55 zhen 1.16 <abstract>These instructions step you through the process of installing Gentoo
56 swift 1.142 Linux 1.4, release version (not _rc versions.) The Gentoo Linux installation process supports various installation
57 zhen 1.6 approaches, depending upon how much of the system you want to custom-build from
58     scratch.

66     <title>About the Install</title>
67     <section>
68     <body>
69 swift 1.142 <p>First, if you are new to this, welcome to Gentoo Linux! Gentoo
70     Linux can be installed in many different ways. Those who are looking
71     for a rapid install can use pre-built packages, while those who want
72     the ultimate in customizability can compile Gentoo Linux entirely
73     from the original source code. The method you choose is up to
74     you.</p>
75    
76     <p>One significant change in relation to the official 1.4 release is
77     our new 2-CD installation set, which can be ordered from <uri
78     link="http://store.gentoo.org">The Gentoo Linux Store</uri>, in
79     addition to being available on our mirrors. We currently have 2-CD
80     installation sets for x86 (486 and above), i686 (Pentium Pro,
81     Pentium II, Athlon/Duron and above), Pentium III, Pentium 4, and Athlon XP.
82     To see what 2-CD set is right for you, read the detailed
83     descriptions of each product in the <uri
84     link="http://store.gentoo.org">store</uri>. The store descriptions
85     contain fairly comprehensive CPU compatibility information.</p>
86    
87     <p>So, about the 2 CD set -- here's what's on each CD. The first
88     CD ("CD 1") is called "Live CD Installation," and is a bootable CD-ROM,
89     meaning that you can put "CD 1" in your drive and run Gentoo Linux
90     directly from the CD. You can then use this CD-based version of
91     Gentoo to install Gentoo Linux 1.4 to your hard disk. In addition
92     to containing a bootable Gentoo Linux environment, every CD 1
93     contains everything you need to install Gentoo Linux quickly, even
94     without a connection to the Internet. In addition, several
95     pre-compiled packages are also included on CD 1, such as the
96     ever-important XFree86 X server. If you have an ISO CD-ROM image
97     file for CD 1, its name will end in "-cd1.iso".</p>
98    
99     <p>In contrast, the second CD ("CD 2") isn't bootable, and contains
100     lots of pre-built packages for your system. Included on this CD are
101     optimized versions of packages such as KDE, GNOME, OpenOffice,
102     Mozilla, Evolution, and others. CD 2 is <i>optional</i> and is
103     intended for those people who are interested in installing Gentoo
104     Linux very quickly. The packages included on CD 2 typically take
105     about 36 hours to compile from source on a typical modern
106     single-processor system. If you have an ISO CD-ROM image file for CD
107     2, its name will end in "-cd2.iso". </p>
108    
109     <note>A complete Gentoo Linux 2-CD set contains the Gentoo Reference
110     Platform, which is a complete pre-built Gentoo Linux system including GNOME,
111     KDE, Mozilla, and OpenOffice. The Gentoo Reference Platform ("GRP")
112     was created to allow rapid Gentoo Linux installs
113     packages for those who need this capability. The "compile from
114     source" functionality, which is the cornerstone of Gentoo Linux,
115     will always be a fully-supported installation option as well. The
116     purpose of the GRP is to make Gentoo Linux more convenient for some
117     users, without impacting Gentoo's powerful "compile from source"
118     installation process in any way.</note>
119    
120     <p>In addition to our 2-CD set, we also have a very small "basic"
121     Live CD that you can use to boot your system. Once your system has
122     booted, you can configure a connection to the Internet and then
123     install Gentoo over the network. The advantage of this "basic" CD is
124     that it is small, and thus the ISO CD-ROM image file can be
125     downloaded quickly. If you're an advanced user who wants to install
126     the most up-to-date version of Gentoo Linux available, and have a
127     fast network connection, then you may prefer this option. If you
128     have an ISO CD-ROM image file for our "basic" Live CD, its name will
129     end in "-basic.iso".</p>
130 drobbins 1.70
131 swift 1.142 <p>To use any Gentoo Linux CD-based installation method, you will
132     need to have a 486+ processor and ideally at least 64 Megabytes of
133     RAM. (Gentoo Linux has been successfully built with 64MB of RAM +
134     64MB of swap space, but the build process is awfully slow under
135     those conditions.)</p>
136    
137     <p>Once you boot one of our Live CDs, you have even more options.
138     Gentoo Linux can be installed using one of three &quot;stage&quot;
139     tarball files. The one you choose depends on how much of the system
140     you want to compile yourself. The stage1 tarball is used when you
141     want to bootstrap and build the entire system from scratch. The
142     stage2 tarball is used for building the entire system from a
143     bootstrapped "semi-compiled" state. The stage3 tarball already
144     contains a basic Gentoo Linux system that has been built for
145     you. If you are interested in doing a "GRP" install, then the
146     stage3 tarball should be used.</p>
147    
148     <p><b>If you're not doing a GRP install, should you start from a stage1, stage2, or
149     stage3 tarball?</b> Here is some information that should help you
150     make this decision.
151     Starting from a stage1 allows you to have total
152     control over the optimization settings and optional build-time
153     functionality that is initially enabled on your system. This makes
154     stage1 installs good for power users who know what they are doing.
155     It is also a great installation method for those who want to more
156     about the inner workings of Gentoo Linux.</p>
157    
158     <p>
159     Stage2 installs allow you to skip the bootstrap process, and doing
160     this is fine if you are happy with the optimization settings that we
161     chose for your particular stage2 tarball. And choosing to go with a
162     stage3 allows for the fastest install of Gentoo Linux, but also
163     means that your base system will have the optimization settings that
164     we chose for you (which to be honest, are good settings and were
165     carefully chosen to enhance performance while maintaining
166     stability.) Since major releases of Gentoo Linux have stage3's
167     specifically optimized for various popular processors, starting
168     from a stage3 can offer the best of all worlds -- a fast install
169     and a system that is well-optimized.
170     <b>If you're installing Gentoo Linux for the
171     first time, consider using a stage3 tarball for
172     installation, or a stage3 with GRP.</b></p>
173 drobbins 1.70
174 swift 1.142 <note><b>Advanced users:</b> if you use a stage3 install, you should not
175     change the default CHOST setting in make.conf. If you need to make
176     such a change, you should start with a stage1 tarball and build up
177     your system with the desired CHOST setting. The CHOST setting
178     typically looks something like this:
179     <c>i686-pc-linux-gnu</c>.</note>
180    
181 drobbins 1.70 <impo>If you encounter a problem with any part of the install and wish to
182 drobbins 1.21 report it as a bug, report it to <uri>http://bugs.gentoo.org</uri>. If the bug
183 jhhudso 1.75 needs to be sent upstream to the original software developers (eg the KDE team) the
184 drobbins 1.70 <e>Gentoo Linux developers</e> will take care of that for you.
185     </impo>
186 swift 1.142
187     <note>Another note: the installation instructions in the LiveCD may not
188     be as up-to-date as our Web documentation at
189     <uri>http://www.gentoo.org/doc/en/gentoo-x86-install.xml</uri>. Refer to
190     our Web documentation for the most up-to-date
191 peesh 1.127 installation instructions.
192     </note>
193 swift 1.142
194    
195    
196     <p>Now, let us quickly review the install process. First, we will
197     download, burn CD(s),
198 jhhudso 1.75 and boot a LiveCD. After getting a root prompt, we will create partitions, create
199 drobbins 1.21 our filesystems, and extract either a stage1, stage2 or stage3 tarball. If we
200     are using a stage1 or stage2 tarball, we will take the appropriate steps to get
201 jhhudso 1.75 our system to stage3. Once our system is at stage3, we can configure it
202 swift 1.142 (customize configuration files, install a boot loader, etc), boot it and have a
203     fully-functional Gentoo Linux system. After your basic Gentoo Linux system
204     is running, you can optionally use "CD 2" of our 2-CD set and install any
205     number of pre-built packages such as KDE, GNOME, OpenOffice, Mozilla, or
206     others that you'd like on your system.
207     </p>
208     <p>Depending on what stage of the build

