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

76     <title>About the Install</title>
77     <section>
78     <body>
79    
80     <p>
81     First, if you are new to this, welcome to Gentoo Linux! Gentoo
82     Linux can be installed in many different ways. Those who are looking
83     for a rapid install can use pre-built packages, while those who want
84     the ultimate in customizability can compile Gentoo Linux entirely
85     from the original source code. The method you choose is up to
86     you.
87     </p>
88    
89     <p>
90     One significant change in relation to the official 1.4 release is
91     our new 2-CD installation set, which can be ordered from <uri
92     link="http://store.gentoo.org">The Gentoo Linux Store</uri>, in
93     addition to being available on our mirrors. We currently have 2-CD
94     installation sets for x86 (486 and above), i686 (Pentium Pro,
95     Pentium II, Athlon/Duron and above), Pentium III, Pentium 4 and Athlon XP.
96     To see what 2-CD set is right for you, read the detailed
97     descriptions of each product in the <uri
98     link="http://store.gentoo.org">store</uri>. The store descriptions
99     contain fairly comprehensive CPU compatibility information.
100     </p>
101    
102     <p>So, about the 2 CD set -- here's what's on each CD. The first
103     CD ("CD 1") is called "Live CD Installation" and is a bootable CD-ROM,
104     meaning that you can put "CD 1" in your drive and run Gentoo Linux
105     directly from the CD. You can then use this CD-based version of
106     Gentoo to install Gentoo Linux 1.4 to your hard disk. In addition
107     to containing a bootable Gentoo Linux environment, CD 1
108     contains everything you need to install Gentoo Linux quickly, even
109     without a connection to the Internet. In addition, several
110     pre-compiled packages are also included on CD 1, such as the
111     ever-important XFree86 X server. If you have an ISO CD-ROM image
112     file for CD 1, its name will end in "<path>-cd1.iso</path>".
113     </p>
114    
115     <p>
116     In contrast, the second CD ("CD 2") isn't bootable and contains
117     lots of pre-built packages for your system. Included on this CD are
118     optimized versions of packages such as KDE, GNOME, OpenOffice,
119     Mozilla, Evolution and others. CD 2 is <e>optional</e> and is
120     intended for those people who are interested in installing Gentoo
121     Linux very quickly. The packages included on CD 2 typically take
122     about 36 hours to compile from source on a typical modern
123     single-processor system. If you have an ISO CD-ROM image file for CD
124     2, its name will end in "<path>-cd2.iso</path>".
125     </p>
126    
127     <note>
128     A complete Gentoo Linux 2-CD set contains the Gentoo Reference
129     Platform, which is a complete pre-built Gentoo Linux system including GNOME,
130     KDE, Mozilla and OpenOffice. The Gentoo Reference Platform ("GRP")
131     was created to allow rapid Gentoo Linux package installations
132     for those who need this capability. The "compile from
133     source" functionality, which is the cornerstone of Gentoo Linux,
134     will always be a fully-supported installation option as well. The
135     purpose of the GRP is to make Gentoo Linux more convenient for some
136     users, without impacting Gentoo's powerful "compile from source"
137     installation process in any way.
138     </note>
139    
140     <p>
141     In addition to our 2-CD set, we also have a very small "basic"
142     Live CD that you can use to boot your system. Once your system has
143     booted, you can configure a connection to the Internet and then
144     install Gentoo over the network. The advantage of this "basic" CD is
145     that it is small and thus the ISO CD-ROM image file can be
146     downloaded quickly. If you're an advanced user who wants to install
147     the most up-to-date version of Gentoo Linux available and have a
148     fast network connection, then you may prefer this option. If you
149     have an ISO CD-ROM image file for our "basic" Live CD, its name will
150     end in "<path>-basic.iso</path>".
151     </p>
152 drobbins 1.70
153 swift 1.149 <p>
154     To use any Gentoo Linux CD-based installation method, you will
155     need to have a 486+ processor and ideally at least 64 Megabytes of
156     RAM. (Gentoo Linux has been successfully built with 64MB of RAM +
157     64MB of swap space, but the build process is awfully slow under
158     those conditions.)
159     </p>
160    
161     <p>
162     Once you boot one of our Live CDs, you have even more options.
163     Gentoo Linux can be installed using one of three &quot;stage&quot;
164     tarball files. The one you choose depends on how much of the system
165     you want to compile yourself. The stage1 tarball is used when you
166     want to bootstrap and build the entire system from scratch. The
167     stage2 tarball is used for building the entire system from a
168     bootstrapped "semi-compiled" state. The stage3 tarball already
169     contains a basic Gentoo Linux system that has been built for
170     you. If you are interested in doing a "GRP" install, then the
171     stage3 tarball should be used.
172     </p>
173    
174     <p>
175     <b>If you're not doing a GRP install, should you start from a stage1, stage2, or
176     stage3 tarball?</b> Here is some information that should help you
177     make this decision.
178     </p>
179    
180     <p>
181     Starting from a stage1 allows you to have total
182     control over the optimization settings and optional build-time
183     functionality that is initially enabled on your system. This makes
184     stage1 installs good for power users who know what they are doing.
185     It is also a great installation method for those who would like to
186     know more about the inner workings of Gentoo Linux.
187     </p>
188 swift 1.142
189 swift 1.149 <p>
190     Stage2 installs allow you to skip the bootstrap process and doing
191     this is fine if you are happy with the optimization settings that we
192     chose for your particular stage2 tarball.
193     </p>
194 swift 1.142
195 swift 1.149 <p>
196     And choosing to go with a stage3 allows for the fastest install of Gentoo
197     Linux, but also means that your base system will have the optimization
198     settings that we chose for you (which to be honest, are good settings and were
199     carefully chosen to enhance performance while maintaining
200     stability). Since major releases of Gentoo Linux have stage3's
201     specifically optimized for various popular processors, starting
202     from a stage3 can offer the best of all worlds -- a fast install
203     and a system that is well-optimized.
204     </p>
205 swift 1.142
206 swift 1.149 <p>
207     <b>If you're installing Gentoo Linux for the first time, consider using a
208     stage3 tarball for installation, or a stage3 with GRP.</b>
209     </p>
210 antifa 1.106
211 swift 1.149 <note>
212     <b>Advanced users:</b> If you use a stage3 install, you should not
213     change the default CHOST setting in <path>/etc/make.conf</path>. If you need
214     to make such a change, you should start with a stage1 tarball and build up
215     your system with the desired CHOST setting. The CHOST setting
216     typically looks something like this: <c>i686-pc-linux-gnu</c>.

