74     These instructions step you through the process of installing Gentoo
75     Linux 1.4, release version (not _rc versions). The Gentoo Linux installation
76     process supports various installation approaches, depending upon how much of
77     the system you want to custom-build from scratch.

91     <p>
92 swift 1.176 Welcome to Gentoo Linux! Gentoo Linux can be installed in many different ways.
93     Those who are looking for a rapid install can use pre-built packages, while
94     those who want the ultimate in customizability can compile Gentoo Linux
95     entirely from the original source code. The method you choose is up to you.
96 swift 1.149 </p>
97    
98     <p>
99     One significant change in relation to the official 1.4 release is
100     our new 2-CD installation set, which can be ordered from <uri
101     link="http://store.gentoo.org">The Gentoo Linux Store</uri>, in
102 swift 1.177 addition to being available on our <uri
103     link="http://www.gentoo.org/main/en/mirrors.xml">mirrors</uri>.
104 bennyc 1.165 We currently have 2-CD installation sets for x86 (486 and above),
105     i686 (Pentium Pro, Pentium II, Athlon/Duron and above), Pentium III,
106     Pentium 4 and Athlon XP. To see what 2-CD set is right for you, read
107     the detailed descriptions of each product in the <uri
108 swift 1.149 link="http://store.gentoo.org">store</uri>. The store descriptions
109     contain fairly comprehensive CPU compatibility information.
110     </p>
111    
112 swift 1.167 <p>
113     You can find and download the ISOs for the LiveCDs from most of our
114 swift 1.176 <uri link="http://www.gentoo.org/main/en/mirrors.xml">mirrors</uri>. The
115     LiveCDs for the x86 architecture are located inside the
116 swift 1.167 <path>releases/x86/1.4/livecd/</path> subdirectory.

122     <title>The Installation CDs</title>
123     <body>
124    
125 swift 1.177 <p>
126     So, about the 2 CD set -- here's what's on each CD. The first
127 swift 1.149 CD ("CD 1") is called "Live CD Installation" and is a bootable CD-ROM,
128     meaning that you can put "CD 1" in your drive and run Gentoo Linux
129     directly from the CD. You can then use this CD-based version of
130     Gentoo to install Gentoo Linux 1.4 to your hard disk. In addition
131     to containing a bootable Gentoo Linux environment, CD 1
132     contains everything you need to install Gentoo Linux quickly, even
133     without a connection to the Internet. In addition, several
134     pre-compiled packages are also included on CD 1, such as the
135     ever-important XFree86 X server. If you have an ISO CD-ROM image
136 swift 1.167 file for CD 1, its name will contain <path>-cd1</path>.
137 swift 1.149 </p>
138    
139     <p>
140     In contrast, the second CD ("CD 2") isn't bootable and contains
141     lots of pre-built packages for your system. Included on this CD are
142     optimized versions of packages such as KDE, GNOME, OpenOffice,
143     Mozilla, Evolution and others. CD 2 is <e>optional</e> and is
144     intended for those people who are interested in installing Gentoo
145     Linux very quickly. The packages included on CD 2 typically take
146     about 36 hours to compile from source on a typical modern
147     single-processor system. If you have an ISO CD-ROM image file for CD
148 swift 1.167 2, its name will contain <path>-cd2</path>.
149 swift 1.149 </p>
150    
151     <note>
152     A complete Gentoo Linux 2-CD set contains the Gentoo Reference
153     Platform, which is a complete pre-built Gentoo Linux system including GNOME,
154     KDE, Mozilla and OpenOffice. The Gentoo Reference Platform ("GRP")
155     was created to allow rapid Gentoo Linux package installations
156     for those who need this capability. The "compile from
157     source" functionality, which is the cornerstone of Gentoo Linux,
158     will always be a fully-supported installation option as well. The
159     purpose of the GRP is to make Gentoo Linux more convenient for some
160     users, without impacting Gentoo's powerful "compile from source"
161     installation process in any way.
162     </note>
163    
164     <p>
165     In addition to our 2-CD set, we also have a very small "basic"
166     Live CD that you can use to boot your system. Once your system has
167     booted, you can configure a connection to the Internet and then
168     install Gentoo over the network. The advantage of this "basic" CD is
169     that it is small and thus the ISO CD-ROM image file can be
170     downloaded quickly. If you're an advanced user who wants to install
171     the most up-to-date version of Gentoo Linux available and have a
172     fast network connection, then you may prefer this option. If you
173     have an ISO CD-ROM image file for our "basic" Live CD, its name will
174 swift 1.167 contain <path>-basic</path>.

181     <body>
182    
183 swift 1.149 <p>
184     To use any Gentoo Linux CD-based installation method, you will
185     need to have a 486+ processor and ideally at least 64 Megabytes of
186     RAM. (Gentoo Linux has been successfully built with 64MB of RAM +
187     64MB of swap space, but the build process is awfully slow under
188     those conditions.)

