depending on what stage of the build
108 jhhudso 1.75 process you're starting from, here is what is required for installation: </p>

131     <title>Booting</title>
132     <section>
133     <body>
134 jhhudso 1.75 <p>Start by booting the LiveCD. You should see a fancy boot screen
135 drobbins 1.21 with the Gentoo Linux logo on it. At this screen, you can hit Enter to begin the boot process,
136 drobbins 1.70 or boot the LiveCD with custom boot options by typing <c>gentoo opt1 opt2</c> and then hitting Enter. To see
137     a detailed description of available boot options, press F2 to view the help screen.</p>
139 jhhudso 1.75 <p> Once you hit Enter, you will be greeted with the standard kernel
140     booting output, kernel and initrd messages, followed by the normal Gentoo
141     Linux boot sequence. You will be automatically logged in as
142     &quot;<c>root</c>&quot; and the root password will be set to a random string
143     for security purposes. You should have a root (&quot;<c>#</c>&quot;) prompt
144 seemant 1.78 on the current console, and can also switch to other consoles by pressing
145 jhhudso 1.75 Alt-F2, Alt-F3 and Alt-F4. Get back to the one you started on by pressing
146     Alt-F1. At this point you should set the root password, type passwd and
147     follow the prompts.
148 zhen 1.6 </p>
149 zhen 1.26 <p>You've probably also noticed that above your <c>#</c> prompt is a bunch of help text
150 drobbins 1.70 that explains how to do things like configure your Linux networking and telling you where you can find
151 drobbins 1.21 the Gentoo Linux stage tarballs and packages on your CD.

375 zhen 1.16 <title>Partition Configuration</title>
376     <section>
377     <body>
378 jhhudso 1.75 <p>Now that the kernel can see the network card and disk controllers, it is time
379 zhen 1.6 to set up disk partitions for Gentoo Linux.
380     </p>
381 drobbins 1.70
382 jhhudso 1.75 <p>Here is a quick overview of the standard Gentoo Linux partition layout.
383 zhen 1.6 We're going to create at least three partitions: a swap partition, a root
384     partition (to hold the bulk of Gentoo Linux), and a special boot partition.
385 jhhudso 1.75 The boot partition is designed to hold the boot loader information as well as
386 zhen 1.6 your Linux kernel(s). The boot partition gives us a safe place to store
387     everything related to booting Linux. During normal day-to-day Gentoo Linux use,
388 jhhudso 1.81 your boot partition should remain <e>unmounted</e>. A working kernel will enable you to recover from most forms of
389     filesystem corruption. Having your kernel in a non-mounted partition
390 jhhudso 1.75 will prevent filesystem corruption from affecting it.
391 zhen 1.6 </p>
392 zhen 1.50 <p>Now, on to filesystem types. Right now, you have five filesystem options:
393 jhhudso 1.81 XFS, ext2, ext3 (ext2 with journaling), jfs, and ReiserFS. ext2 is the tried and true Linux
394 zhen 1.6 filesystem but doesn't have metadata journaling. ext3 is the new version of
395     ext2 with both metadata journaling and ordered data writes, effectively
396     providing data journaling as well. ReiserFS is a B*-tree based filesystem
397     that has very good small file performance, and greatly outperforms both ext2 and
398     ext3 when dealing with small files (files less than 4k), often by a factor of
399     10x-15x. ReiserFS also scales extremely well and has metadata journaling.
400     As of kernel 2.4.18+, ReiserFS is finally rock-solid and highly recommended.
401     XFS is a filesystem with metadata journaling that
402 drobbins 1.21 is fully supported under Gentoo Linux's <path>xfs-sources</path> kernel, but
403     is generally not recommended due to its tendency to lose recently-modified
404 jhhudso 1.75 data if your system locks up or unexpectedly reboots (as a result of power failure, for instance)
405     Finally, jfs is IBM's own high performance journaling filesystem. Since it is obscure, we cannot comment either positively nor negatively on its stability.</p>
406 zhen 1.16 <p>If you're looking for the most standard filesystem, use ext2. If you're looking
407 jhhudso 1.75 for the most rugged journaling filesystem, use ext3. If you're looking for a
408 zhen 1.6 high-performance filesystem with journaling support, use ReiserFS; both ext3 and ReiserFS are
409 drobbins 1.21 mature and refined.
410 zhen 1.6 Here are our basic recommended filesystem
411     sizes and types:
412     </p>
413 zhen 1.16 <table>
414     <tr>