259 swift 1.142
260     <p>Start by booting your Live CD of choice. You should see a fancy
261     boot screen with the Gentoo Linux logo on it. At this screen, you
262     can hit Enter to begin the boot process, or boot the LiveCD with
263     custom boot options by specifying a kernel followed by boot options
264     and then hitting Enter. For example <c>gentoo nousb nohotplug</c>.
265     If you are installing Gentoo Linux on a system with more than one
266     processor ("SMP",) then you should type <c>smp</c> instead of
267     <c>gentoo</c> at the prompt. This will allow the LiveCD to see all
268     the processors in your system, not just the first one.</p>

372 swift 1.142 <p>When the Live CD boots, it tries to detect all your hardware
373     devices and loads the appropiate kernel modules to support your
374     hardware. In the vast majority of cases, it does a very good job.
375     However, in some cases, it may not auto-load the kernel modules
376     you need. If the PCI auto-detection missed some of your system's hardware, you
377 jhhudso 1.75 will have to load the appropriate kernel modules manually.
378 zhen 1.6 To view a list of all available network card modules, type <c>ls
379 swift 1.142 /lib/modules/`uname -r`/kernel/drivers/net/*</c>. To load a particular module,

386 drobbins 1.70 <p>Likewise, if you want to be able to access any SCSI hardware that wasn't detected
387 jhhudso 1.75 during the initial boot autodetection process, you will need to load the appropriate

576 drobbins 1.86 <title>Introduction to block devices</title>
577 zhen 1.16 <body>
578 drobbins 1.86 <p>
579     In this section, we'll take a good look at disk-oriented aspects of Gentoo Linux and Linux in general, including
580 peesh 1.99 Linux filesystems, partitions and block devices. Then, once you're familiar with the ins and outs of disks and
581 drobbins 1.86 filesystems, you'll be guided through the process of setting up partitions and filesystems for your Gentoo Linux
582     install.
583     </p>
584     <p>
585     To begin, I'll introduce "block devices". The most famous block device is
586     probably the one that represents the first IDE drive in a Linux system:
587     </p>
588     <pre caption="/dev/hda, the block device representing the primary master IDE drive in your system">
589     /dev/hda
590     </pre>
591    
592     <p>
593     If your system uses SCSI drives, then your first hard drive will be:
594     </p>
595    
596     <pre caption="/dev/sda, the block device representing the first logical SCSI drive in your system">
597     /dev/sda
598     </pre>
599    
600     <p>The block devices above represent an <i>abstract</i> interface to the disk.
601     User programs can use these block devices to interact with your disk without
602     worrying about whether your drivers are IDE, SCSI or something else. The
603     program can simply address the storage on the disk as a bunch of contiguous,
604     randomly-accessible 512-byte blocks. </p>
605     </body>
606     </section>
607     <section>
608     <title>Partitions and fdisk</title>
609     <body>
610     <p> Under Linux, we create filesystems by using a special command called
611     <c>mkfs</c> (or <c>mke2fs</c>, <c>mkreiserfs</c>, etc,) specifying a particular
612     block device as a command-line argument. </p>
613    
614     <p> However, although it is theoretically possible to use a "whole disk" block
615     device (one that represents the <i>entire</i> disk) like <c>/dev/hda</c> or
616     <c>/dev/sda</c> to house a single filesystem, this is almost never done in
617     practice. Instead, full disk block devices are split up into smaller, more
618 peesh 1.99 manageable block devices called "partitions". Partitions are created using a
619 drobbins 1.86 tool called <c>fdisk</c>, which is used to create and edit the partition table
620     that's stored on each disk. The partition table defines exactly how to split
621     up the full disk. </p>
622    
623     <p> We can take a look at a disk's partition table by running <c>fdisk</c>,
624     specifying a block device that represents a full disk as an argument: </p>
625    
626     <note>Alternate interfaces to the disk's partition table include <c>cfdisk</c>,
627 swift 1.142 <c>parted</c> and <c>partimage</c>. We recommend <c>fdisk</c> because it's
628     more powerful and well known in the Unix/Linux world.</note>