194     <title>Choosing an Installation Method</title>
195     <body>
196    
197 swift 1.149 <p>
198     Once you boot one of our Live CDs, you have even more options.
199     Gentoo Linux can be installed using one of three &quot;stage&quot;
200     tarball files. The one you choose depends on how much of the system
201 swift 1.176 you want to compile yourself. The <e>stage1</e> tarball is used when you
202 swift 1.149 want to bootstrap and build the entire system from scratch. The
203 swift 1.176 <e>stage2</e> tarball is used for building the entire system from a
204     bootstrapped "semi-compiled" state. The <e>stage3</e> tarball already
205 swift 1.149 contains a basic Gentoo Linux system that has been built for
206     you. If you are interested in doing a "GRP" install, then the
207 swift 1.176 stage3 tarball must be used.
208 swift 1.149 </p>
209    
210     <p>
211     <b>If you're not doing a GRP install, should you start from a stage1, stage2, or
212 swift 1.176 stage3 tarball?</b>
213     </p>
214    
215     <p>
216     Here is some information that should help you
217 swift 1.149 make this decision.
218     </p>
219    
220     <p>
221     Starting from a stage1 allows you to have total
222     control over the optimization settings and optional build-time
223     functionality that is initially enabled on your system. This makes
224     stage1 installs good for power users who know what they are doing.
225     It is also a great installation method for those who would like to
226     know more about the inner workings of Gentoo Linux.
227     </p>
228 swift 1.142
229 swift 1.149 <p>
230     Stage2 installs allow you to skip the bootstrap process and doing
231     this is fine if you are happy with the optimization settings that we
232     chose for your particular stage2 tarball.
233     </p>
234 swift 1.142
235 swift 1.149 <p>
236     And choosing to go with a stage3 allows for the fastest install of Gentoo
237     Linux, but also means that your base system will have the optimization
238     settings that we chose for you (which to be honest, are good settings and were
239     carefully chosen to enhance performance while maintaining
240     stability). Since major releases of Gentoo Linux have stage3's
241     specifically optimized for various popular processors, starting
242     from a stage3 can offer the best of all worlds -- a fast install
243     and a system that is well-optimized.
244     </p>
245 swift 1.142
246 swift 1.149 <p>
247     <b>If you're installing Gentoo Linux for the first time, consider using a
248     stage3 tarball for installation, or a stage3 with GRP.</b>
249     </p>
250 antifa 1.106
251 swift 1.149 <note>
252     <b>Advanced users:</b> If you use a stage3 install, you should not
253     change the default CHOST setting in <path>/etc/make.conf</path>. If you need
254     to make such a change, you should start with a stage1 tarball and build up
255     your system with the desired CHOST setting. The CHOST setting
256     typically looks something like this: <c>i686-pc-linux-gnu</c>.
257     </note>
258 antifa 1.106
259 swift 1.149 <impo>
260     If you encounter a problem with any part of the install and wish to
261     report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
262     needs to be sent upstream to the original software developers (e.g. the KDE
263     team) the <e>Gentoo Linux developers</e> will take care of that for you.

277     <title>The Installation Process</title>
278     <body>
279    
280 swift 1.149 <p>
281     Now, let us quickly review the install process. First, we will download, burn
282     CD(s) and boot a LiveCD. After getting a root prompt, we will create
283     partitions, create our filesystems and extract either a stage1, stage2 or
284     stage3 tarball. If we are using a stage1 or stage2 tarball, we will take
285     the appropriate steps to get our system to stage3. Once our system is at
286     stage3, we can configure it (customize configuration files, install a boot
287     loader, etc.), boot it and have a fully-functional Gentoo Linux system. After
288     your basic Gentoo Linux system is running, you can optionally use "CD 2" of
289     our 2-CD set and install any number of pre-built packages such as KDE, GNOME,
290     OpenOffice, Mozilla, or others that you'd like on your system.

367     boot screen with the Gentoo Linux logo on it. At this screen, you
368     can hit Enter to begin the boot process, or boot the LiveCD with

370     and then hitting Enter. For example: <c>gentoo nousb nohotplug</c>.
371     If you are installing Gentoo Linux on a system with more than one
372     processor ("SMP"), then you should type <c>smp</c> instead of

521     When the Live CD boots, it tries to detect all your hardware
522     devices and loads the appropiate kernel modules to support your
523     hardware. In the vast majority of cases, it does a very good job.
524     However, in some cases, it may not auto-load the kernel modules
525     you need. If the PCI auto-detection missed some of your system's hardware, you
526     will have to load the appropriate kernel modules manually.
527     To view a list of all available network card modules, type <c>ls
528     /lib/modules/`uname -r`/kernel/drivers/net/*</c>. To load a particular module,