220     If you encounter a problem with any part of the install and wish to
221     report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
222     needs to be sent upstream to the original software developers (e.g. the KDE
223     team) the <e>Gentoo Linux developers</e> will take care of that for you.

227     The installation instructions in the LiveCD may not be as up-to-date as our
228     Web documentation at <uri>http://www.gentoo.org/doc/en/gentoo-x86-install.xml</uri>.

234     Now, let us quickly review the install process. First, we will download, burn
235     CD(s) and boot a LiveCD. After getting a root prompt, we will create
236     partitions, create our filesystems and extract either a stage1, stage2 or
237     stage3 tarball. If we are using a stage1 or stage2 tarball, we will take
238     the appropriate steps to get our system to stage3. Once our system is at
239     stage3, we can configure it (customize configuration files, install a boot
240     loader, etc.), boot it and have a fully-functional Gentoo Linux system. After
241     your basic Gentoo Linux system is running, you can optionally use "CD 2" of
242     our 2-CD set and install any number of pre-built packages such as KDE, GNOME,
243     OpenOffice, Mozilla, or others that you'd like on your system.

305     Start by booting your Live CD of choice. You should see a fancy
306     boot screen with the Gentoo Linux logo on it. At this screen, you
307     can hit Enter to begin the boot process, or boot the LiveCD with
308     custom boot options by specifying a kernel followed by boot options
309     and then hitting Enter. For example: <c>gentoo nousb nohotplug</c>.
310     If you are installing Gentoo Linux on a system with more than one
311     processor ("SMP"), then you should type <c>smp</c> instead of
312     <c>gentoo</c> at the prompt. This will allow the LiveCD to see all

395    
396     <p>
397     When the Live CD boots, it tries to detect all your hardware
398     devices and loads the appropiate kernel modules to support your
399     hardware. In the vast majority of cases, it does a very good job.
400     However, in some cases, it may not auto-load the kernel modules
401     you need. If the PCI auto-detection missed some of your system's hardware, you
402     will have to load the appropriate kernel modules manually.
403     To view a list of all available network card modules, type <c>ls
404     /lib/modules/`uname -r`/kernel/drivers/net/*</c>. To load a particular module,
405     type:
406     </p>

411 jhhudso 1.81 </pre>
412 swift 1.149
413     <p>

692     <title>Introduction to block devices</title>
693     <body>
694    
695     <p>
696     In this section, we'll take a good look at disk-oriented aspects of Gentoo
697     Linux and Linux in general, including Linux filesystems, partitions and block
698     devices. Then, once you're familiar with the ins and outs of disks and
699     filesystems, you'll be guided through the process of setting up partitions
700     and filesystems for your Gentoo Linux installation.
701 drobbins 1.86 </p>
702 swift 1.149
703 drobbins 1.86 <p>
704     To begin, I'll introduce "block devices". The most famous block device is
705     probably the one that represents the first IDE drive in a Linux system:
706     </p>
707 swift 1.149
708 drobbins 1.86 <pre caption="/dev/hda, the block device representing the primary master IDE drive in your system">
709     /dev/hda
710     </pre>
711    
712     <p>
713     If your system uses SCSI drives, then your first hard drive will be:
714     </p>
715    
716     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
717     /dev/sda
718     </pre>
719    
720 swift 1.149 <p>
721     The block devices above represent an <e>abstract</e> interface to the disk.
722 drobbins 1.86 User programs can use these block devices to interact with your disk without
723 swift 1.149 worrying about whether your drives are IDE, SCSI or something else. The
724 drobbins 1.86 program can simply address the storage on the disk as a bunch of contiguous,
725 swift 1.149 randomly-accessible 512-byte blocks.
726     </p>
727    
728 drobbins 1.86 </body>

730     <section>
731     <title>Partitions and fdisk</title>
732     <body>
733    
734 swift 1.149 <p>
735     Under Linux, we create filesystems by using a special command called
736     <c>mkfs</c> (or <c>mke2fs</c>, <c>mkreiserfs</c>, etc.), specifying a particular
737     block device as a command-line argument.
738     </p>
739    
740     <p>
741     However, although it is theoretically possible to use a "whole disk" block
742     device (one that represents the <e>entire</e> disk) like <path>/dev/hda</path>
743     or <path>/dev/sda</path> to house a single filesystem, this is almost never
744     done in practice. Instead, full disk block devices are split up into smaller,
745     more manageable block devices called "partitions". Partitions are created
746     using a tool called <c>fdisk</c>, which is used to create and edit the
747     partition table that's stored on each disk. The partition table defines
748     exactly how to split up the full disk.
749     </p>
750    
751     <p>
752     We can take a look at a disk's partition table by running <c>fdisk</c>,
753     specifying a block device that represents a full disk as an argument:
754     </p>
755 drobbins 1.86
756 swift 1.149 <note>
757     Alternate interfaces to the disk's partition table include <c>cfdisk</c>,
758 swift 1.142 <c>parted</c> and <c>partimage</c>. We recommend <c>fdisk</c> because it's
759 swift 1.149 more powerful and well known in the Unix/Linux world.