680     <p> This particular disk is configured to house seven Linux filesystems (each
681     with a corresponding partition listed as "Linux") as well as a swap partition
682     (listed as "Linux swap"). </p>
683    
684     <p>
685     Notice the name of the corresponding partition block
686     devices on the left hand side, starting with <c>/dev/hda1</c> and going up to
687     <c>/dev/hda9</c>. In the early days of the PC, partitioning software only
688     allowed a maximum of four partitions (called "primary" partitions). This was
689     too limiting, so a workaround called an <i>extended partitioning</i> was
690     created. An extended partition is very similar to a primary partition, and
691     counts towards the primary partition limit of four. However, extended
692     partitions can hold any number of so-called <i>logical</i> partitions inside
693     them, providing an effective means of working around the four partition limit.
694     </p>
695    
696     <p>
697     All partitions <c>hda5</c> and higher are logical partitions. The numbers 1
698     through 4 are reserved for primary or extended partitions. </p>
699    
700     <p> So, In our example, <c>hda1</c> through <c>hda3</c> are primary partitions.
701     <c>hda4</c> is an extended partition that contains logical partitions
702 drobbins 1.87 <c>hda5</c> through <c>hda9</c>. You would never actually
703 drobbins 1.86 <i>use</i> <c>/dev/hda4</c> for storing any filesystems directly -- it simply
704     acts as a container for partitions <c>hda5</c> through <c>hda9</c>. </p>
705    
706     <p> Also, notice that each partition has an "Id", also called a "partition
707     type". Whenever you create a new partition, you should ensure that the
708     partition type is set correctly. '83' is the correct partition type for
709 swift 1.115 partitions that will be housing Linux filesystems, '82' is the correct
710     partition type for Linux swap partitions and 'fd' is the recommended partition
711     type for Software RAID partitions. You set the partition type using the
712 drobbins 1.86 <c>t</c> option in <c>fdisk</c>. The Linux kernel uses the partition type
713 peesh 1.99 setting to auto-detect filesystems and swap devices on the disk at boot-time.

722 drobbins 1.86 done under Linux, it's time to walk you through the process of setting up disk
723     partitions for your Gentoo Linux installation. After we walk you through the
724     process of creating partitions on your disk, your partition configuration will
725     look like this: </p>
726    
727     <pre caption="The partition configuration that you will have after following these steps">

737     Command (m for help):
738     </pre>
739    
740     <p>In our suggested "newbie" partition configuration, we have three partitions.
741     The first one (<c>/dev/hda1</c>) at the beginning of the disk is a small
742     partition called a boot partition. The boot partition's purpose is to hold all
743     the critical data related to booting -- GRUB boot loader information (if you
744     will be using GRUB) as well as your Linux kernel(s). The boot partition gives
745     us a safe place to store everything related to booting Linux. During normal
746     day-to-day Gentoo Linux use, your boot partition should remain <e>unmounted</e>
747 drobbins 1.87 for safety. If you are setting up a SCSI system, your boot partition will
748     likely end up being <c>/dev/sda1</c>.</p>
749 drobbins 1.86
750 drobbins 1.98 <p>It's recommended to have boot partitions (containing everything necessary for
751     the boot loader to work) at the beginning of the disk. While not necessarily
752     required anymore, it is a useful tradition from the days when the lilo boot
753     loader wasn't able to load kernels from filesystems that extended beyond disk
754     cylinder 1024.
755     </p>
756    
757 drobbins 1.86 <p>The second partition (<c>/dev/hda2</c>) is used to for swap space. The
758     kernel uses swap space as virtual memory when RAM becomes low. This partition,
759     relatively speaking, isn't very big either, typically somewhere around 512MB.
760 drobbins 1.87 If you're setting up a SCSI system, this partition will likely end up
761     being called <c>/dev/sda2</c>. </p>
762 drobbins 1.86
763     <p>The third partition (<c>/dev/hda3</c>) is quite large and takes up the rest
764     of the disk. This partition is called our "root" partition and will be used to
765     store your main filesystem that houses Gentoo Linux itself. On a SCSI system,
766     this partition would likely end up being <c>/dev/sda3</c>.</p>
767    
768    
769     <p>Before we partition the disk, here's a quick technical overview of the
770     suggested partition and filesystem configuration to use when installing Gentoo
771     Linux:</p>

