67<title>The Gentoo Installation Approaches</title>
68<subsection>
69<title>Introduction</title>
70<body>
71
72<p>
73Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
74A stage file is a tarball (compressed archive) that contains a minimal
75environment.
76</p>
77
78<ul>
79 <li>
80 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
81 software management system) and a couple of packages on which the compiler
82 or Portage depends.
83 </li>
84 <li>
85 A stage2 file contains a so-called bootstrapped system, a minimal
86 environment from which one can start building all other necessary
87 applications that make a Gentoo environment complete.
88 </li>
89 <li>
90 A stage3 file contains a prebuilt minimal system which is almost fully
91 deployable. It only lacks a few applications where you, the Gentoo user,
92 needs to choose which one you want to install.
93 </li>
94</ul>
95
96<p>
97To help you decide what stage file you want to use, we have written down the
98major advantages and disadvantages of each stage file.

104<title>A Stage1 Approach</title>
105<body>
106
107<p>
108A <e>stage1</e> is used when you want to bootstrap and build the entire system
109from scratch.
110</p>
111
112<p>
113This approach builds core system packages that are vital to your system and is
114used by Gentoo developers to prepare the Gentoo release media. It is a great
115installation method for those who would like to learn more about the inner
116workings of bootstrapping, toolchains and the like.
117</p>
118
119<p>
120However, if you do not plan to tweak the bootstrapping instructions in the
121<path>bootstrap.sh</path> script written by the Gentoo developers, then a
122stage1 approach has no benefits for you.

164<title>A Stage2 Approach</title>
165<body>
166
167<p>
168A <e>stage2</e> is used for building the entire system from a bootstrapped
169"semi-compiled" state.
170</p>
171
172<p>
173When you perform a stage2 installation approach, you will build all system
174packages (core packages, including toolchain) using your specific <c>USE</c>,
175<c>CFLAGS</c> and <c>CXXFLAGS</c> settings. Any package build will therefore be
176optimized to your preference.
177</p>
178
179<p>
180However, this installation takes some time and if you do not intend to change
181the <c>CFLAGS</c> and <c>CXXFLAGS</c> settings that we have defined as a "good
182default", using this approach only makes sense if your <c>USE</c> variable is
183sufficiently different from the default <c>USE</c> we provide.

218<title>A Stage3 Approach</title>
219<body>
220
221<p>
222A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
223built for you. You will only need to build a few packages (such as system
224logger, networking tools, ...) before you can boot into a base Gentoo
225installation.
226</p>
227
228<p>
229Choosing to go with a stage3 allows for the fastest install of Gentoo
230Linux, but also means that your base system will have the optimization
231settings that we chose for you (which to be honest, are good settings
232and were carefully chosen to enhance performance while maintaining
233stability). Stage3 is also required if you want to install Gentoo using
234prebuilt packages or without a network connection.
235</p>
236

249 You can still tweak your system

251</tr>
252</table>
253
254<p>
255You might be interested to know that, if you decide to use different
256optimization settings after having installed Gentoo, you will be able to
257recompile your entire system with the new optimization settings. The same goes
258for any <c>USE</c> flag changes: Portage is intelligent enough to know what
259packages need to be rebuild.

184A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
185to continue the Gentoo installation using the instructions in this manual.
186Previously, the Gentoo Handbook described the installation using one of three
187stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
188official installation method uses the stage3 tarball. If you are interested in
189performing a Gentoo installation using a stage1 or stage2 tarball, please read
190the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo

197<title>Choosing a userland</title>
198<body>
199
200<p>
201On PPC64, the kernel is 64-bit and the <e>userland</e> can be 32-bit or 64-bit. The
202userland is basically the applications you are running, such as
203<c>bash</c> or <c>mozilla-firefox</c>. They can be compiled and run in either
20464-bit or 32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit
205userlands, so which one should you use?
206</p>
207
208<p>
209You may have heard that 64-bit applications are better, but in fact, 32-bit
210applications take up slightly less memory and often run a little bit faster than
21164-bit applications.
212</p>
213
214<p>
215You really only need 64-bit applications when you need more memory than a 32-bit
216userland allows, or if you do a lot of 64-bit number crunching. If you run
217applications that require more than 4GB of memory or you run scientific
218applications, you should choose the 64-bit userland. Otherwise, choose the
21932-bit userland, as it is recommended by the Gentoo/PPC64 developers.
220</p>
221
222<p>
223Additionally, the 32-bit userland has been available in Portage longer than the
22464-bit userland has. This means that there are more applications tested in the
22532-bit userland that just work "out of the box." Many applications compiled for
226the 64-bit userland may be just as stable as the 32-bit version, but they
227haven't been tested yet. Though testing isn't difficult to do, it can be
228annoying and time consuming if you want to use many untested 64-bit
229applications. Also, some programs just won't run in the 64-bit userland until
230their code is fixed, such as OpenOffice.
231</p>
232
233<p>
234The Gentoo/PPC64 team provides stages and Package CDs for both 32-bit and 64-bit
235userlands, so no matter which one you choose, you'll be able to successfully
236install Gentoo and get a full system up and running with minimal fuss.