814     This particular disk is configured to house seven Linux filesystems (each
815 drobbins 1.86 with a corresponding partition listed as "Linux") as well as a swap partition
816 swift 1.149 (listed as "Linux swap").
817     </p>
818 drobbins 1.86
819     <p>
820     Notice the name of the corresponding partition block
821 swift 1.149 devices on the left hand side, starting with <path>/dev/hda1</path> and going
822     up to <path>/dev/hda9</path>. In the early days of the PC, partitioning
823     software only allowed a maximum of four partitions (called "primary"
824     partitions). This was too limiting, so a workaround called <e>extended
825     partitioning</e> was created. An extended partition is very similar to a
826     primary partition and counts towards the primary partition limit of four.
827     However, extended partitions can hold any number of so-called <e>logical</e>
828     partitions inside them, providing an effective means of working around the
829     four partition limit.
830     </p>
831    
832     <p>
833     All partitions <path>/dev/hda5</path> and higher are logical partitions.
834     The numbers 1 through 4 are reserved for primary or extended partitions.
835 drobbins 1.86 </p>
836    
837     <p>
838 swift 1.149 So, In our example, <path>/dev/hda1</path> through <path>/dev/hda3</path> are
839     primary partitions. <path>/dev/hda4</path> is an extended partition that
840     contains logical partitions <path>/dev/hda5</path> through
841     <path>/dev/hda9</path>. You would never actually <e>use</e>
842     <path>/dev/hda4</path> for storing any filesystems directly -- it simply
843     acts as a container for partitions <path>/dev/hda5</path> through
844     <path>/dev/hda9</path>.
845     </p>
846 drobbins 1.86
847 swift 1.149 <p>
848     Also, notice that each partition has an "Id", also called a "partition
849 drobbins 1.86 type". Whenever you create a new partition, you should ensure that the
850     partition type is set correctly. '83' is the correct partition type for
851 swift 1.115 partitions that will be housing Linux filesystems, '82' is the correct

885    
886 swift 1.149 <p>
887     In our suggested "newbie" partition configuration, we have three partitions.
888     The first one (<path>/dev/hda1</path>) at the beginning of the disk is a small
889 drobbins 1.86 partition called a boot partition. The boot partition's purpose is to hold all
890     the critical data related to booting -- GRUB boot loader information (if you
891     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
892     us a safe place to store everything related to booting Linux. During normal
893     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
894 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
895 swift 1.149 likely end up being <path>/dev/sda1</path>.
896     </p>
897 drobbins 1.86
898 swift 1.149 <p>
899     It's recommended to have boot partitions (containing everything necessary for
900 drobbins 1.98 the boot loader to work) at the beginning of the disk. While not necessarily
901     required anymore, it is a useful tradition from the days when the lilo boot
902     loader wasn't able to load kernels from filesystems that extended beyond disk
903     cylinder 1024.
904     </p>
905    
906 swift 1.149 <p>
907     The second partition (<path>/dev/hda2</path>) is used to for swap space. The
908 drobbins 1.86 kernel uses swap space as virtual memory when RAM becomes low. This partition,
909     relatively speaking, isn't very big either, typically somewhere around 512MB.
910 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
911 swift 1.149 being called <path>/dev/sda2</path>.
912     </p>
913 drobbins 1.86
914 swift 1.149 <p>
915     The third partition (<path>/dev/hda3</path>) is quite large and takes up the
916     rest of the disk. This partition is called our "root" partition and will be
917     used to store your main filesystem that houses Gentoo Linux itself. On a SCSI
918     system, this partition would likely end up being <path>/dev/sda3</path>.