941     <title>Creating filesystems</title>
942     <body>
943     <p>Now that the partitions have been created, it's time to set up filesystems on
944     the boot and root partitions so that they can be mounted and used to store data.
945     We will also configure the swap partition to serve as swap storage.
946     </p>
947    
948     <p>Gentoo Linux supports a variety of different types of filesystems; each type has
949     its strengths and weaknesses and its own set of performance characteristics. Currently,
950     we support the creation of ext2, ext3, XFS, JFS and ReiserFS filesystems.</p>
951    
952     <p>ext2 is the tried and true Linux filesystem but doesn't have metadata
953     journaling, which means that routine ext2 filesystem checks at startup time can
954     be quite time-consuming. There is now quite a selection of newer-generation
955     <i>journaled</i> filesystems that can be checked for consistency very quickly
956     and are thus generally preferred over their non-journaled counterparts.
957     Journaled filesystems prevent long delays when you boot your system and your
958     filesystem happens to be in an <i>inconsistent</i> state.</p>
959    
960     <p>ext3 is the journaled version of the ext2 filesystem, providing metadata
961     journaling for fast recovery in addition to other enhanced journaling modes
962     like full data and ordered data journaling. ext3 is a very good and reliable
963 drobbins 1.88 filesystem. It offers generally decent performance under most conditions.
964     Because it does not extensively employ the use of "trees" in its internal
965     design, it doesn't scale very well, meaning that it is not an ideal choice for
966     very large filesystems, or situations where you will be handling very large
967     files or large quantities of files in a single directory. But when used within
968     its design parameters, ext3 is an excellent filesystem.</p>
969 drobbins 1.86
970     <p>ReiserFS is a B*-tree based filesystem that has very good overall
971     performance and greatly outperforms both ext2 and ext3 when dealing with small
972     files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales
973     extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is
974     now rock-solid and highly recommended for use both as a general-purpose
975     filesystem and for extreme cases such as the creation of large filesystems, the
976     use of many small files, very large files, and directories containing tens of
977     thousands of files. ReiserFS is the filesystem we recommend by default for all
978     non-boot partitions.</p>
979    
980     <p>XFS is a filesystem with metadata journaling that is fully supported under
981     Gentoo Linux's <path>xfs-sources</path> kernel. It comes with a robust
982     feature-set and is optimized for scalability. We only recommend using this
983     filesystem on Linux systems with high-end SCSI and/or fibre channel storage and
984     a uninterruptible power supply. Because XFS aggressively caches in-transit data
985     in RAM, improperly designed programs (those that don't take proper precautions
986     when writing files to disk, and there are quite a few of them) can lose a good
987     deal of data if the system goes down unexpectedly.</p>
988    
989 swift 1.142 <p>JFS is IBM's high-performance journaling filesystem. It has recently
990 drobbins 1.86 become production-ready, and there hasn't been a sufficient track record to
991 swift 1.142 comment positively nor negatively on its general stability at this
992 drobbins 1.86 point.</p>
993    
994     <p>If you're looking for the most rugged journaling filesystem, use ext3. If
995     you're looking for a good general-purpose high-performance filesystem with
996     journaling support, use ReiserFS; both ext3 and ReiserFS are mature,
997     refined and recommended for general use.</p>
998    
999     <!-- Corner case, confusing
1000 drobbins 1.70 <p>But before creating filesystems, you may want to initialize the
1001 jhhudso 1.81 beginning of your partition using <c>dd</c> if you are using a pre-existing partition that has been used before.
1002 drobbins 1.70 This is particularly helpful when you're going to create a new XFS filesystem on a partition that previously contained
1003     a ReiserFS filesystem. Doing this will ensure that your new filesystem
1004 seemant 1.78 will not be mis-identified by Linux's filesystem auto-detection code.
1005 drobbins 1.21 This can be done as follows:
1006 zhen 1.6 </p>
1007 jhhudso 1.81 <pre caption="Initializing first 1024 bytes of your partition">

1011     <warn>The command above will destroy all data from <path>/dev/hda3</path>.
1012 zhware 1.43 Be careful and check twice which partition you specify for zeroing.

1014     </warn>
1015 drobbins 1.86 -->
1016    
1017     <p>Based on our example above, we will use the following commands to initialize
1018     all our partitions for use:</p>
1019    
1020     <pre caption="Initializing our partitions (example)">
1021     # mke2fs -j /dev/hda1
1022     # mkswap /dev/hda2
1023     # mkreiserfs /dev/hda3
1024     </pre>
1025    
1026 drobbins 1.98 <p>We choose ext3 for our <c>/dev/hda1</c> boot partition because it is a
1027     robust journaling filesystem supported by all major boot loaders. We used
1028     <c>mkswap</c> for our <c>/dev/hda2 </c> swap partition -- the choice is obvious
1029     here. And for our main root filesystem on <c>/dev/hda3</c> we choose ReiserFS,
1030     since it is a solid journaling filesystem offering excellent performance. Now,
1031     go ahead and initialize your partitions.</p>
1032    
1033     <p>For your reference, here are the various <c>mkfs</c>-like commands available
1034     during the installation process:</p>
1035 drobbins 1.86
1036 drobbins 1.89 <p><c>mkswap</c> is the command that is used to initialize swap partitions:</p>

1039 jhhudso 1.81 </pre>
1040 drobbins 1.89 <p>You can use the <c>mke2fs</c> command to create ext2 filesystems:</p>
1041 jhhudso 1.81 <pre caption="Creating an ext2 Filesystem">
1042 drobbins 1.1 # <i>mke2fs /dev/hda1</i>
1043 jhhudso 1.81 </pre>
1044 drobbins 1.86 <p>If you would like to use ext3, you can create ext3 filesystems using
1045 drobbins 1.89 <c>mke2fs -j</c>:</p>
1046 drobbins 1.86 <pre caption="Creating an ext3 Filesystem">
1047     # <c>mke2fs -j /dev/hda3</c>