852     <title>Introduction to block devices</title>
853     <body>
854    
855     <p>
856     In this section, we'll take a good look at disk-oriented aspects of Gentoo
857     Linux and Linux in general, including Linux filesystems, partitions and block
858     devices. Then, once you're familiar with the ins and outs of disks and
859     filesystems, you'll be guided through the process of setting up partitions
860     and filesystems for your Gentoo Linux installation.
861 drobbins 1.86 </p>
862 swift 1.149
863 drobbins 1.86 <p>
864     To begin, I'll introduce "block devices". The most famous block device is
865     probably the one that represents the first IDE drive in a Linux system:
866     </p>
867 swift 1.149
868 drobbins 1.86 <pre caption="/dev/hda, the block device representing the primary master IDE drive in your system">
869     /dev/hda
870     </pre>
871    
872     <p>
873     If your system uses SCSI drives, then your first hard drive will be:
874     </p>
875    
876     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
877     /dev/sda
878     </pre>
879    
880 swift 1.149 <p>
881     The block devices above represent an <e>abstract</e> interface to the disk.
882 drobbins 1.86 User programs can use these block devices to interact with your disk without
883 swift 1.149 worrying about whether your drives are IDE, SCSI or something else. The
884 drobbins 1.86 program can simply address the storage on the disk as a bunch of contiguous,
885 swift 1.149 randomly-accessible 512-byte blocks.

891     <title>Partitions and fdisk</title>
892     <body>
893    
894 swift 1.149 <p>
895     Under Linux, we create filesystems by using a special command called
896     <c>mkfs</c> (or <c>mke2fs</c>, <c>mkreiserfs</c>, etc.), specifying a particular
897     block device as a command-line argument.
898     </p>
899    
900     <p>
901     However, although it is theoretically possible to use a "whole disk" block
902     device (one that represents the <e>entire</e> disk) like <path>/dev/hda</path>
903     or <path>/dev/sda</path> to house a single filesystem, this is almost never
904     done in practice. Instead, full disk block devices are split up into smaller,
905     more manageable block devices called "partitions". Partitions are created
906     using a tool called <c>fdisk</c>, which is used to create and edit the
907     partition table that's stored on each disk. The partition table defines
908     exactly how to split up the full disk.
909     </p>
910    
911     <p>
912     We can take a look at a disk's partition table by running <c>fdisk</c>,
913     specifying a block device that represents a full disk as an argument:

974     This particular disk is configured to house seven Linux filesystems (each
975 drobbins 1.86 with a corresponding partition listed as "Linux") as well as a swap partition
976 swift 1.149 (listed as "Linux swap").
977     </p>
978 drobbins 1.86
979     <p>
980     Notice the name of the corresponding partition block
981 swift 1.149 devices on the left hand side, starting with <path>/dev/hda1</path> and going
982     up to <path>/dev/hda9</path>. In the early days of the PC, partitioning
983     software only allowed a maximum of four partitions (called "primary"
984     partitions). This was too limiting, so a workaround called <e>extended
985     partitioning</e> was created. An extended partition is very similar to a
986     primary partition and counts towards the primary partition limit of four.
987     However, extended partitions can hold any number of so-called <e>logical</e>
988     partitions inside them, providing an effective means of working around the
989     four partition limit.
990     </p>
991    
992     <p>
993     All partitions <path>/dev/hda5</path> and higher are logical partitions.
994     The numbers 1 through 4 are reserved for primary or extended partitions.
995 drobbins 1.86 </p>
996    
997     <p>
998 swift 1.149 So, In our example, <path>/dev/hda1</path> through <path>/dev/hda3</path> are
999     primary partitions. <path>/dev/hda4</path> is an extended partition that
1000     contains logical partitions <path>/dev/hda5</path> through
1001     <path>/dev/hda9</path>. You would never actually <e>use</e>
1002     <path>/dev/hda4</path> for storing any filesystems directly -- it simply
1003     acts as a container for partitions <path>/dev/hda5</path> through
1004     <path>/dev/hda9</path>.
1005     </p>
1006 drobbins 1.86
1007 swift 1.149 <p>
1008     Also, notice that each partition has an "Id", also called a "partition
1009 drobbins 1.86 type". Whenever you create a new partition, you should ensure that the
1010     partition type is set correctly. '83' is the correct partition type for
1011 swift 1.115 partitions that will be housing Linux filesystems, '82' is the correct
1012     partition type for Linux swap partitions and 'fd' is the recommended partition
1013     type for Software RAID partitions. You set the partition type using the
1014 drobbins 1.86 <c>t</c> option in <c>fdisk</c>. The Linux kernel uses the partition type
1015 peesh 1.99 setting to auto-detect filesystems and swap devices on the disk at boot-time.