1123     Now that the partitions have been created, it's time to set up filesystems on
1124     the boot and root partitions so that they can be mounted and used to store
1125     data. We will also configure the swap partition to serve as swap storage.
1126 drobbins 1.86 </p>
1127    
1128 swift 1.149 <p>
1129     Gentoo Linux supports a variety of different types of filesystems; each type has
1130     its strengths and weaknesses and its own set of performance characteristics.
1131     Currently, we support the creation of ext2, ext3, XFS, JFS and ReiserFS
1132     filesystems.
1133     </p>
1134 drobbins 1.86
1135 swift 1.149 <p>
1136     ext2 is the tried and true Linux filesystem but doesn't have metadata
1137 drobbins 1.86 journaling, which means that routine ext2 filesystem checks at startup time can
1138     be quite time-consuming. There is now quite a selection of newer-generation
1139 swift 1.149 <e>journaled</e> filesystems that can be checked for consistency very quickly
1140 drobbins 1.86 and are thus generally preferred over their non-journaled counterparts.
1141     Journaled filesystems prevent long delays when you boot your system and your
1142 swift 1.149 filesystem happens to be in an <e>inconsistent</e> state.
1143     </p>
1144 drobbins 1.86
1145 swift 1.149 <p>
1146     ext3 is the journaled version of the ext2 filesystem, providing metadata
1147 drobbins 1.86 journaling for fast recovery in addition to other enhanced journaling modes
1148     like full data and ordered data journaling. ext3 is a very good and reliable
1149 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
1150     Because it does not extensively employ the use of "trees" in its internal
1151     design, it doesn't scale very well, meaning that it is not an ideal choice for
1152     very large filesystems, or situations where you will be handling very large
1153     files or large quantities of files in a single directory. But when used within
1154 swift 1.149 its design parameters, ext3 is an excellent filesystem.
1155     </p>
1156 drobbins 1.86
1157 swift 1.149 <p>
1158     ReiserFS is a B*-tree based filesystem that has very good overall
1159 drobbins 1.86 performance and greatly outperforms both ext2 and ext3 when dealing with small
1160     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
1161     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
1162     now rock-solid and highly recommended for use both as a general-purpose
1163     filesystem and for extreme cases such as the creation of large filesystems, the
1164 swift 1.149 use of many small files, very large files and directories containing tens of
1165 drobbins 1.86 thousands of files. ReiserFS is the filesystem we recommend by default for all
1166 swift 1.149 non-boot partitions.
1167     </p>
1168 drobbins 1.86
1169 swift 1.149 <p>
1170     XFS is a filesystem with metadata journaling that is fully supported under
1171     Gentoo Linux's <c>xfs-sources</c> kernel. It comes with a robust
1172 drobbins 1.86 feature-set and is optimized for scalability. We only recommend using this
1173     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
1174     a uninterruptible power supply. Because XFS aggressively caches in-transit data
1175     in RAM, improperly designed programs (those that don't take proper precautions
1176 swift 1.149 when writing files to disk and there are quite a few of them) can lose a good
1177     deal of data if the system goes down unexpectedly.
1178     </p>
1179 drobbins 1.86
1180 swift 1.149 <p>
1181     JFS is IBM's high-performance journaling filesystem. It has recently
1182     become production-ready and there hasn't been a sufficient track record to
1183 swift 1.142 comment positively nor negatively on its general stability at this
1184 swift 1.149 point.

1186 drobbins 1.86
1187 swift 1.149 <p>
1188     If you're looking for the most rugged journaling filesystem, use ext3. If
1189 drobbins 1.86 you're looking for a good general-purpose high-performance filesystem with
1190     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
1191 swift 1.149 refined and recommended for general use.

1193 drobbins 1.86

1646     The stage1 tarball is for complete customization and optimization. If you
1647     have picked this tarball, you are most likely looking to have an
1648     uber-optimized and up-to-date system. Have fun! Installing from a stage1
1649     takes a lot of time, but the result is a system that has been optimized
1650     from the ground up for your specific machine and needs.

1654     Now, it is time to start the "bootstrap" process. This process takes
1655     about two hours on a 1200MHz AMD Athlon system. During this time, the GNU
1656     C library, compiler suite and other key system programs will be built. Start
1657     the bootstrap as follows:

1669 swift 1.149 <note>
1670     <c>bootstrap.sh</c> now supports the <c>--fetchonly</c> option. Dial-up
1671     users will find this especially handy. It will download all bootstrap related
1672     files in one go for later compilation. See <c>bootstrap.sh -h</c> for more

1677     Portage by default uses <path>/var/tmp</path> during package building,
1678     often using several hundred megabytes of temporary storage. If you would
1679     like to change where Portage stores these temporary files, set a new
1680     PORTAGE_TMPDIR <e>before</e> starting the bootstrap process, as follows:

1688     and <c>glibc</c>, rebuilding <c>gettext</c> after <c>glibc</c>. Needless to
1689     say, this process takes a while. Once this process completes, your system
1690     will be equivalent to a "stage2" system, which means you can now move on to
1691     the stage2 instructions.

1771     <note>
1772     <b>Advanced users:</b> However, since the stage3 tarball is pre-built, it
1773     may be slightly out-of-date. If this is a concern for you, you can
1774     automatically update your existing stage3 to contain the most up-to-date
1775 swift 1.161 versions of all system packages by making a backup of
1776     <path>/etc/make.conf</path>, then typing <c>export CONFIG_PROTECT="-*"
1777     emerge -u system</c> (this requires a network connection) and replacing
1778     the backup afterwards. Note that this could take a long time if your stage3 is
1779     very old; otherwise, this process will generally be quick and will allow you
1780     to benefit from the very latest Gentoo updates and fixes. In any case, feel

1870     <title>Kernel selections</title>
1871     <body>
1872    
1873     <p>
1874     There are two options for installing a kernel. You can either configure your
1875     own kernel or use the <c>genkernel</c> utility to configure and compile your
1876     kernel automatically.
1877     </p>
1878    
1879     <p>
1880     Whether configuring a kernel by hand or using <c>genkernel</c>,
1881     you'll need to merge the Linux kernel sources you'd like to use.
1882     Gentoo provides several kernel ebuilds; a list can be found
1883     <uri link="/doc/en/gentoo-kernel.xml">here</uri>. If you are uncertain
1884     which kernel sources to choose, we advise using <c>gentoo-sources</c>.
1885     If you want XFS support, you should choose <c>xfs-sources</c> or
1886     <c>gs-sources</c>. Gentoo's LiveCD uses <c>gs-sources</c> and
1887     <c>xfs-sources</c>. There is also a <c>gaming-sources</c> kernel optimized
1888     for game-playing responsiveness that works wonderfully for this purpose when
1889     the "Preemptible kernel" option is enabled.
1890     </p>
1891    
1892     <p>
1893     Choose a kernel and then merge as follows:
1894     </p>
1895    
1896     <pre caption="Emerging Kernel Sources">

