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
205stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
206official installation method uses the stage3 tarball. If you are interested in

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

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

570Re-enter password: <comment>(Re-enter john's password)</comment>
571</pre>
572
573<p>
574You can change your user id from root to the newly created user by using
575<c>su</c>:

586<body>
587
588<p>
589If you want to view the Gentoo Handbook (either from-CD or online) during the
590installation, make sure you have created a user account (see <uri
591link="#useraccouts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
592go to a new terminal and log in.
593</p>
594
595<p>
596If you want to view the documentation on the CD you can immediately run
597<c>links2</c> to read it:

601# <i>links2 /mnt/cdrom/docs/html/index.html</i>
602</pre>
603

605However, it is preferred that you use the online Gentoo Handbook as it will be
606more recent than the one provided on the CD. You can view it using <c>links2</c>
607as well, but only after having completed the <e>Configuring your Network</e>
608chapter (otherwise you won't be able to go on the Internet to view the
609document):

624<body>
625
626<p>
627If you want to allow other users to access your computer during the
628Gentoo installation (perhaps because those users are going to help you
629install Gentoo, or even do it for you), you need to create a user
630account for them and perhaps even provide them with your root password
631(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
632</p>
633
634<p>
635To fire up the SSH daemon, execute the following command:
636</p>
637
638<pre caption="Starting the SSH daemon">
639# <i>/etc/init.d/sshd start</i>

643To be able to use sshd, you first need to setup your networking. Continue with
644the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