1050     <uri>http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html</uri>.</note>
1051 drobbins 1.89 <p>To create ReiserFS filesystems, use the <c>mkreiserfs</c> command:</p>
1052 drobbins 1.86 <pre caption="Creating a ReiserFS Filesystem">
1053     # <c>mkreiserfs /dev/hda3</c>
1054     </pre>
1055 drobbins 1.89 <p>To create an XFS filesystem, use the <c>mkfs.xfs</c> command:</p>
1056 jhhudso 1.81 <pre caption="Creating a XFS Filesystem">
1057 drobbins 1.1 # <c>mkfs.xfs /dev/hda3</c>
1058 jhhudso 1.81 </pre>
1059     <note>You may want to add a couple of additional flags to the
1060     <c>mkfs.xfs</c> command: <c>-d agcount=3 -l size=32m</c>.
1061     The <c>-d agcount=3</c> command will lower the number of allocation groups.
1062     XFS will insist on using at least 1 allocation group per 4 GB of your
1063     partition, so, for example, if you have a 20 GB partition you will need
1064     a minimum agcount of 5. The <c>-l size=32m</c> command increases the
1065     journal size to 32 Mb, increasing performance.</note>
1066 drobbins 1.86
1067 drobbins 1.89 <p>To create JFS filesystems, use the <c>mkfs.jfs</c> command:</p>

1085 jhhudso 1.75 <p>Next, we will create the <path>/mnt/gentoo</path> and <path>/mnt/gentoo/boot</path> mount points,
1086 zhen 1.93 and we will mount our filesystems to these mount points. Once our boot and root filesystems are
1087 drobbins 1.86 mounted, any files we copy or create inside <path>/mnt/gentoo</path> will be placed on our new filesystems.
1088     Note that if you are setting up Gentoo

1275 drobbins 1.86
1276     <p>Now that you have a working copy of the Portage tree, it is time to
1277     customize the optimization and optional build-time settings to use on your
1278     Gentoo Linux system. Portage will use these settings when compiling any
1279     programs for you. To do this, edit the file <path>/etc/make.conf</path>. In
1280     this file, you should set your <c>USE</c> flags, which specify optional
1281     functionality that you would like to be built into packages if available;
1282     generally, the defaults (an <e>empty</e> or unset <c>USE</c> variable) are
1283     fine. More information on <c>USE</c> flags can be found <uri
1284     link="http://www.gentoo.org/doc/en/use-howto.xml">here</uri>. A complete list
1285     of current USE flags can be found <uri
1286     link="http://www.gentoo.org/dyn/use-index.xml">here</uri>. </p>
1287    
1288 swift 1.142 <p>If you are starting from a stage1 tarball, You also should set appropriate <c>CHOST</c>, <c>CFLAGS</c> and
1289 drobbins 1.86 <c>CXXFLAGS</c> settings for the kind of system that you are creating
1290 swift 1.142 (commented examples can be found further down in the file). If you are using
1291     a stage2 or stage3 tarball, these settings will already be configured
1292     optimally and should not require any modification.</p>
1293    
1294     <impo><b>Advanced users:</b> The <c>CFLAGS</c> and <c>CXXFLAGS</c> settings
1295     settings
1296     are used to tell the C and C++ compiler how to optimize the code that
1297 drobbins 1.86 is generated on your system. It is common for users with Athlon XP processors
1298     to specify a "-march=athlon-xp" setting in their CFLAGS and CXXFLAGS settings
1299     so that all packages built will be optimized for the instruction set and
1300     performance characteristics of their CPU, for example. The <path>/etc/make.conf</path>
1301 swift 1.142 file contains a general guide for the proper settings of CFLAGS and CXXFLAGS.

1304     <!-- needs qa
1305     <note><b>Advanced users:</b>If you are building from a stage1 and don't want

1464 swift 1.142
1465     <p>There are two options for installing a kernel. You can either configure your own kernel or use the <c>genkernel</c>
1466     utility to configure and compile your kernel automatically.</p>
1467    
1468    
1469     <p>Whether configuring a kernel by hand or using <c>genkernel</c>,
1470     you'll need to merge the Linux kernel sources you'd like to use.
1471 swift 1.122 Gentoo provides several kernel ebuilds; a list can be found
1472     <uri link="/doc/en/gentoo-kernel.xml">here</uri>. If you are uncertain
1473 swift 1.142 which kernel sources to choose, we advise using <c>gentoo-sources</c>.
1474     <!--or <c>vanilla-sources</c>.(2.4.21-vanilla has sound issues)--> If you want XFS support, you should choose
1475     <c>xfs-sources</c> or <c>gs-sources</c>. Gentoo's LiveCD uses
1476     <c>gs-sources</c> and <c>xfs-sources</c>. There is also a
1477     <c>gaming-sources</c> kernel optimized for game-playing
1478     responsiveness that works wonderfully for this purpose when the
1479     "Preemptible kernel" option is enabled.
1480     </p>

1500     <title>Using genkernel to compile your kernel</title>
1501     <body>
1502    
1503     <p>Now that your kernel source tree is installed, it's now time to
1504     compile your kernel. There are two ways to do this. The first way is
1505     to use our new <c>genkernel</c> script to automatically build a kernel
1506     for you. <c>genkernel</c> works by configuring a kernel nearly
1507     identically to the way our LiveCD kernel is configured. This means
1508     that when you use <c>genkernel</c> to build your kernel, your system
1509     will generally detect all your hardware at boot-time, just like our Live
1510     CD does. Because genkernel doesn't require any manual kernel
1511     configuration, it is an ideal solution for those users who may not
1512     be comfortable compiling their own kernels.</p>
1513    
1514     <p>Now, let's see how to use genkernel. First, emerge the genkernel
1515     ebuild:</p>
1516    
1517     <pre caption="Emerging genkernel">
1518     # <c>emerge -k genkernel</c>
1519     </pre>
1520    
1521     <p>Now, compile your kernel sources by running <c>genkernel</c>:</p>
1522    
1523     <note><b>Advanced users:</b> you can type <c>genkernel --config</c> instead,
1524     which will cause genkernel to allow you to tweak the default kernel configuration before
1525     building begins.</note>