1045 swift 1.149 <p>
1046     In our suggested "newbie" partition configuration, we have three partitions.
1047     The first one (<path>/dev/hda1</path>) at the beginning of the disk is a small
1048 drobbins 1.86 partition called a boot partition. The boot partition's purpose is to hold all
1049     the critical data related to booting -- GRUB boot loader information (if you
1050     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
1051     us a safe place to store everything related to booting Linux. During normal
1052     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
1053 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
1054 swift 1.149 likely end up being <path>/dev/sda1</path>.
1055     </p>
1056 drobbins 1.86
1057 swift 1.149 <p>
1058     It's recommended to have boot partitions (containing everything necessary for
1059 drobbins 1.98 the boot loader to work) at the beginning of the disk. While not necessarily
1060     required anymore, it is a useful tradition from the days when the lilo boot
1061     loader wasn't able to load kernels from filesystems that extended beyond disk
1062     cylinder 1024.
1063     </p>
1064    
1065 swift 1.149 <p>
1066     The second partition (<path>/dev/hda2</path>) is used to for swap space. The
1067 drobbins 1.86 kernel uses swap space as virtual memory when RAM becomes low. This partition,
1068     relatively speaking, isn't very big either, typically somewhere around 512MB.
1069 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
1070 swift 1.149 being called <path>/dev/sda2</path>.
1071     </p>
1072 drobbins 1.86
1073 swift 1.149 <p>
1074     The third partition (<path>/dev/hda3</path>) is quite large and takes up the
1075     rest of the disk. This partition is called our "root" partition and will be
1076     used to store your main filesystem that houses Gentoo Linux itself. On a SCSI
1077     system, this partition would likely end up being <path>/dev/sda3</path>.

1299     Gentoo Linux supports a variety of different types of filesystems; each type has
1300     its strengths and weaknesses and its own set of performance characteristics.
1301     Currently, we support the creation of ext2, ext3, XFS, JFS and ReiserFS
1302     filesystems.
1303     </p>
1304 drobbins 1.86
1305 swift 1.149 <p>
1306     ext2 is the tried and true Linux filesystem but doesn't have metadata
1307 drobbins 1.86 journaling, which means that routine ext2 filesystem checks at startup time can
1308     be quite time-consuming. There is now quite a selection of newer-generation
1309 swift 1.149 <e>journaled</e> filesystems that can be checked for consistency very quickly
1310 drobbins 1.86 and are thus generally preferred over their non-journaled counterparts.
1311     Journaled filesystems prevent long delays when you boot your system and your
1312 swift 1.149 filesystem happens to be in an <e>inconsistent</e> state.
1313     </p>
1314 drobbins 1.86
1315 swift 1.149 <p>
1316     ext3 is the journaled version of the ext2 filesystem, providing metadata
1317 drobbins 1.86 journaling for fast recovery in addition to other enhanced journaling modes
1318     like full data and ordered data journaling. ext3 is a very good and reliable
1319 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
1320     Because it does not extensively employ the use of "trees" in its internal
1321     design, it doesn't scale very well, meaning that it is not an ideal choice for
1322     very large filesystems, or situations where you will be handling very large
1323     files or large quantities of files in a single directory. But when used within
1324 swift 1.149 its design parameters, ext3 is an excellent filesystem.
1325     </p>
1326 drobbins 1.86
1327 swift 1.149 <p>
1328     ReiserFS is a B*-tree based filesystem that has very good overall
1329 drobbins 1.86 performance and greatly outperforms both ext2 and ext3 when dealing with small
1330     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
1331     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
1332     now rock-solid and highly recommended for use both as a general-purpose
1333     filesystem and for extreme cases such as the creation of large filesystems, the
1334 swift 1.149 use of many small files, very large files and directories containing tens of
1335 drobbins 1.86 thousands of files. ReiserFS is the filesystem we recommend by default for all
1336 swift 1.149 non-boot partitions.
1337     </p>
1338 drobbins 1.86
1339 swift 1.149 <p>
1340     XFS is a filesystem with metadata journaling that is fully supported under
1341     Gentoo Linux's <c>xfs-sources</c> kernel. It comes with a robust
1342 drobbins 1.86 feature-set and is optimized for scalability. We only recommend using this
1343     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
1344     a uninterruptible power supply. Because XFS aggressively caches in-transit data
1345     in RAM, improperly designed programs (those that don't take proper precautions
1346 swift 1.149 when writing files to disk and there are quite a few of them) can lose a good
1347     deal of data if the system goes down unexpectedly.

1351     JFS is IBM's high-performance journaling filesystem. It has recently
1352     become production-ready and there hasn't been a sufficient track record to
1353 swift 1.142 comment positively nor negatively on its general stability at this
1354 swift 1.149 point.
1355     </p>
1356 drobbins 1.86
1357 swift 1.149 <p>
1358     If you're looking for the most rugged journaling filesystem, use ext3. If
1359 drobbins 1.86 you're looking for a good general-purpose high-performance filesystem with
1360     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
1361 swift 1.149 refined and recommended for general use.

1374    
1375 swift 1.149 <p>
1376     We choose ext3 for our <path>/dev/hda1</path> boot partition because it is a
1377 drobbins 1.98 robust journaling filesystem supported by all major boot loaders. We used
1378 swift 1.149 <c>mkswap</c> for our <path>/dev/hda2</path> swap partition -- the choice is
1379     obvious here. And for our main root filesystem on <path>/dev/hda3</path> we
1380     choose ReiserFS, since it is a solid journaling filesystem offering excellent
1381     performance. Now, go ahead and initialize your partitions.

