57Still interested in trying out Gentoo? Well, then it is now time to
58choose the installation medium you want to use. Yes, you have the
59choice, no, they are not all equal, and yes, the result is always the same: a
60Gentoo base system.
61</p>
62
63<p>
64The installation media we will describe are:
65</p>
66
67<ul>
68<li>Gentoo's Minimal LiveCD</li>
69<li>Gentoo's Universal LiveCD</li>
70</ul>
71
72<p>
73Every single media has its advantages and disadvantages. We will list
74the pros and cons of every medium so you have all the information to
75make a justified decision. But before we continue, let's explain our
76three-stage installation.

82<title>The Three Stages</title>
83<body>
84
85<p>
86Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
87The one you choose depends on how much of the system you want to compile
88yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
89build the entire system from scratch. The <e>stage2</e> tarball is used for
90building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
91The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
92been built for you. As we will explain later, you can also install
93Gentoo without compiling anything (except your kernel and some optional
94packages). If you want this, you have to use a <e>stage3</e> tarball.
95</p>
96
97<p>
98Now what stage do you have to choose?
99</p>
100
101<p>
102Starting from a <e>stage1</e> allows you to have total control over the
103optimization settings and optional build-time functionality that is
104initially enabled on your system. This makes <e>stage1</e> installs good for
105power users who know what they are doing. It is also a great
106installation method for those who would like to know more about the
107inner workings of Gentoo Linux.
108</p>
109
110<p>
111A <e>stage1</e> installation can only be performed when you have a working
112Internet connection.

154<e>Stage2</e> installs allow you to skip the bootstrap process and doing this
155is fine if you are happy with the optimization settings that we chose
156for your particular <e>stage2</e> tarball.
157</p>

202Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
203Linux, but also means that your base system will have the optimization
204settings that we chose for you (which to be honest, are good settings
205and were carefully chosen to enhance performance while maintaining
206stability). <e>stage3</e> is also required if you want to install Gentoo using
207prebuilt packages or without a network connection.

234Write down (or remember) what stage you want to use. You need this later when
235you decide what LiveCD (or other installation medium) you want to use. You might
236be interested to know that, if you decide to use different optimization settings
237after having installed Gentoo, you will be able to recompile your entire system
238with the new optimization settings.

320Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
321networking. It contains a stage1 and stage3 tarballs (optimized for the
322sparc architecture). For example the sparc64 variant of this CD is called

324<path>sparc64/</path> subdirectory.

332need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
333etc. without having to compile every single one of them, you need the Packages
334CD too. Such a Packages CD for sparc64 is called

204Previously, the Gentoo Handbook described the installation using one of three

206official installation method uses the stage3 tarball. If you are interested in

514<title>Optional: Tweaking Hard Disk Performance</title>
515<body>
516 331
517<p>
518If you are an advanced user, you might want to tweak the IDE hard disk
519performance using <c>hdparm</c>. With the <c>-tT</c> options you can
520test the performance of your disk (execute it several times to get a
521more precise impression):
522</p>
523
524<pre caption="Testing disk performance">
525# <i>hdparm -tT /dev/hda</i>
526</pre>
527
528<p>
529To tweak, you can use any of the following examples (or experiment
530yourself) which use <path>/dev/hda</path> as disk (substitute with your
531disk):
532</p>
533
534<pre caption="Tweaking hard disk performance">

542<title>Optional: User Accounts</title>
543<body>
544
545<p>
546If you plan on giving other people access to your installation
547environment or you want to chat using <c>irssi</c> without root privileges (for
548security reasons), you need to create the necessary user accounts and change
549the root password.
550</p>
551
552<p>
553To change the root password, use the <c>passwd</c> utility:
554</p>
555
556<pre caption="Changing the root password">
557# <i>passwd</i>
558New password: <comment>(Enter your new password)</comment>
559Re-enter password: <comment>(Re-enter your password)</comment>
560</pre>
561
562<p>
563To create a user account, we first enter their credentials, followed by
564its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
565In the next example, we create a user called &quot;john&quot;.
566</p>
567
568<pre caption="Creating a user account">
569# <i>useradd john</i>
570# <i>passwd john</i>

572Re-enter password: <comment>(Re-enter john's password)</comment>
573</pre>
574
575<p>
576You can change your user id from root to the newly created user by using
577<c>su</c>:

590<p>
591If you want to allow other users to access your computer during the
592Gentoo installation (perhaps because those users are going to help you
593install Gentoo, or even do it for you), you need to create a user
594account for them and perhaps even provide them with your root password
595(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
596</p>
597
598<p>
599To fire up the SSH daemon, execute the following command:
600</p>
601
602<pre caption="Starting the SSH daemon">
603# <i>/etc/init.d/sshd start</i>
604</pre>
605

607To be able to use sshd, you first need to setup your networking. Continue with