1560     <p>Once <c>genkernel</c> completes, a kernel, full set of modules and <i>initial root disk</i> (initrd) will
1561     be created. We will use the kernel and initrd when configuring a boot loader later in this document. The
1562     initrd will be started immediately after booting to perform hardware autodetection (just like on the Live CD)
1563     before your "real" system starts up.</p>
1564    
1565     <p>Now, let's perform one more step to get our system to be more like the Live CD -- let's emerge hotplug.
1566     While the initrd autodetects hardware that is needed to boot your system, hotplug autodetects everything else.
1567     To emerge and enable hotplug, type the following:</p>

1721     filesystems, iptables, and more), although the 2.2 kernel sources can be
1722 drobbins 1.21 patched with ReiserFS and devfs support.
1723     Gentoo linux boot scripts require either tmpfs or ramdisk support in the kernel, so
1724 zhen 1.6 2.2 kernel users need to make sure that ramdisk support is compiled in (ie, not a module).
1725     It is <comment>vital</comment> that a <e>gentoo=notmpfs</e> flag be added to the kernel

1857 jhhudso 1.75 a few important system files and install the boot loader.
1858 zhen 1.6 The first file we need to
1859     configure is <path>/etc/fstab</path>. Remember that you should use
1860     the <c>notail</c> option for your boot partition if you chose to create a ReiserFS filesystem on it.
1861     Remember to specify <c>ext2</c>, <c>ext3</c> or <c>reiserfs</c> filesystem types as appropriate.
1862     </p>
1863 zhen 1.16 <p>Use something like the <path>/etc/fstab</path> listed below, but of course be sure to replace &quot;BOOT&quot;,
1864     &quot;ROOT&quot; and &quot;SWAP&quot; with the actual block devices you are using (such as <c>hda1</c>, etc.)</p>

2025     <title>Notes</title>
2026     <body>
2027     <p> In the spirit of Gentoo, users now have more than one bootloader to choose from.
2028     Using our virtual package system, users are now able to choose between both GRUB and
2029 swift 1.142 LILO as their bootloaders.
2030 zhen 1.49 </p>
2031     <p> Please keep in mind that having both bootloaders installed is not necessary.
2032 jhhudso 1.75 In fact, it can be a hindrance, so please only choose one.
2033 zhen 1.49 </p>
2034 swift 1.142 <p>In addition, you will need to configure our bootloader differently depending upon
2035     whether you are using <c>genkernel</c> (with kernel and initrd) or a kernel you
2036     compiled by hand. Be sure to take note of the important differences.</p>
2037    
2038 drobbins 1.69 <impo>If you are installing Gentoo Linux on a system with an NVIDIA nForce or nForce2 chipset
2039     with an integrated GeForce graphics card, you should use LILO and avoid GRUB. With on-board
2040 drobbins 1.70 video enabled, the low memory area of your RAM may be used as video RAM. Since GRUB also uses low
2041     memory at boot time, it may experience an "out of memory" condition. So, if you have an nForce
2042 drobbins 1.69 or potentially other board with on-board video, use LILO. Even if you're using off-board video
2043 jhhudso 1.75 right now, it would be nice to be able to remove the graphics card and use the on-board video in a
2044 drobbins 1.69 pinch, wouldn't it? :)</impo>