1436     You may want to add a couple of additional flags to the <c>mkfs.xfs</c>
1437     command: <c>-d agcount=3 -l size=32m</c>. The <c>-d agcount=3</c> command
1438     will lower the number of allocation groups. XFS will insist on using at
1439     least 1 allocation group per 4 GB of your partition, so, for example, if
1440     you have a 20 GB partition you will need a minimum agcount of 5. The
1441     <c>-l size=32m</c> command increases the journal size to 32 Mb, increasing

1475     <path>/mnt/gentoo</path> will be placed on our new filesystems.
1476     Note that if you are setting up Gentoo Linux with separate
1477     <path>/usr</path> or <path>/var</path> filesystems, these would get mounted to
1478     <path>/mnt/gentoo/usr</path> and <path>/mnt/gentoo/var</path> respectively.

1480    
1481     <impo>
1482     If your <path>/boot</path> partition (the one holding the kernel) is ReiserFS,

1700     Now, you will need to run <c>emerge sync</c>. This command tells Portage
1701 swift 1.142 to download the most recent copy of the Gentoo Linux Portage tree from the
1702 swift 1.149 Internet. If you extracted a Portage tree snapshot from <e>CD 1</e> earlier,
1703     you can safely skip this step. The Portage tree contains all the scripts
1704 swift 1.142 (called ebuilds) used to build every package under Gentoo Linux. Currently,
1705     we have ebuild scripts for close to 4000 packages. Once <c>emerge sync</c>
1706     completes, you will have a complete Portage tree in
1707 swift 1.149 <path>/usr/portage</path>:

1723     <p>
1724     Now that you have a working copy of the Portage tree, it is time to
1725 drobbins 1.86 customize the optimization and optional build-time settings to use on your
1726     Gentoo Linux system. Portage will use these settings when compiling any
1727     programs for you. To do this, edit the file <path>/etc/make.conf</path>. In
1728 swift 1.149 this file, you should set your USE flags, which specify optional
1729 drobbins 1.86 functionality that you would like to be built into packages if available;
1730 swift 1.182 generally, the defaults (an <e>empty</e> or unset USE variable) are fine.
1731     More information on USE flags can be found in the <uri
1732     link="http://www.gentoo.org/doc/en/use-howto.xml">Gentoo Guide to USE
1733     flags</uri>. A complete list of current USE flags can be found in the <uri

1739     If you are starting from a stage1 tarball, You also should set appropriate
1740     CHOST, CFLAGS and CXXFLAGS settings for the kind of system that you are
1741     creating (commented examples can be found further down in the file). If you
1742     are using a stage2 or stage3 tarball, these settings will already be configured
1743     optimally and should not require any modification.

2042     There are two options for installing a kernel. You can either configure your
2043     own kernel or use the <c>genkernel</c> utility to configure and compile your
2044     kernel automatically.
2045     </p>
2046 swift 1.177
2047 swift 1.149 <p>
2048 swift 1.182 Whether configuring a kernel by hand or using <c>genkernel</c>, you'll need
2049     to merge the Linux kernel sources you'd like to use. Gentoo provides
2050     several kernel ebuilds; a list can be found in the <uri
2051     link="/doc/en/gentoo-kernel.xml">Gentoo Linux Kernel Guide</uri>. If you are
2052     uncertain which kernel sources to choose, we advise using
2053     <c>gentoo-sources</c>. If you want XFS support, you should choose
2054     <c>xfs-sources</c> or <c>gs-sources</c>. Gentoo's LiveCD uses
2055     <c>gs-sources</c> and <c>xfs-sources</c>. There is also a
2056     <c>gaming-sources</c> kernel optimized for game-playing responsiveness that
2057     works wonderfully for this purpose when the "Preemptible kernel" option is
2058     enabled.

2070     The <path>/usr/src/linux</path> symbolic link will point to your
2071     newly-installed kernel source tree. Portage uses the
2072     <path>/usr/src/linux</path> symbolic link for a special purpose. Any ebuilds
2073     you install that contain kernel modules will be configured to work with the
2074     kernel source tree pointed to by <path>/usr/src/linux</path>.
2075     <path>/usr/src/linux</path> is created when you emerge your first kernel
2076     source package, but after it exists, Portage does not modify this symbolic

2086     <p>
2087     Now that your kernel source tree is installed, it's now time to compile your
2088     kernel. There are two ways to do this. The first way is to use our new
2089     <c>genkernel</c> script to automatically build a kernel for you.
2090     <c>genkernel</c> works by configuring a kernel nearly identically to the way
2091     our LiveCD kernel is configured. This means that when you use <c>genkernel</c>
2092     to build your kernel, your system will generally detect all your hardware at
2093     boot-time, just like our Live CD does. Because genkernel doesn't require any
2094     manual kernel configuration, it is an ideal solution for those users who may
2095     not be comfortable compiling their own kernels.
2096     </p>
2097    
2098     <p>
2099     Now, let's see how to use genkernel. First, emerge the genkernel ebuild:

2150     Once <c>genkernel</c> completes, a kernel, full set of modules and
2151     <e>initial root disk</e> (initrd) will be created. We will use the kernel
2152 swift 1.161 and initrd when configuring a boot loader later in this document. Write
2153     down the names of the kernel and initrd as you will need it when writing
2154     the bootloader configuration file. The initrd will be started immediately after
2155     booting to perform hardware autodetection (just like on the Live CD) before
2156     your "real" system starts up.
2157 swift 1.149 </p>
2158    
2159     <p>
2160     Now, let's perform one more step to get our system to be more like the Live
2161     CD -- let's emerge <c>hotplug</c>. While the initrd autodetects hardware that
2162     is needed to boot your system, <c>hotplug</c> autodetects everything else.
2163     To emerge and enable <c>hotplug</c>, type the following:
2164     </p>
2165 swift 1.142
2166     <pre caption="Emerging and enabling hotplug">

2170    
2171 swift 1.149 <p>
2172     Now that you've run and configured your system to use <c>genkernel</c>, you
2173     can skip the "manual kernel configuration" section below.