416     <th>Size</th>
417     <th>Type</th>
418     <th>example device</th>
419     </tr>
420     <tr>
421     <ti>boot partition, containing kernel(s) and boot information</ti>
422     <ti>100 Megabytes</ti>
423     <ti>ext2/3 highly recommended (easiest); if ReiserFS then mount with <c>-o notail</c></ti>

429 drobbins 1.70 in your system.</ti>

432     </tr>
433     <tr>
434     <ti>root partition, containing main filesystem (/usr, /home, etc)</ti>
435     <ti>&gt;=1.5 Gigabytes</ti>
436     <ti>ReiserFS, ext3 recommended; ext2 ok</ti>
437     <ti>/dev/hda3</ti>
438     </tr>
439     </table>
440 zhen 1.54
441 drobbins 1.70
442     <p>At this point, create your partitions using <c>fdisk</c>. Note that your partitions
443 jhhudso 1.75 should be of type 82 for swap and 83 for regular filesystems (whether ReiserFS, ext2/3 or other). </p>
444 drobbins 1.70 <note><c>cfdisk</c> is included on the install CD, and it is <i>considerably</i> easier to use than
445     <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>
446     <note>If <c>fdisk</c> or <c>cfdisk</c> instruct you to do so, please reboot to allow your system to detect the
447     new partition configuration.</note>
448     <note>If you are using RAID your partitions will be a little different. You
449 jhhudso 1.75 will have the partitions like this: <path>/dev/ataraid/discX/partY</path> X are
450 drobbins 1.70 the arrays you have made, so if you only have made 1 array, then it will be
451     disc0.Y is the partition number as in <path>/dev/hdaY</path> </note>
452 jhhudso 1.75 <p>Once you've created your partitions, it is time to initialize
453     the filesystems that will be used to house your data.</p>
454 drobbins 1.70
455     <p>But before creating filesystems, you may want to initialize the
456 jhhudso 1.81 beginning of your partition using <c>dd</c> if you are using a pre-existing partition that has been used before.
457 drobbins 1.70 This is particularly helpful when you're going to create a new XFS filesystem on a partition that previously contained
458     a ReiserFS filesystem. Doing this will ensure that your new filesystem
459 seemant 1.78 will not be mis-identified by Linux's filesystem auto-detection code.
460 drobbins 1.21 This can be done as follows:
461 zhen 1.6 </p>
462 jhhudso 1.81 <pre caption="Initializing first 1024 bytes of your partition">
463     # <c>dd if=/dev/zero of=/dev/hda3 bs=1k count=1</c>
464     <comment>(Replace /dev/hda3 with the partition you wish to &quot;clean.&quot;)</comment>
465     </pre>
466     <warn>The command above will destroy all data from <path>/dev/hda3</path>.
467 zhware 1.43 Be careful and check twice which partition you specify for zeroing.
468     If you make a mistake it might result in a loss of data.
469     </warn>
470 drobbins 1.70 <p>Now, initialize your swap partition as follows:</p>
471 jhhudso 1.81 <pre caption="Initializing Swap">
472 drobbins 1.1 # <c>mkswap /dev/hda2</c>
473 jhhudso 1.81 </pre>
474 zhen 1.16 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems.</p>
475 jhhudso 1.81 <pre caption="Creating an ext2 Filesystem">
476 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
477 jhhudso 1.81 </pre>
478 zhen 1.16 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command.</p>
479 jhhudso 1.81 <pre caption="Creating a XFS Filesystem">
480 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
481 jhhudso 1.81 </pre>
482     <note>You may want to add a couple of additional flags to the
483     <c>mkfs.xfs</c> command: <c>-d agcount=3 -l size=32m</c>.
484     The <c>-d agcount=3</c> command will lower the number of allocation groups.
485     XFS will insist on using at least 1 allocation group per 4 GB of your
486     partition, so, for example, if you have a 20 GB partition you will need
487     a minimum agcount of 5. The <c>-l size=32m</c> command increases the
488     journal size to 32 Mb, increasing performance.</note>
489     <p>If you would like to use ext3, you can create ext3 filesystems using
490     <c>mke2fs -j</c>.</p>
491     <pre caption="Creating an ext3 Filesystem">

