70<title>The Gentoo Installation Approaches</title>
71<subsection>
72<title>Introduction</title>
73<body>
74
75<p>
76Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
77A stage file is a tarball (compressed archive) that contains a minimal
78environment.
79</p>
80
81<ul>
82 <li>
83 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
84 software management system) and a couple of packages on which the compiler
85 or Portage depends.
86 </li>
87 <li>
88 A stage2 file contains a so-called bootstrapped system, a minimal
89 environment from which one can start building all other necessary
90 applications that make a Gentoo environment complete.
91 </li>
92 <li>
93 A stage3 file contains a prebuilt minimal system which is almost fully
94 deployable. It only lacks a few applications where you, the Gentoo user,
95 needs to choose which one you want to install.
96 </li>
97</ul>
98
99<p>
100To help you decide what stage file you want to use, we have written down the
101major advantages and disadvantages of each stage file.

106<subsection>
107<title>A Stage1 Approach</title>
108<body>
109
110<p>
111A <e>stage1</e> is used when you want to bootstrap and build the entire system
112from scratch.
113</p>
114
115<p>
116Starting from a stage1 allows you to have total control over the
117optimization settings and optional build-time functionality that is
118initially enabled on your system. This makes <e>stage1</e> installs good for
119power users who know what they are doing. It is also a great
120installation method for those who would like to know more about the
121inner workings of Gentoo Linux.

166<body>
167
168<p>
169A <e>stage2</e> is used for building the entire system from a bootstrapped
170"semi-compiled" state.
171</p>
172
173<p>
174Stage2 installs allow you to skip the bootstrap process; doing this
175is fine if you are happy with the optimization settings that we chose
176for your particular stage2 tarball.

219<title>A Stage3 Approach</title>
220<body>
221
222<p>
223A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
224built for you. You will only need to build a few packages of which we can't
225decide for you which one to choose.
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>

247 <th>-</th>
248 <ti>You cannot tweak the base system - it's built already</ti>
249</tr>
250</table>
251
252<p>
253You might be interested to know that, if you decide to use different
254optimization settings after having installed Gentoo, you will be able to
255recompile your entire system with the new optimization settings.

650When the Installation CD boots, it tries to detect all your hardware devices and
651loads the appropriate kernel modules to support your hardware. In the
652vast majority of cases, it does a very good job. However, in some cases, it may
653not auto-load the kernel modules you need. If the PCI auto-detection missed some
654of your system's hardware, you will have to load the appropriate kernel modules
655manually.