2183     If you opted not to use genkernel to compile your kernel, this section
2184 swift 1.142 will guide you through the process of configuring and compiling a kernel by
2185     hand. Please note that <path>/usr/src/linux</path> is a symlink to your
2186 swift 1.149 current emerged kernel source package and is set automatically by Portage at
2187 swift 1.142 emerge time. If you have multiple kernel source packages, it is necessary to
2188     set the <path>/usr/src/linux</path> symlink to the correct one before
2189 swift 1.149 proceeding.
2190     </p>
2191 swift 1.142
2192     <warn>
2193 swift 1.149 If you are configuring your own kernel, be careful with the <i>grsecurity</i>
2194     option. Being too aggressive with your security settings can cause certain
2195     programs (such as X) to not run properly. If in doubt, leave it out.
2196 swift 1.142 </warn>
2197    
2198     <note>
2199 swift 1.149 If you want to use the same configuration as the LiveCD kernel or base
2200     your configuration on it, you should execute <c>cd /usr/src/linux &amp;&amp; cat /proc/config > .config &amp;&amp; make oldconfig</c>.
2201     If you aren't using <c>xfs-sources</c>, this will ask some questions
2202     about differences between your kernelchoice and <c>xfs-sources</c>.

2258     If you use PPPoE to connect to Internet, you will need the following
2259     options in the kernel (built-in or as preferably as modules) : &quot;PPP
2260     (point-to-point protocol) support&quot;, &quot;PPP support for async serial
2261     ports&quot;, &quot;PPP support for sync tty ports&quot;. The two compression
2262     options won't harm but are not definitely needed, neither does the &quot;PPP

2270     and ATAPI Block devices&quot; ---&gt; &quot;SCSI emulation support&quot;
2271     (I usually make it a module), then under &quot;SCSI support&quot; enable
2272     &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and &quot;SCSI
2273     generic support&quot; (again, I usually compile them as modules). If you

2284     <note>
2285     For those who prefer it, it is possible to install Gentoo Linux with a 2.2
2286     kernel. However, doing this comes at a price: you will lose many of the nifty
2287     features that are new to the 2.4 series kernels (such as XFS and tmpfs
2288     filesystems, iptables and more), although the 2.2 kernel sources can be
2289     patched with ReiserFS and devfs support.
2290     Gentoo linux boot scripts require either tmpfs or ramdisk support in the
2291     kernel, so 2.2 kernel users need to make sure that ramdisk support is compiled
2292     in (ie, not a module). It is <comment>vital</comment> that a
2293     <e>gentoo=notmpfs</e> flag be added to the kernel line in
2294     <path>/boot/grub/grub.conf</path> or to the append line in
2295     <path>/etc/lilo.conf</path> for the 2.2 kernel so that a ramdisk is mounted
2296     for the boot scripts instead of tmpfs. If you choose not to use devfs, then
2297     <e>gentoo=notmpfs,nodevfs</e> should be used instead.

2394 swift 1.173 syslog-ng as well as metalog. If in doubt, you may want to try
2395     syslog-ng, since it is very flexible and feature-rich. To merge your logger of

2750     In the spirit of Gentoo, users now have more than one bootloader to choose
2751     from. Using our virtual package system, users are now able to choose between
2752     both GRUB and LILO as their bootloaders.
2753     </p>
2754    
2755     <p>
2756     Please keep in mind that having both bootloaders installed is not necessary.
2757     In fact, it can be a hindrance, so please only choose one.
2758     </p>
2759    
2760     <p>
2761     In addition, you will need to configure our bootloader differently depending
2762     upon whether you are using <c>genkernel</c> (with kernel and initrd) or a
2763     kernel you compiled by hand. Be sure to take note of the important
2764     differences.