558When the Installation CD boots, it tries to detect all your hardware devices and
559loads the appropriate kernel modules to support your hardware. In the
560vast majority of cases, it does a very good job. However, in some cases it may
561not auto-load the kernel
562modules you need. If the PCI auto-detection missed some of your system's
563hardware, you will have to load the appropriate kernel modules manually.
564</p>
565
566<p>
567In the next example we try to load the <c>8139too</c> module (support for
568certain kinds of network interfaces):

578<title>Optional: Tweaking Hard Disk Performance</title>
579<body>
580 487
581<p>
582If you are an advanced user, you might want to tweak the IDE hard disk
583performance using <c>hdparm</c>. With the <c>-tT</c> options you can
584test the performance of your disk (execute it several times to get a
585more precise impression):
586</p>
587
588<pre caption="Testing disk performance">
589# <i>hdparm -tT /dev/hda</i>
590</pre>
591
592<p>
593To tweak, you can use any of the following examples (or experiment
594yourself) which use <path>/dev/hda</path> as disk (substitute with your
595disk):
596</p>
597
598<pre caption="Tweaking hard disk performance">

606<title>Optional: User Accounts</title>
607<body>
608
609<p>
610If you plan on giving other people access to your installation
611environment or you want to chat using <c>irssi</c> without root privileges (for
612security reasons), you need to create the necessary user accounts and change
613the root password.
614</p>
615
616<p>
617To change the root password, use the <c>passwd</c> utility:
618</p>
619
620<pre caption="Changing the root password">
621# <i>passwd</i>
622New password: <comment>(Enter your new password)</comment>
623Re-enter password: <comment>(Re-enter your password)</comment>
624</pre>
625
626<p>
627To create a user account, we first enter their credentials, followed by
628its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
629In the next example, we create a user called &quot;john&quot;.
630</p>
631
632<pre caption="Creating a user account">
633# <i>useradd -m -G users john</i>
634# <i>passwd john</i>
635New password: <comment>(Enter john's password)</comment>
636Re-enter password: <comment>(Re-enter john's password)</comment>
637</pre>
638
639<p>
640You can change your user id from root to the newly created user by using
641<c>su</c>:

654<p>
655If you want to view the Gentoo Handbook during the installation, make sure you
656have created a user account (see <uri link="#useraccounts">Optional: User
657Accounts</uri>). Then press <c>Alt-F2</c> to go to a new terminal and log in.
658</p>
659
660<p>
661If you want to view the documentation on the CD you can immediately run
662<c>links2</c> to read it:
663</p>
664
665<pre caption="Viewing the on-CD documentation">
666# <i>links2 /mnt/cdrom/docs/handbook/html/index.html</i>
667</pre>
668
669<p>
670However, it is preferred that you use the online Gentoo Handbook as it will be
671more recent than the one provided on the CD.
672</p>
673
674<pre caption="Viewing the Online Documentation">

685<title>Optional: Starting the SSH Daemon</title>
686<body>
687
688<p>
689If you want to allow other users to access your computer during the
690Gentoo installation (perhaps because those users are going to help you
691install Gentoo, or even do it for you), you need to create a user
692account for them and perhaps even provide them with your root password
693(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
694</p>
695
696<p>
697To fire up the SSH daemon, execute the following command:
698</p>
699
700<pre caption="Starting the SSH daemon">
701# <i>/etc/init.d/sshd start</i>
702</pre>
703
704<p>
705To be able to use sshd, you first need to set up your networking. Continue with
706the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