2047 zhen 1.16 <section>
2048 zhen 1.49 <title>Configuring GRUB</title>
2049 zhen 1.16 <body>
2050     <p>The most critical part of understanding GRUB is getting comfortable with how GRUB
2051 zhen 1.6 refers to hard drives and partitions. Your Linux partition <path>/dev/hda1</path> is called
2052     <path>(hd0,0)</path> under GRUB. Notice the parenthesis around the hd0,0 - they are required.
2053 zhen 1.16 Hard drives count from zero rather than &quot;a&quot;, and partitions start at zero rather than one.
2054 swift 1.142 Be aware too that with the hd devices, only hard drives are counted, not atapi-ide devices such as
2055 zhen 1.6 cdrom players, burners, and that the same construct can be used with scsi drives.
2056     (Normally they get higher numbers than ide drives except when the bios is configured
2057 swift 1.142 to boot from scsi devices.) Assuming you have a hard drive on /dev/hda, a cdrom player on /dev/hdb,
2058     a burner on /dev/hdc, a second hard drive on /dev/hdd and no SCSI hard drive,
2059 zhen 1.6 <path>/dev/hdd7</path> gets translated to <path>(hd1,6)</path>.
2060    
2061 swift 1.142 It might sound tricky, and tricky it is indeed, but as we will see, GRUB
2062 zhen 1.6 offers a tab completion mechanism that comes handy for those of you having
2063 swift 1.142 a lot of hard drives and partitions and who are a little lost in the
2064     GRUB numbering scheme. Having gotten the feel for that,
2065 jhhudso 1.75 it is time to install GRUB.
2066 zhen 1.6 </p>
2067 zhen 1.16 <p>The easiest way to install GRUB is to simply type <c>grub</c> at your chrooted shell prompt: </p>
2068 jhhudso 1.81 <pre caption="Installing GRUB">
2069 swift 1.142 # <c>emerge -k grub</c>
2070 drobbins 1.1 # <c>grub</c>
2071 jhhudso 1.81 </pre>
2072 jhhudso 1.75 <p>You will be presented with the <c>grub&gt;</c> grub
2073 zhen 1.6 command-line prompt. Now, you need to type in the
2074     right commands to install the GRUB boot record onto your hard drive. In my example configuration,
2075     I want to install the GRUB boot record on my hard drive's MBR (master boot record), so that
2076     the first thing I see when I turn on the computer is the GRUB prompt. In my case, the commands
2077     I want to type are:
2078     </p>
2079 zhen 1.68
2080 jhhudso 1.81 <pre caption="GRUB on the MBR">
2081 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
2082     grub&gt; <c>setup (hd0)</c> <codenote>Where the boot record is installed, here, it is the MBR</codenote>
2083 jhhudso 1.81 </pre>
2084 zhen 1.68
2085 jhhudso 1.81 <pre caption="GRUB not on the MBR">
2086 zhen 1.53 <comment>Alternatively, if you wanted to install the bootloader somewhere other than the MBR</comment>
2087 zhen 1.68 grub&gt; <c>root (hd0,0)</c> <codenote>Your boot partition</codenote>
2088     grub&gt; <c>setup (hd0,4)</c> <codenote>Where the boot record is installed, here it is /dev/hda5</codenote>
2089 drobbins 1.1 grub&gt; <c>quit</c>
2090 jhhudso 1.81 </pre>
2091 swift 1.136
2092 jhhudso 1.75 <p>Here is how the two commands work. The first <c>root ( )</c> command tells GRUB
2093 zhen 1.6 the location of your boot partition (in our example, <path>/dev/hda1</path> or
2094     <path>(hd0,0)</path> in GRUB terminology. Then, the second <c>setup ( )
2095     </c> command tells GRUB where to install the
2096     boot record - it will be configured to look for its special files at the <c>root
2097     ( )</c> location that you specified. In my case, I want the boot record on the
2098     MBR of the hard drive, so I simply specify <path>/dev/hda</path> (also known as <path>(hd0)</path>).
2099     If I were using another boot loader and wanted to set up GRUB as a secondary boot-loader, I
2100     could install GRUB to the boot record of a particular partition. In that case,
2101 jhhudso 1.75 I would specify a particular partition rather than the entire disk. Once the GRUB
2102 zhen 1.6 boot record has been successfully installed, you can type <c>quit</c> to quit GRUB.
2103 zhen 1.52 </p>
2104 zhen 1.6
2105 swift 1.142 <note> The tab completion mechanism of GRUB can be used from within GRUB,
2106 zhen 1.6 assuming you wrote <c> root (</c> and that you hit the TAB key, you would
2107 swift 1.142 be prompted with a list of the available devices (not only hard drives),
2108     hitting the TAB key having written <c> root (hd</c>, GRUB would print the
2109     available hard drives and hitting the TAB key after writing <c> root (hd0,</c>
2110     would make GRUB print the list of partitions on the first hard drive.
2111 zhen 1.6
2112 swift 1.142 Checking the syntax of the GRUB location with completion should really help
2113 zhen 1.6 to make the right choice.
2114     </note>
2115    
2116 zhen 1.52 <p>
2117 zhen 1.6 Gentoo Linux is now
2118     installed, but we need to create the <path>/boot/grub/grub.conf</path> file so that
2119 jhhudso 1.75 we get a nice GRUB boot menu when the system reboots. Here is how to do it.
2120 zhen 1.6 </p>
2121 zhen 1.16 <impo>To ensure backwards compatibility with GRUB, make sure to make a link from

2150 zhen 1.16 <impo>
2151 swift 1.142 If you set up SCSI emulation for an IDE cd burner earlier, then to get it to
2152 zhen 1.16 actually work you need to add an &quot;hdx=ide-scsi&quot; fragment to the kernel
2153     line in grub.conf (where &quot;hdx&quot; should be the device for your cd burner).
2154 zhen 1.6 </impo>
2155 zhen 1.16 <p>After saving this file, Gentoo Linux installation is complete. Selecting the first option will
2156 zhen 1.6 tell GRUB to boot Gentoo Linux without a fuss. The second part of the grub.conf file is optional,
2157     and shows you how to use GRUB to boot a bootable Windows partition.
2158     </p>
2159 zhen 1.16 <note>Above, <path>(hd0,0)</path> should point to your &quot;boot&quot; partition
2160 zhen 1.6 (<path>/dev/hda1</path> in our example config) and <path>/dev/hda3</path> should point to
2161     your root filesystem. <path>(hd0,5)</path> contains the NT boot
2162     loader.
2163 zhware 1.9 </note>
2164 zhen 1.16 <note>
2165 zhware 1.9 The path to the kernel image is relative to the boot partition. If for example you have separated boot partition <path>(hd0,0)</path> and root partition <path>(hd0,1)</path>, all paths in the grub.conf file above will become <path>/bzImage</path>.
2166 zhen 1.6 </note>
2167 zhen 1.16 <p>If you need to pass any additional options to the kernel, simply
2168 zhen 1.6 add them to the end of the <c>kernel</c> command. We're already passing one option
2169     (<c>root=/dev/hda3</c>), but you can pass others as well. In particular, you can
2170     turn off devfs by default (not recommended unless you know what you're doing) by
2171     adding the <c>gentoo=nodevfs</c> option to the <c>kernel</c> command.
2172     </p>
2173 zhen 1.16 <note>Unlike in earlier versions of Gentoo Linux, you no longer have to add
2174 swift 1.142 <c>devfs=mount</c> to the end of the <c>kernel</c> line to enable devfs.

2221 zhen 1.16 <li><i>boot=/dev/hda</i> tells LILO to install itself on the first hard disk on the first IDE controller. </li>
2222     <li><i>map=/boot/map</i> states the map file. In normal use, this should not be modified. </li>
2223     <li><i>install=/boot/boot.b</i> tells LILO to install the specified file as the new boot sector.
2224     In normal use, this should not be altered. If the install line is missing, LILO will
2225     assume a default of /boot/boot.b as the file to be used. </li>
2226 zhen 1.83 <li>The existence of <i>prompt</i> tells LILO to display the classic <i>lilo:</i> prompt at bootup.