1899    
1900     <p>
1901     The <path>/usr/src/linux</path> symbolic link will point to your
1902     newly-installed kernel source tree. Portage uses the
1903     <path>/usr/src/linux</path> symbolic link for a special purpose. Any ebuilds
1904     you install that contain kernel modules will be configured to work with the
1905     kernel source tree pointed to by <path>/usr/src/linux</path>.
1906     <path>/usr/src/linux</path> is created when you emerge your first kernel
1907     source package, but after it exists, Portage does not modify this symbolic
1908     link.

1914     <title>Using genkernel to compile your kernel</title>
1915     <body>
1916    
1917     <p>
1918     Now that your kernel source tree is installed, it's now time to compile your
1919     kernel. There are two ways to do this. The first way is to use our new
1920     <c>genkernel</c> script to automatically build a kernel for you.
1921     <c>genkernel</c> works by configuring a kernel nearly identically to the way
1922     our LiveCD kernel is configured. This means that when you use <c>genkernel</c>
1923     to build your kernel, your system will generally detect all your hardware at
1924     boot-time, just like our Live CD does. Because genkernel doesn't require any
1925     manual kernel configuration, it is an ideal solution for those users who may
1926     not be comfortable compiling their own kernels.
1927     </p>
1928    
1929     <p>
1930     Now, let's see how to use genkernel. First, emerge the genkernel ebuild:

1938     Now, compile your kernel sources by running <c>genkernel</c>:

1940    
1941     <note>
1942     <b>Advanced users:</b> you can type <c>genkernel --config</c> instead,
1943     which will cause genkernel to allow you to tweak the default kernel
1944     configuration before building begins.

1980     <p>
1981     Once <c>genkernel</c> completes, a kernel, full set of modules and
1982     <e>initial root disk</e> (initrd) will be created. We will use the kernel
1983 swift 1.161 and initrd when configuring a boot loader later in this document. Write
1984     down the names of the kernel and initrd as you will need it when writing
1985     the bootloader configuration file. The initrd will be started immediately after
1986     booting to perform hardware autodetection (just like on the Live CD) before
1987     your "real" system starts up.
1988 swift 1.149 </p>
1989    
1990     <p>
1991     Now, let's perform one more step to get our system to be more like the Live
1992     CD -- let's emerge <c>hotplug</c>. While the initrd autodetects hardware that
1993     is needed to boot your system, <c>hotplug</c> autodetects everything else.
1994     To emerge and enable <c>hotplug</c>, type the following:

2089     If you use PPPoE to connect to Internet, you will need the following
2090     options in the kernel (built-in or as preferably as modules) : &quot;PPP
2091     (point-to-point protocol) support&quot;, &quot;PPP support for async serial
2092     ports&quot;, &quot;PPP support for sync tty ports&quot;. The two compression
2093     options won't harm but are not definitely needed, neither does the &quot;PPP
2094     over Ethernet&quot; option, that might only be used by <c>rp-pppoe</c> when
2095     configured to do kernel mode PPPoE.
2096     </p>
2097    
2098     <p>
2099     If you have an IDE cd burner, then you need to enable SCSI emulation in the
2100     kernel. Turn on &quot;ATA/IDE/MFM/RLL support&quot; ---&gt; &quot;IDE, ATA
2101     and ATAPI Block devices&quot; ---&gt; &quot;SCSI emulation support&quot;
2102     (I usually make it a module), then under &quot;SCSI support&quot; enable
2103     &quot;SCSI support&quot;, &quot;SCSI CD-ROM support&quot; and &quot;SCSI
2104     generic support&quot; (again, I usually compile them as modules). If you
2105     also choose to use modules, then <c>echo -e &quot;ide-scsi\nsg\nsr_mod&quot;
2106 swift 1.157 &gt;&gt; /etc/modules.autoload.d/kernel-2.4</c> to have them automatically
2107     added at boot time.
2108 swift 1.149 </p>
2109    
2110     <p>
2111     If you require it, don't forget to include support in the kernel for your
2112     ethernet card.
2113     </p>
2114    
2115     <note>
2116     For those who prefer it, it is possible to install Gentoo Linux with a 2.2
2117     kernel. However, doing this comes at a price: you will lose many of the nifty
2118     features that are new to the 2.4 series kernels (such as XFS and tmpfs
2119     filesystems, iptables and more), although the 2.2 kernel sources can be
2120     patched with ReiserFS and devfs support.
2121     Gentoo linux boot scripts require either tmpfs or ramdisk support in the
2122     kernel, so 2.2 kernel users need to make sure that ramdisk support is compiled
2123     in (ie, not a module). It is <comment>vital</comment> that a
2124     <e>gentoo=notmpfs</e> flag be added to the kernel line in
2125     <path>/boot/grub/grub.conf</path> or to the append line in
2126     <path>/etc/lilo.conf</path> for the 2.2 kernel so that a ramdisk is mounted
2127     for the boot scripts instead of tmpfs. If you choose not to use devfs, then
2128     <e>gentoo=notmpfs,nodevfs</e> should be used instead.