2770     <title>Configuring GRUB</title>
2771     <body>
2772    
2773     <p>
2774     The most critical part of understanding GRUB is getting comfortable with how
2775     GRUB refers to hard drives and partitions. Your Linux partition
2776     <path>/dev/hda1</path> is called <path>(hd0,0)</path> under GRUB. Notice the
2777     parenthesis around the hd0,0 - they are required. Hard drives count from zero
2778     rather than "a" and partitions start at zero rather than one. Be aware too
2779     that with the hd devices, only hard drives are counted, not atapi-ide devices
2780     such as cdrom players, burners and that the same construct can be used with
2781     scsi drives. (Normally they get higher numbers than ide drives except when the
2782     bios is configured to boot from scsi devices.) Assuming you have a hard drive
2783     on <path>/dev/hda</path>, a cdrom player on <path>/dev/hdb</path>, a burner on
2784     <path>/dev/hdc</path>, a second hard drive on <path>/dev/hdd</path> and no
2785     SCSI hard drive, <path>/dev/hdd7</path> gets translated to
2786     <path>(hd1,6)</path>. It might sound tricky and tricky it is indeed, but as
2787     we will see, GRUB offers a tab completion mechanism that comes handy for
2788     those of you having a lot of hard drives and partitions and who are a little
2789     lost in the GRUB numbering scheme. Having gotten the feel for that, it is
2790     time to install GRUB.
2791     </p>
2792    
2793     <p>
2794     The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted
2795     shell prompt:
2796     </p>
2797    
2798 jhhudso 1.81 <pre caption="Installing GRUB">
2799 swift 1.149 # <i>emerge -k grub</i>
2800     # <i>grub</i>
2801 jhhudso 1.81 </pre>
2802 swift 1.149
2803     <p>
2804     You will be presented with the <e>grub&gt;</e> grub command-line prompt.
2805     Now, you need to type in the right commands to install the GRUB boot record
2806     onto your hard drive. In my example configuration, I want to install the GRUB
2807     boot record on my hard drive's MBR (master boot record), so that the first
2808     thing I see when I turn on the computer is the GRUB prompt. In my case, the
2809     commands I want to type are:
2810     </p>
2811 zhen 1.68
2812 jhhudso 1.81 <pre caption="GRUB on the MBR">
2813 swift 1.149 grub&gt; <i>root (hd0,0)</i> <comment>(Your boot partition)</comment>
2814     grub&gt; <i>setup (hd0)</i> <comment>(Where the boot record is installed; here, it is the MBR)</comment>
2815 jhhudso 1.81 </pre>
2816 swift 1.177
2817 jhhudso 1.81 <pre caption="GRUB not on the MBR">
2818 swift 1.149 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR:</comment>
2819     grub&gt; <i>root (hd0,0)</i> <comment>(Your boot partition)</comment>
2820     grub&gt; <i>setup (hd0,4)</i> <comment>(Where the boot record is installed; here it is /dev/hda5)</comment>
2821     grub&gt; <i>quit</i>
2822     </pre>
2823    
2824     <p>
2825     Here is how the two commands work. The first <c>root ( )</c> command tells
2826     GRUB the location of your boot partition (in our example,
2827     <path>/dev/hda1</path> or <path>(hd0,0)</path> in GRUB terminology. Then, the
2828     second <c>setup ( )</c> command tells GRUB where to install the boot record -
2829     it will be configured to look for its special files at the <c>root ( )</c>
2830     location that you specified. In my case, I want the boot record on the MBR
2831     of the hard drive, so I simply specify <path>/dev/hda</path> (also known as
2832     <path>(hd0)</path>). If I were using another boot loader and wanted to set up
2833     GRUB as a secondary boot-loader, I could install GRUB to the boot record of
2834     a particular partition. In that case, I would specify a particular partition
2835     rather than the entire disk. Once the GRUB boot record has been successfully
2836     installed, you can type <c>quit</c> to quit GRUB.
2837     </p>
2838    
2839     <note>
2840     The tab completion mechanism of GRUB can be used from within GRUB,
2841     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
2842     be prompted with a list of the available devices (not only hard drives),
2843     hitting the TAB key having written <c> root (hd</c>, GRUB would print the
2844     available hard drives and hitting the TAB key after writing <c> root (hd0,</c>
2845     would make GRUB print the list of partitions on the first hard drive.
2846     Checking the syntax of the GRUB location with completion should really help
2847     to make the right choice.

2851     Gentoo Linux is now installed, but we need to create the

2854     </p>
2855    
2856     <impo>
2857     To ensure backwards compatibility with GRUB, make sure to make a link from

2898     If you set up SCSI emulation for an IDE cd burner earlier, then to get it to

2905     After saving this file, Gentoo Linux installation is complete. Selecting the
2906     first option will tell GRUB to boot Gentoo Linux without a fuss. The second
2907     part of the <path>grub.conf</path> file is optional and shows you how to use
2908     GRUB to boot a bootable Windows partition.
2909     </p>
2910    
2911     <note>
2912     Above, <path>(hd0,0)</path> should point to your "boot" partition
2913     (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path>
2914     should point to your root filesystem. <path>(hd0,5)</path> contains the NT
2915     boot loader.
2916     </note>
2917    
2918     <note>
2919     The path to the kernel image is relative to the boot partition. If for
2920     example you have separated boot partition <path>(hd0,0)</path> and root
2921     partition <path>(hd0,1)</path>, all paths in the <path>grub.conf</path> file
2922     above will become <path>/bzImage</path>.
2923     </note>
2924    
2925     <p>
2926     If you need to pass any additional options to the kernel, simply add them to
2927     the end of the <c>kernel</c> command. We're already passing one option
2928     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you
2929     can turn off devfs by default (not recommended unless you know what you're
2930     doing) by adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c>
2931     command.
2932     </p>
2933    
2934     <note>
2935     Unlike in earlier versions of Gentoo Linux, you no longer have to add
2936     <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs.
2937     Now devfs is enabled by default.

