37This guide contains all commands you should use to complete a stage3
38installation of Gentoo. You need a connection to the Internet to download the
39stage3 and Portage snapshots.

43Timing output follows all commands that take more than a couple of seconds to
44finish. Commands were timed on an AMD 2000 1.66 Ghz PC with 512 Mb of RAM and
45two SATA disks connected to a hardware controller.

47 100option to prevent the X graphical environment from starting. Several options
101allow to enable or disable some features. If all goes well, your hardware will
102be detected and all modules will be loaded. If the kernel fails to boot
103properly or if your computer hangs during the boot procedure, you may have to
104experience with different configurations. The safest way is probably to use the
105<c>nodetect</c> option and then load required modules explicitely.

168Alternatively, you can start networking manually. The following example assigns
169the IP addess 192.168.1.10 to your PC and defines 192.168.1.1 as your router

208Now, set the root password on the liveCD so that you can connect to it from
209another PC. Please note that allowing root to connect over ssh is not
210recommended under normal circumstances. If you can't trust your local network,
211use a long and complex password, you should use it only once as it will
212disappear after your first rebot.

756If you enabled the <c>userlocales</c> USE flag for versions of glibc that still
757support it, you should edit <path>/etc/locales.build</path> and define the
758locales you want to build.
759</p>
760
761<p>
762Later versions of glibc ignore the userlocales USE flag and use
763<path>/etc/locale.gen</path> instead. If you are upgrading glibc to such a
764version, you should create <path>/etc/locale.gen</path> <e>and remove</e>
765<path>/etc/locales.build</path>. Check the output of <c>emerge -vpe world</c>
766to know whether glibc supports the userlocales USE flag.

781Last but not least, you may want to alter the <c>CFLAGS</c> variable in your
782<path>/etc/make.conf</path> to optimise the code to your specific needs. Please
783note that using a long list of flags is rarely needed and can even lead to a
784broken system. It is recommended to specify the processor type in the
785<c>march</c> option and stick to <c>-O2 -pipe</c>.
786</p>
787
788<p>
789You may also want to switch to <b>~x86</b>. You should only do this if you can
790deal with the odd broken ebuild or package. If you'd rather keep your system
791stable, don't add the <c>ACCEPT_KEYWORDS</c> variable. Adding
792<c>FEATURES="parallel-fetch ccache"</c> is also a good idea.
793</p>
794
795<note>
796At the time of writing, the ~x86 version of <c>portage</c> is significantly
797faster when updating its cache. Even if you stick to the x86 keyword, you might
798want to use the ~x86 version of Portage. Check the <uri
799link="/doc/en/handbook/handbook-x86.xml?part=3&amp;chap=3#doc_chap2">Mixing
800Stable with Testing</uri> chapter if you forgot how to do this.

813<p>
814You might want to recompile your whole system twice to make full use of your
815latest configuration changes. It would take quite a long time to complete and
816yield minimal speed benefits. It is recommended that you let your system
817optimise itself gradually over time when new versions of packages are
818released.
819</p>
820
821<p>
822Recompiling only the packages that have already been updated since the release
823or that are affected by your new USE flags will take enough time. You might
824also have to remove packages that block your upgrade. Look for "[blocks
825<brite>B</brite> ]" in the output of <c>emerge -vpuD --newuse world</c> and
826use <c>emerge -C</c> to remove them.

868Depending on what your new Gentoo machine is supposed to do, you will probably
869want to install server applications or a desktop system. Just as an example,
870<c>emerge gnome</c> and <c>emerge kde</c> have been timed on the ~x86 system
871installed as describe above. Both have been installed from the same starting
872point.

876You should check our <uri link="/doc/en/">documentation index</uri> to find out
877how to install and configure the applications of your choice.