2212     <title>Installing a system logger</title>
2213     <body>
2214 swift 1.149
2215     <p>
2216     Your new custom kernel (and modules) are now installed. Now you need to choose
2217     a system logger that you would like to install. We offer sysklogd, which is
2218     the traditional set of system logging daemons. We also have msyslog and
2219     syslog-ng as well as metalog. Power users seem to gravitate away from
2220     sysklogd (not very good performance) and towards the newer alternatives.
2221     If in doubt, you may want to try metalog, since it seems to be quite popular.
2222     To merge your logger of choice, type <e>one</e> of the next four command
2223     sets:
2224     </p>

2241     Metalog flushes output to the disk in blocks, so messages aren't immediately
2242     recorded into the system logs. If you are trying to debug a daemon, this
2243     performance-enhancing behavior is less than helpful. When your Gentoo Linux
2244     system is up and running, you can send metalog a USR1 signal to temporarily
2245     turn off this message buffering (meaning that <c>tail -f
2246     <path>/var/log/everything/current</path></c> will now work in real time, as
2247     expected) and a USR2 signal to turn buffering back on again. If you want to
2248     disable buffering permanently, you can change METALOG_OPTS="-B" to
2249     METALOG_OPTS="-B -s" in <path>/etc/conf.d/metalog</path>.

2552     <p>
2553     In the spirit of Gentoo, users now have more than one bootloader to choose
2554     from. Using our virtual package system, users are now able to choose between
2555     both GRUB and LILO as their bootloaders.
2556     </p>
2557    
2558     <p>
2559     Please keep in mind that having both bootloaders installed is not necessary.
2560     In fact, it can be a hindrance, so please only choose one.
2561     </p>
2562    
2563     <p>
2564     In addition, you will need to configure our bootloader differently depending
2565     upon whether you are using <c>genkernel</c> (with kernel and initrd) or a
2566     kernel you compiled by hand. Be sure to take note of the important
2567     differences.

2571     If you are installing Gentoo Linux on a system with an NVIDIA nForce or
2572     nForce2 chipset with an integrated GeForce graphics card, you should use
2573     LILO and avoid GRUB. With on-board video enabled, the low memory area of your
2574     RAM may be used as video RAM. Since GRUB also uses low memory at boot time,
2575     it may experience an "out of memory" condition. So, if you have an nForce
2576     or potentially other board with on-board video, use LILO. Even if you're using
2577     off-board video right now, it would be nice to be able to remove the graphics
2578     card and use the on-board video in a pinch, wouldn't it? :)

2584     <title>Configuring GRUB</title>
2585     <body>
2586    
2587     <p>
2588     The most critical part of understanding GRUB is getting comfortable with how
2589     GRUB refers to hard drives and partitions. Your Linux partition
2590     <path>/dev/hda1</path> is called <path>(hd0,0)</path> under GRUB. Notice the
2591     parenthesis around the hd0,0 - they are required. Hard drives count from zero
2592     rather than "a" and partitions start at zero rather than one. Be aware too
2593     that with the hd devices, only hard drives are counted, not atapi-ide devices
2594     such as cdrom players, burners and that the same construct can be used with
2595     scsi drives. (Normally they get higher numbers than ide drives except when the
2596     bios is configured to boot from scsi devices.) Assuming you have a hard drive
2597     on <path>/dev/hda</path>, a cdrom player on <path>/dev/hdb</path>, a burner on
2598     <path>/dev/hdc</path>, a second hard drive on <path>/dev/hdd</path> and no
2599     SCSI hard drive, <path>/dev/hdd7</path> gets translated to
2600     <path>(hd1,6)</path>. It might sound tricky and tricky it is indeed, but as
2601     we will see, GRUB offers a tab completion mechanism that comes handy for
2602     those of you having a lot of hard drives and partitions and who are a little
2603     lost in the GRUB numbering scheme. Having gotten the feel for that, it is
2604     time to install GRUB.
2605     </p>
2606    
2607     <p>
2608     The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted
2609     shell prompt:
2610     </p>
2611    
2612 jhhudso 1.81 <pre caption="Installing GRUB">
2613 swift 1.149 # <i>emerge -k grub</i>
2614     # <i>grub</i>
2615 jhhudso 1.81 </pre>
2616 swift 1.149
2617     <p>
2618     You will be presented with the <e>grub&gt;</e> grub command-line prompt.
2619     Now, you need to type in the right commands to install the GRUB boot record
2620     onto your hard drive. In my example configuration, I want to install the GRUB
2621     boot record on my hard drive's MBR (master boot record), so that the first
2622     thing I see when I turn on the computer is the GRUB prompt. In my case, the
2623     commands I want to type are:
2624     </p>
2625 zhen 1.68
2626 jhhudso 1.81 <pre caption="GRUB on the MBR">
2627 swift 1.149 grub&gt; <i>root (hd0,0)</i> <comment>(Your boot partition)</comment>
2628     grub&gt; <i>setup (hd0)</i> <comment>(Where the boot record is installed; here, it is the MBR)</comment>

2630 zhen 1.68
2631 jhhudso 1.81 <pre caption="GRUB not on the MBR">
2632 swift 1.149 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR:</comment>