3001 swift 1.177 <li>
3002     <c>boot=/dev/hda</c> tells LILO to install itself on the first hard disk on
3003     the first IDE controller
3004     </li>
3005     <li>
3006     <c>map=/boot/map</c> states the map file. In normal use, this should not be
3007     modified
3008     </li>
3009     <li>
3010     <c>install=/boot/boot.b</c> tells LILO to install the specified file as the
3011     new boot sector. In normal use, this should not be altered. If the install
3012     line is missing, LILO will assume a default of <path>/boot/boot.b</path> as
3013     the file to be used.
3014     </li>
3015     <li>
3016     The existence of <c>prompt</c> tells LILO to display the classic <e>lilo:</e>
3017     prompt at bootup. While it is not recommended that you remove the prompt line,
3018     if you do remove it, you can still get a prompt by holding down the [Shift]
3019     key while your machine starts to boot.
3020     </li>
3021     <li>
3022     <c>timeout=50</c> sets the amount of time that LILO will wait for user input
3023     before proceeding with booting the default line entry. This is measured in
3024     tenths of a second, with 50 as the default.
3025     </li>
3026     <li>
3027     <c>lba32</c> describes the hard disk geometry to LILO. Another common entry
3028     here is linear. You should not change this line unless you are very aware of
3029     what you are doing. Otherwise, you could put your system in an unbootable
3030     state.
3031     </li>
3032     <li>
3033     <c>default=linux</c> refers to the default operating system for LILO to boot
3034     from the options listed below this line. The name linux refers to the label
3035     line below in each of the boot options.
3036     </li>
3037     <li>
3038     <c>image=/boot/bzImage</c> specifies the linux kernel to boot with this
3039     particular boot option
3040     </li>
3041     <li>
3042     <c>label=linux</c> names the operating system option in the LILO screen. In
3043     this case, it is also the name referred to by the default line.
3044     </li>
3045     <li>
3046     <c>read-only</c> specifies that the root partition (see the root line below)
3047     is read-only and cannot be altered during the boot process.
3048     </li>
3049     <li>
3050     <c>root=/dev/hda3</c> tells LILO what disk partition to use as the root

3140     <p>
3141     It is always a good idea to make a boot disk the first
3142     time you install any Linux distribution. This is a security
3143     blanket and generally not a bad thing to do. If your hardware doesn't
3144     let you install a working bootloader from the chrooted environment,
3145     you may <e>need</e> to make a GRUB boot disk.
3146     If you are in this camp, make a GRUB boot disk and when you reboot
3147     the first time you can install GRUB to the MBR. Make your bootdisks
3148     like this:

3157     Now reboot and load the floppy. At the floppy's <c>grub&gt;</c> prompt, you
3158     can now execute the necessary <c>root</c> and <c>setup</c> commands.

3190     GRP users can, at this point, install binary packages:

3192 swift 1.142
3193     <pre caption="Installing from GRP">
3194 swift 1.167 # <i>emerge -k xfree</i>
3195 swift 1.142 </pre>
3196    
3197 swift 1.149 <p>
3198     CD 1 contains enough applications to install a working system with XFree86.
3199     Additionally, CD2 of the 2-CD GRP set contains other applications including
3200     KDE, GNOME, Mozilla and others. To install these packages, you will need to
3201     reboot into your new Gentoo system first (covered in the "Installation
3202     complete!" section near the end of this document). After you are running your
3203     basic Gentoo system from the hard drive, you can mount the second CD and copy
3204     files:
3205     </p>
3206 swift 1.142
3207 swift 1.149 <pre caption="Loading binary packages from CD2">

3210 swift 1.142 </pre>
3211    
3212 swift 1.149 <p>
3213     Now various other applications can be installed the same way. For example:

3230     Now, Gentoo Linux is installed. The only remaining step is to update necessary
3231     configuration files, exit the chrooted shell, safely unmount your partitions
3232     and reboot the system:

3234 jhhudso 1.75
3235 swift 1.142 <warn>
3236     <c>etc-update</c> can provide you with a list of configuration files
3237     that have newer versions at your disposal. Verify that none of the
3238     configuration files have a big impact (such as <path>/etc/fstab</path>,
3239     <path>/etc/make.conf</path>, <path>/etc/rc.conf</path>, ...). Merge the
3240     files that don't have such a big impact, remove the updates of the
3241     others or view the diff and manually update the configuration file.

3255 swift 1.149
3256     <note>
3257 swift 1.164 After rebooting, it is a good idea to run the <c>modules-update</c> command to
3258 swift 1.149 create the <path>/etc/modules.conf</path> file. Instead of modifying this
3259     file directly, you should generally make changes to the files in
3260     <path>/etc/modules.d</path>.