2230     with booting the default line entry. This is measured in tenths of a second, with 50 as the default. </li>
2231     <li><i>lba32</i> describes the hard disk geometry to LILO. Another common entry here is linear. You should

2285 drobbins 1.21 <p>It is always a good idea to make a boot disk the first
2286 zhen 1.16 time you install any Linux distribution. This is a security
2287 swift 1.136 blanket, and generally not a bad thing to do. If your hardware doesn't
2288     let you install a working bootloader from the chrooted environment,
2289     you may <e>need</e> to make a GRUB boot disk.
2290     If you are in this camp, make a GRUB boot disk, and when you reboot
2291     the first time you can install GRUB to the MBR. Make your bootdisks
2292     like this:

2322     <section>
2323     <body>
2324    
2325     <p>GRP users can, at this point, install binary packages:</p>
2326    
2327     <pre caption="Installing from GRP">
2328     # <c>USE="bindist" emerge -k xfree</c>
2329     <codenote>USE="bindist" must be set while installing GRP packages that use XFree86.</codenote>
2330     </pre>
2331    
2332     <p>CD 1 contains enough applications to install a working system with XFree86.
2333     Additionally, CD2 of the 2-CD GRP set contains other applications including KDE, GNOME, Mozilla, and others.
2334     To install these packages, you will need to reboot into your new Gentoo
2335     system first (covered in the "Installation complete!" section near the end of this document.) After you are running your basic Gentoo system from the hard
2336     drive, you can mount the second CD and copy files:</p>
2337    
2338     <pre caption="Loading binary packages from CD2">
2339     # <c>mount /dev/cdrom /mnt/cdrom</c>
2340     # <c>cp -a /mnt/cdrom/packages/* /usr/portage/packages/</c>
2341     </pre>
2342    
2343     <p>Now various other applications can be installed the same way. For example:</p>

2356 swift 1.142 <p>Now, Gentoo Linux is installed. The only remaining step is to update necessary configuration files, exit the chrooted shell,
2357 jhhudso 1.75
2358 zhen 1.6 safely unmount your partitions
2359     and reboot the system:

2366     files that don't have such a big impact, remove the updates of the

2402     <title>Gentoo-Stats</title>
2403     <section>
2404     <body>
2405     <p>The Gentoo Linux usage statistics program was started as an attempt to give the developers
2406 zhen 1.6 a way to find out about their user base. It collects information about Gentoo Linux usage to help
2407     us in set priorities our development. Installing it is completely optional, and it would be greatly
2408     appreciated if you decide to use it. Compiled statistics can be viewed at <uri>http://stats.gentoo.org/</uri>.
2409     </p>
2410 zhen 1.16 <p>The gentoo-stats server will assign a unique ID to your system.
2411 zhen 1.6 This ID is used to make sure that each system is counted only once. The ID will not be used
2412 peesh 1.99 to individually identify your system, nor will it be matched against an IP address or
2413 zhen 1.6 other personal information. Every precaution has been taken to assure your privacy in the
2414     development of this system. The following are the things that we are monitoring
2415 zhen 1.16 right now through our &quot;gentoo-stats&quot; program:
2416 zhen 1.6 </p>
2417 zhen 1.16 <ul>
2418     <li>installed packages and their version numbers</li>
2419     <li>CPU information: speed (MHz), vendor name, model name, CPU flags (like &quot;mmx&quot; or &quot;3dnow&quot;)</li>
2420     <li>memory information (total available physical RAM, total available swap space)</li>
2421     <li>PCI cards and network controller chips</li>
2422     <li>the Gentoo Linux profile your machine is using (that is, where the /etc/make.profile link is pointing to).</li>
2423     </ul>
2424     <p>We are aware that disclosure of sensitive information is a threat to most Gentoo Linux users
2425 zhen 1.6 (just as it is to the developers).
2426     </p>
2427 zhen 1.16 <ul>
2428     <li>Unless you modify the gentoo-stats program, it will never transmit sensitive
2429 zhen 1.6 information such as your passwords, configuration data, shoe size...</li>
2430 zhen 1.16 <li>Transmission of your e-mail addresses is optional and turned off by default.</li>
2431     <li>The IP address your data transmission originates from will never be logged
2432     in such a way that we can identify you. There are no &quot;IP address/system ID&quot; pairs.</li>
2433     </ul>
2434     <p>The installation is easy - just run the following commands:
2435 zhen 1.6 </p>
2436 jhhudso 1.81 <pre caption="Installing gentoo-stats">
2437 drobbins 1.1 # <c>emerge gentoo-stats</c> <codenote>Installs gentoo-stats</codenote>
2438     # <c>gentoo-stats --new</c> <codenote>Obtains a new system ID</codenote>
2439 jhhudso 1.81 </pre>
2440 zhen 1.16 <p>The second command above will request a new system ID and enter it into
2441 zhen 1.6 <path>/etc/gentoo-stats/gentoo-stats.conf</path> automatically. You can view this file
2442     to see additional configuration options.
2443     </p>
2444 zhen 1.16 <p>After that, the program should be run on a regular schedule
2445 zhen 1.6 (gentoo-stats does not have to be run as root). Add this line to your <path>crontab</path>:
2446     </p>
2447 jhhudso 1.81 <pre caption="Updating gentoo-stats with cron">
2448     <c>0 0 * * 0,4 /usr/sbin/gentoo-stats --update &gt; /dev/null</c>
2449     </pre>
2450 zhen 1.16 <p>The <c>gentoo-stats</c> program is a simple perl script which can be