635 drobbins 1.70 on your Gentoo Linux system. First
636 zhen 1.6 edit the file <path>/etc/make.conf</path>. In this file, you should set your

638 drobbins 1.70 like to be built into packages if available; generally, the defaults (an <e>empty</e>

883 zhen 1.16 <p>If you are using hardware RAID you will need to enable a couple more options in the kernel:
884 zhen 1.6 For Highpoint RAID controllers select hpt366 chipset support, support for IDE RAID controllers and Highpoint
885     370 software RAID.For Promise RAID controllers select PROMISE PDC202{46|62|65|67|68|69|70} support,
886     support for IDE RAID
887     controllers and Support Promise software RAID (Fasttrak(tm))
888     </p>
889 zhen 1.16 <p>If you use PPPoE to connect to Internet, you will need the following
890 zhen 1.6 options in the kernel (built-in or as preferably as modules) :
891 zhen 1.16 &quot;PPP (point-to-point protocol) support&quot;, &quot;PPP support for async serial ports&quot;,
892     &quot;PPP support for sync tty ports&quot;. The two compression options won't harm but
893     are not definitely needed, neither does the &quot;PPP over Ethernet&quot; option,
894 zhen 1.6 that might only be used by <i>rp-pppoe</i> when configured to do kernel mode PPPoE.
895     </p>
896 zhen 1.16 <p>If you have an IDE cd burner, then you need to enable SCSI emulation in the
897     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA and ATAPI Block
898     devices&quot; ---&gt; &quot;SCSI emulation support&quot; (I usually make it a module), then
899     under &quot;SCSI support&quot; enable &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and
900     &quot;SCSI generic support&quot; (again, I usually compile them as modules). If you
901     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
902     &gt;&gt; /etc/modules.autoload</c> to have them automatically added at boot time.

904 zhen 1.16 <note>
905 zhen 1.6 For those who prefer it,
906     it is now possible to install Gentoo Linux with a 2.2 kernel.
907 drobbins 1.21 However, doing this comes at a price:
908 zhen 1.6 you will lose many of the nifty features that
909     are new to the 2.4 series kernels (such as XFS and tmpfs
910     filesystems, iptables, and more), although the 2.2 kernel sources can be
911 drobbins 1.21 patched with ReiserFS and devfs support.
912     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
913 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
914     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel
915     line in <path>/boot/grub/grub.conf</path> for the 2.2 kernel so that a ramdisk is mounted
916 jhhudso 1.75 for the boot scripts instead of tmpfs. If you choose not to use devfs, then
917 zhen 1.6 <e>gentoo=notmpfs,nodevfs</e> should be used instead.
918     </note>
919 zhen 1.16 <p>Your new custom kernel (and modules) are now installed. Now you need to choose a system
920 zhen 1.6 logger that you would like to install. We offer sysklogd, which is the traditional set
921     of system logging daemons. We also have msyslog and syslog-ng as well as metalog. Power users seem
922     to gravitate away from sysklogd (not very good performance) and towards the
923     newer alternatives.
924     If in doubt, you may want to try metalog, since it seems to be quite popular.
925     To merge your logger of choice, type <e>one</e> of the next four lines:

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

1170     <p> In the spirit of Gentoo, users now have more than one bootloader to choose from.
1171     Using our virtual package system, users are now able to choose between both GRUB and
1172     LILO as their bootloaders.
1173     </p>
1174     <p> Please keep in mind that having both bootloaders installed is not necessary.
1175 jhhudso 1.75 In fact, it can be a hindrance, so please only choose one.
1176 zhen 1.49 </p>
1177 drobbins 1.69 <impo>If you are installing Gentoo Linux on a system with an NVIDIA nForce or nForce2 chipset
1178     with an integrated GeForce graphics card, you should use LILO and avoid GRUB. With on-board
1179 drobbins 1.70 video enabled, the low memory area of your RAM may be used as video RAM. Since GRUB also uses low
1180     memory at boot time, it may experience an "out of memory" condition. So, if you have an nForce
1181 drobbins 1.69 or potentially other board with on-board video, use LILO. Even if you're using off-board video
1182 jhhudso 1.75 right now, it would be nice to be able to remove the graphics card and use the on-board video in a
1183 drobbins 1.69 pinch, wouldn't it? :)</impo>
1185 zhen 1.49 </body>
1186     </section>
1187 zhen 1.16 <section>
1188 zhen 1.49 <title>Configuring GRUB</title>
1189 zhen 1.16 <body>
1190     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
1191 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
1192     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
1193 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
1194 zhen 1.6 Be aware too that with the hd devices, only harddrives are counted, not atapi-ide devices such as
1195     cdrom players, burners, and that the same construct can be used with scsi drives.
1196     (Normally they get higher numbers than ide drives except when the bios is configured
1197     to boot from scsi devices.) Assuming you have a harddrive on /dev/hda, a cdrom player on /dev/hdb,
1198     a burner on /dev/hdc and a second hardrive on /dev/hdd, for example, and no scsi harddrive
1199     <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
1201     It might sound tricky, and tricky it is indeed, but as we will see, grub
1202     offers a tab completion mechanism that comes handy for those of you having
1203     a lot of harddrives and partitions and who are a little lost in the
1204     grub numbering scheme. Having gotten the feel for that,
1205 jhhudso 1.75 it is time to install GRUB.
1206 zhen 1.6 </p>
1207 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
1208 jhhudso 1.81 <pre caption="Installing GRUB">
1209 zhen 1.51 # <c>emerge grub</c>
1210 drobbins 1.1 # <c>grub</c>
1211 jhhudso 1.81 </pre>
1212 zhen 1.16 <impo>If you are using hardware RAID this part will not work at
1213 zhen 1.6 this time.
1214     Skip to the section on making your <path>grub.conf</path>. After that we will complete the
1215     grub setup for RAID controllers
1216     </impo>
1217 jhhudso 1.75 <p>You will be presented with the <c>grub&gt;</c> grub
1218 zhen 1.6 command-line prompt. Now, you need to type in the
1219     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
1220     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
1221     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
1222     I want to type are:
1223     </p>
1224 zhen 1.68
1225 jhhudso 1.81 <pre caption="GRUB on the MBR">
1226 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>

1228 jhhudso 1.81 </pre>
1229 zhen 1.68
1230 jhhudso 1.81 <pre caption="GRUB not on the MBR">
1231 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
1232 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
1233     grub&gt; <c>setup (hd0,4)</c> <codenote>Where the boot record is installed, here it is /dev/hda5</codenote>
1234 drobbins 1.1 grub&gt; <c>quit</c>
1235 jhhudso 1.81 </pre>
1236 zhen 1.68
1237 jhhudso 1.75 <p>Here is how the two commands work. The first <c>root ( )</c> command tells GRUB
1238 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
1239     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
1240     </c> command tells GRUB where to install the
1241     boot record - it will be configured to look for its special files at the <c>root
1242     ( )</c> location that you specified. In my case, I want the boot record on the
1243     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
1244     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
1245     could install GRUB to the boot record of a particular partition. In that case,
1246 jhhudso 1.75 I would specify a particular partition rather than the entire disk. Once the GRUB
1247 zhen 1.6 boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
1248 zhen 1.52 </p>
1249 zhen 1.6
1250     <note> The tab completion mechanism of grub can be used from within grub,
1251     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
1252     be prompted with a list of the available devices (not only harddrives),
1253     hitting the TAB key having written <c> root (hd</c>, grub would print the
1254     available harddrives and hitting the TAB key after writing <c> root (hd0,</c>
1255     would make grub print the list of partitions on the first harddrive.
1257     Checking the syntax of the grub location with completion should really help
1258     to make the right choice.
1259     </note>
1261 zhen 1.52 <p>
1262 zhen 1.6 Gentoo Linux is now
1263     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
1264 jhhudso 1.75 we get a nice GRUB boot menu when the system reboots. Here is how to do it.
1265 zhen 1.6 </p>
1266 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from
1267 zhen 1.6 <i>grub.conf</i> to <i>menu.lst</i>. You can do this by doing
1268     <c>ln -s /boot/grub/grub.conf /boot/grub/menu.lst </c>. </impo>
1269 zhen 1.16 <p>Now, create the grub.conf file (<c>nano -w /boot/grub/grub.conf</c>), and add the following to it:

1292     </note>
1293 zhen 1.16 <impo>
1294 zhen 1.6 If you set up scsi emulation for an IDE cd burner earlier, then to get it to
1295 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
1296     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
1297 zhen 1.6 </impo>
1298 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
1299 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
1300     and shows you how to use GRUB to boot a bootable Windows partition.
1301     </p>
1302 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
1303 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to

1306 zhware 1.9 </note>
1307 zhen 1.16 <note>
1308 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>.
1309 zhen 1.6 </note>
1310 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
1311 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
1312     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
1313     turn off devfs by default (not recommended unless you know what you're doing) by
1314     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
1315     </p>
1316 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add

1323     <title>Configuring LILO</title>
1324 zhen 1.16 <body>
1325 drobbins 1.21 <p>While GRUB may be the new alternative for most people, it is not always the best choice.
1326 jhhudso 1.75 LILO, the LInuxLOader, is the tried and true workhorse of Linux bootloaders. Here is how to install
1327 drobbins 1.21 LILO if you would like to use it instead of GRUB:
1328 zhen 1.16 </p>
1329     <p>The first step is to emerge LILO:

1353 jhhudso 1.81 </pre>
1354 zhen 1.52 <ul>
1355 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>
1356     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
1357     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
1358     In normal use, this should not be altered. If the install line is missing, LILO will
1359     assume a default of /boot/boot.b as the file to be used. </li>
1360 zhen 1.82 <li>The existence of <i>prompt</i> tells LILO to show you the classic <i>lilo:</i> line at bootup.
1361 zhen 1.16 While it is not recommended that you remove the prompt line, if you do remove it, you can still
1362     get a prompt by holding down the [Shift] key while your machine starts to boot. </li>
1363     <li><i>timeout=50</i> sets the amount of time that LILO will wait for user input before proceeding
1364     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
1365     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should
1366     not change this line unless you are very aware of what you are doing. Otherwise, you could put
1367     your system in an unbootable state. </li>
1368     <li><i>default=linux</i> refers to the default operating system for LILO to boot from the
1369     options listed below this line. The name linux refers to the label line below in each of the boot options. </li>
1370     <li><i>image=/boot/vmlinuz-2.4.20</i> specifies the linux kernel to boot with this particular boot option. </li>
1371     <li><i>label=linux</i> names the operating system option in the LILO screen. In this case,
1372     it is also the name referred to by the default line. </li>
1373     <li><i>read-only</i> specifies that the root partition (see the root line below) is read-only and cannot be
1374     altered during the boot process. </li>
1375     <li><i>root=/dev/hda5</i> tells LILO what disk partition to use as the root partition. </li>
1376 zhen 1.52 </ul>
1377 zhen 1.16 <p>After you have edited your <i>lilo.conf</i> file, it is time to run LILO to load the information

1393 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
1394 zhen 1.16 time you install any Linux distribution. This is a security
1395 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
1396     disk. With these types of hardware RAID,
1397     if you try to install grub from your chrooted shell it will fail. If you are in this camp,
1398     make a GRUB
1399     boot disk, and when you reboot the first time you can install GRUB
1400 zhen 1.6 to the MBR. Make your
1401 jhhudso 1.75 bootdisks like this:

1435     <body>
1436 jhhudso 1.75 <p>Now, Gentoo Linux is installed. The only remaining step is to update necessary configuration files, exit the chrooted shell,
1438 zhen 1.6 safely unmount your partitions
1439     and reboot the system:
1440     </p>
1441 jhhudso 1.81 <pre caption="Rebooting the System">
1442 drobbins 1.1 # <c>etc-update</c>
1443     # <c>exit</c>
1444 jhhudso 1.81 <comment>(This exits the chrooted shell; you can also type <c>^D</c>)</comment>
1445 drobbins 1.1 # <c>cd / </c>
1446     # <c>umount /mnt/gentoo/boot</c>
1447     # <c>umount /mnt/gentoo/proc</c>
1448     # <c>umount /mnt/gentoo</c>
1449     # <c>reboot</c>
1450 jhhudso 1.81 </pre>
1451 zhen 1.16 <note>
1452 zhen 1.6 After rebooting, it is a good idea to run the <c>update-modules</c> command to create
1453     the <path>/etc/modules.conf</path> file. Instead of modifying this file directly, you should
1454     generally make changes to the files in <path>/etc/modules.d</path>.
1455     </note>
1456 zhen 1.16 <impo>Remember if you are running hardware RAID, you must
1457 zhen 1.6 use the bootdisk for the first reboot.
1458     then go back and install grub the way everyone else did the first
1459 drobbins 1.21 time. You are done -- congratulations!</impo>
1460 zhen 1.16 <p>If you have any questions or would like to get involved with Gentoo Linux development,
1461 zhen 1.6 consider joining our gentoo-user and gentoo-dev mailing lists
1462 jhhudso 1.75 (there is a &quot;click to subscribe&quot; link on our <uri link="http://www.gentoo.org">main page</uri>).
1463 zhen 1.6 We also have a handy <uri link="http://www.gentoo.org/doc/en/desktop.xml">Desktop configuration guide</uri>
1464     that will
1465     help you to continue configuring your new Gentoo Linux system, and a useful
1466     <uri link="http://www.gentoo.org/doc/en/portage-user.xml">Portage user guide</uri>
1467     to help familiarize you with Portage basics. You can find the rest of the Gentoo Documentation

1477     <title>Gentoo-Stats</title>
1478     <section>
1479     <body>
1480     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
1481 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
1482     us in set priorities our development. Installing it is completely optional, and it would be greatly
1483     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
1484     </p>
1485 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
1486 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
1487     to individually identify your system, nor will it be mached against an IP address or
1488     other personal information. Every precaution has been taken to assure your privacy in the
1489     development of this system. The following are the things that we are monitoring
1490 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
1491 zhen 1.6 </p>
1492 zhen 1.16 <ul>
1493     <li>installed packages and their version numbers</li>
1494     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
1495     <li>memory information (total available physical RAM, total available swap space)</li>
1496     <li>PCI cards and network controller chips</li>
1497     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
1498     </ul>
1499     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
1500 zhen 1.6 (just as it is to the developers).
1501     </p>
1502 zhen 1.16 <ul>
1503     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
1504 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
1505 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
1506     <li>The IP address your data transmission originates from will never be logged
1507     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
1508     </ul>
1509     <p>The installation is easy - just run the following commands:
1510 zhen 1.6 </p>
1511 jhhudso 1.81 <pre caption="Installing gentoo-stats">
1512 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
1513     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
1514 jhhudso 1.81 </pre>
1515 zhen 1.16 <p>The second command above will request a new system ID and enter it into
1516 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
1517     to see additional configuration options.
1518     </p>
1519 zhen 1.16 <p>After that, the program should be run on a regular schedule
1520 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
1521     </p>
1522 jhhudso 1.81 <pre caption="Updating gentoo-stats with cron">
1523     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
1524     </pre>
1525 zhen 1.16 <p>The <c>gentoo-stats</c> program is a simple perl script which can be
1526 jhhudso 1.75 viewed with your favorite pager or editor: <path>/usr/sbin/gentoo-stats</path>. </p>