2634     grub&gt; <i>setup (hd0,4)</i> <comment>(Where the boot record is installed; here it is /dev/hda5)</comment>
2635     grub&gt; <i>quit</i>
2636     </pre>
2637    
2638     <p>
2639     Here is how the two commands work. The first <c>root ( )</c> command tells
2640     GRUB the location of your boot partition (in our example,
2641     <path>/dev/hda1</path> or <path>(hd0,0)</path> in GRUB terminology. Then, the
2642     second <c>setup ( )</c> command tells GRUB where to install the boot record -
2643     it will be configured to look for its special files at the <c>root ( )</c>
2644     location that you specified. In my case, I want the boot record on the MBR
2645     of the hard drive, so I simply specify <path>/dev/hda</path> (also known as
2646     <path>(hd0)</path>). If I were using another boot loader and wanted to set up
2647     GRUB as a secondary boot-loader, I could install GRUB to the boot record of
2648     a particular partition. In that case, I would specify a particular partition
2649     rather than the entire disk. Once the GRUB boot record has been successfully
2650     installed, you can type <c>quit</c> to quit GRUB.
2651     </p>
2652    
2653     <note>
2654     The tab completion mechanism of GRUB can be used from within GRUB,
2655     assuming you wrote <c> root (</c> and that you hit the TAB key, you would
2656     be prompted with a list of the available devices (not only hard drives),
2657     hitting the TAB key having written <c> root (hd</c>, GRUB would print the
2658     available hard drives and hitting the TAB key after writing <c> root (hd0,</c>
2659     would make GRUB print the list of partitions on the first hard drive.
2660     Checking the syntax of the GRUB location with completion should really help
2661     to make the right choice.

2665     Gentoo Linux is now installed, but we need to create the
2666     <path>/boot/grub/grub.conf</path> file so that we get a nice GRUB boot menu
2667     when the system reboots. Here is how to do it.

2671     To ensure backwards compatibility with GRUB, make sure to make a link from

2725     <note>
2726     Above, <path>(hd0,0)</path> should point to your "boot" partition

2733     The path to the kernel image is relative to the boot partition. If for
2734     example you have separated boot partition <path>(hd0,0)</path> and root
2735     partition <path>(hd0,1)</path>, all paths in the <path>grub.conf</path> file
2736     above will become <path>/bzImage</path>.

2739     <p>
2740     If you need to pass any additional options to the kernel, simply add them to
2741     the end of the <c>kernel</c> command. We're already passing one option
2742     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you
2743     can turn off devfs by default (not recommended unless you know what you're
2744     doing) by adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c>
2745     command.
2746     </p>
2747    
2748     <note>
2749     Unlike in earlier versions of Gentoo Linux, you no longer have to add
2750     <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs.
2751     Now devfs is enabled by default.

2760     <p>
2761     While GRUB may be the new alternative for most people, it is not always the
2762     best choice. LILO, the LInuxLOader, is the tried and true workhorse of Linux
2763     bootloaders. Here is how to install LILO if you would like to use it instead
2764     of GRUB.

2933    
2934     <p>
2935     GRP users can, at this point, install binary packages:
2936     </p>
2937 swift 1.142
2938     <pre caption="Installing from GRP">
2939 swift 1.149 # <i>USE="bindist" emerge -k xfree</i>

2941 swift 1.142 </pre>
2942    
2943 swift 1.149 <p>
2944     CD 1 contains enough applications to install a working system with XFree86.
2945     Additionally, CD2 of the 2-CD GRP set contains other applications including
2946     KDE, GNOME, Mozilla and others. To install these packages, you will need to
2947     reboot into your new Gentoo system first (covered in the "Installation
2948     complete!" section near the end of this document). After you are running your
2949     basic Gentoo system from the hard drive, you can mount the second CD and copy
2950     files:
2951     </p>
2952 swift 1.142
2953 swift 1.149 <pre caption="Loading binary packages from CD2">
2954     # <i>mount /dev/cdrom /mnt/cdrom</i>

2956 swift 1.142 </pre>
2957    
2958 swift 1.149 <p>
2959     Now various other applications can be installed the same way. For example:

2976     Now, Gentoo Linux is installed. The only remaining step is to update necessary
2977     configuration files, exit the chrooted shell, safely unmount your partitions
2978     and reboot the system:
2979     </p>
2980 jhhudso 1.75
2981 swift 1.142 <warn>
2982     <c>etc-update</c> can provide you with a list of configuration files
2983     that have newer versions at your disposal. Verify that none of the
2984     configuration files have a big impact (such as <path>/etc/fstab</path>,
2985     <path>/etc/make.conf</path>, <path>/etc/rc.conf</path>, ...). Merge the
2986     files that don't have such a big impact, remove the updates of the
2987     others or view the diff and manually update the configuration file.

3003     After rebooting, it is a good idea to run the <c>update-modules</c> command to
3004     create the <path>/etc/modules.conf</path> file. Instead of modifying this
3005     file directly, you should generally make changes to the files in
3006     <path>/etc/modules.d</path>.

