59<title>The Gentoo Installation Approaches</title>
60<subsection>
61<title>Introduction</title>

64<p>
65Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
66A stage file is a tarball (compressed archive) that contains a minimal
67environment.
68</p>
69
70<ul>
71 <li>
72 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
73 software management system) and a couple of packages on which the compiler
74 or Portage depends.
75 </li>
76 <li>
77 A stage2 file contains a so-called bootstrapped system, a minimal
78 environment from which one can start building all other necessary
79 applications that make a Gentoo environment complete.
80 </li>
81 <li>
82 A stage3 file contains a prebuilt minimal system which is almost fully
83 deployable. It only lacks a few applications where you, the Gentoo user,
84 needs to choose which one you want to install.
85 </li>
86</ul>
87
88<p>
89To help you decide what stage file you want to use, we have written down the
90major advantages and disadvantages of each stage file.

96<title>A Stage1 Approach</title>
97<body>
98
99<p>
100A <e>stage1</e> is used when you want to bootstrap and build the entire system
101from scratch.
102</p>
103
104<p>
105Starting from a stage1 allows you to have total control over the
106optimization settings and optional build-time functionality that is
107initially enabled on your system. This makes <e>stage1</e> installs good for
108power users who know what they are doing. It is also a great
109installation method for those who would like to know more about the
110inner workings of Gentoo Linux.

158A <e>stage2</e> is used for building the entire system from a bootstrapped
159"semi-compiled" state.
160</p>
161
162<p>
163Stage2 installs allow you to skip the bootstrap process; doing this
164is fine if you are happy with the optimization settings that we chose
165for your particular stage2 tarball.

208<title>A Stage3 Approach</title>
209<body>
210
211<p>
212A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
213built for you. You will only need to build a few packages of which we can't
214decide for you which one to choose.
215</p>
216
217<p>
218Choosing to go with a stage3 allows for the fastest install of Gentoo
219Linux, but also means that your base system will have the optimization
220settings that we chose for you (which to be honest, are good settings
221and were carefully chosen to enhance performance while maintaining
222stability). Stage3 is also required if you want to install Gentoo using
223prebuilt packages or without a network connection.

240
241<p>
242You might be interested to know that, if you decide to use different
243optimization settings after having installed Gentoo, you will be able to
244recompile your entire system with the new optimization settings.

202Previously, the Gentoo Handbook described the installation using one of three
203stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
204official installation method uses the stage3 tarball. If you are interested in
205performing a Gentoo installation using a stage1 or stage2 tarball, please read