3033     <title>Gentoo-Stats</title>
3034     <section>
3035     <body>
3036    
3037     <p>
3038     The Gentoo Linux usage statistics program was started as an attempt to give
3039     the developers a way to find out about their user base. It collects information
3040     about Gentoo Linux usage to help us in set priorities our development.
3041     Installing it is completely optional and it would be greatly appreciated if
3042     you decide to use it. Compiled statistics can be viewed at
3043     <uri>http://stats.gentoo.org/</uri>.
3044     </p>
3045    
3046     <p>
3047     The gentoo-stats server will assign a unique ID to your system.
3048     This ID is used to make sure that each system is counted only once. The ID
3049     will not be used to individually identify your system, nor will it be matched
3050     against an IP address or other personal information. Every precaution has been
3051     taken to assure your privacy in the development of this system. The following
3052     are the things that we are monitoring right now through our "gentoo-stats"
3053     program:
3054     </p>
3055    
3056     <ul>
3057     <li>installed packages and their version numbers</li>
3058     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like "mmx" or "3dnow")</li>
3059     <li>memory information (total available physical RAM, total available swap space)</li>
3060     <li>PCI cards and network controller chips</li>
3061     <li>the Gentoo Linux profile your machine is using (that is, where the <path>/etc/make.profile</path> link is pointing to).</li>
3062     </ul>
3063    
3064     <p>
3065     We are aware that disclosure of sensitive information is a threat to most
3066     Gentoo Linux users (just as it is to the developers).
3067     </p>
3068    
3069     <ul>
3070     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive information such as your passwords, configuration data, shoe size...</li>
3071     <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
3072     <li>The IP address your data transmission originates from will never be logged in such a way that we can identify you. There are no "IP address/system ID" pairs.</li>
3073     </ul>
3074    
3075     <p>
3076     The installation is easy - just run the following commands:
3077     </p>
3078    
3079 jhhudso 1.81 <pre caption="Installing gentoo-stats">
3080 swift 1.149 # <i>emerge gentoo-stats</i> <comment>(Installs gentoo-stats)</comment>
3081     # <i>gentoo-stats --new</i> <comment>(Obtains a new system ID)</comment>
3082 jhhudso 1.81 </pre>
3083 swift 1.149
3084     <p>
3085     The second command above will request a new system ID and enter it into
3086     <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view
3087     this file to see additional configuration options.
3088     </p>
3089    
3090     <p>
3091     After that, the program should be run on a regular schedule (gentoo-stats does
3092     not have to be run as root). Add this line to your <path>crontab</path>:
3093     </p>
3094    
3095 jhhudso 1.81 <pre caption="Updating gentoo-stats with cron">
3096 swift 1.149 0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null
3097 jhhudso 1.81 </pre>
3098 swift 1.149
3099     <p>
3100     The <c>gentoo-stats</c> program is a simple perl script which can be
3101     viewed with your favorite pager or editor: <path>/usr/sbin/gentoo-stats</path>.

3114     <p>
3115     Users who want to install Gentoo on Hardware ATA RAID must pay
3116     attention to the next steps in order for them to succesfully
3117     install Gentoo Linux:
3118     </p>
3119    
3120     <ul>
3121     <li>Be sure to start the LiveCD with the <c>doataraid</c> kerneloption.</li>
3122     <li>If you've forgotten to select <c>doataraid</c> during bootup, or the modules mysteriously didn't load, load them as needed:
3123     <pre caption = "Loading RAID modules">
3124 swift 1.137 # <i>modprobe ataraid</i>
3125     <comment>For Promise Raid Controllers:</comment>
3126     # <i>modprobe pdcraid</i>
3127     <comment>For Highpoint Raid Controllers:</comment>
3128 swift 1.138 # <i>modprobe hptraid</i>
3129 swift 1.149 </pre></li>
3130     <li>Some ATA RAID Controllers require you to reboot after partitioning; formatting will otherwise fail.</li>
3131     <li>Before chrooting, mount the devicetree into the new environment:
3132     <pre caption = "Mounting /dev into /mnt/gentoo/dev">
3133 swift 1.137 # <i>mount -o bind /dev /mnt/gentoo/dev</i>
3134 swift 1.149 </pre></li>
3135     <li>During kernel configuration, select the required RAID options:
3136     <pre caption = "RAID in the Linux Kernel Configuration">
3137 swift 1.137 <comment>For Highpoint RAID controllers:</comment>
3138     ATA/IDE/MFM/RLL support ---&gt;

3149     </pre></li>
3150     <li>When using GRUB add <c>--stage2=/boot/grub/stage2</c> when running <c>grub</c> to the <c>setup</c> command:
3151     <pre caption = "Installing GRUB for Hardware RAID systems">
3152 swift 1.137 grub&gt; <i>root (hd0,0)</i>
3153     grub&gt; <i>setup --stage2=/boot/grub/stage2 (hd0)</i>
3154     grub&gt; <i>quit</i>
3155 swift 1.149 </pre>
3156     Also, in the GRUB configuration be sure to point the <c>root</c>
3157     to the appropriate RAID device:
3158     <pre caption = "grub.conf for RAID">
3159 swift 1.137 title=My Gentoo Linux on RAID
3160     root (hd0,0)
3161     kernel (hd0,0)/boot/bzImage root=/dev/ataraid/dXpY
3162 swift 1.149 </pre></li>
3163     <li>LILO users should set the <c>root</c> option to the appropriate RAID device:
3164     <pre caption = "lilo.conf for RAID">
3165 swift 1.137 image=/boot/bzImage
3166 swift 1.149 label=linux
3167     read-only
3168     root=/dev/ataraid/dXpY
3169     </pre></li>
3170     </ul>
3171    
3172 swift 1.153 <p>
3173     If you still have problems installing Gentoo Linux on your Hardware
3174     RAID, be sure to report them on <uri>http://bugs.gentoo.org</uri>.
3175     </p>
3176    
3177     <p>
3178     Thanks for using Gentoo Linux, and have fun with your new installation!
