<title>The Gentoo Installation Approaches</title>
<subsection>
<title>Introduction</title>
<body>

<p>
Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
A stage file is a tarball (compressed archive) that contains a minimal
environment.
</p>

<ul>
  <li>
     A stage1 file contains nothing more than a compiler, Portage (Gentoo's
     software management system) and a couple of packages on which the compiler
     or Portage depends.
   </li>
   <li>
     A stage2 file contains a so-called bootstrapped system, a minimal
     environment from which one can start building all other necessary
     applications that make a Gentoo environment complete.
   </li>
   <li>
     A stage3 file contains a prebuilt minimal system which is almost fully
     deployable. It only lacks a few applications where you, the Gentoo user,
     needs to choose which one you want to install.
   </li>
</ul>

<p>
To help you decide what stage file you want to use, we have written down the
major advantages and disadvantages of each stage file.
</p>

</body>
</subsection>
<subsection>
<title>A Stage1 Approach</title>
<body>

<p>
A <e>stage1</e> is used when you want to bootstrap and build the entire system 
from scratch.
</p>

<p>
This approach builds core system packages that are vital to your system and is
used by Gentoo developers to prepare the Gentoo release media. It is a great
installation method for those who would like to learn more about the inner
workings of bootstrapping, toolchains and the like.
</p>

<p>
However, if you do not plan to tweak the bootstrapping instructions in the
<path>bootstrap.sh</path> script written by the Gentoo developers, then a 
stage1 approach has no benefits for you. 
</p>

<table>
<tr>
  <th>Stage1</th>
  <th>Pros and Cons</th>

  <ti>
    Allows you to have total control over the installation routine, bootstrap
    sequence, etc.

  </ti>
</tr>
<tr>
  <th>-</th>
  <ti>
    Requires a working Internet connection during the installation
  </ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>A Stage2 Approach</title>
<body>

<p>
A <e>stage2</e> is used for building the entire system from a bootstrapped
"semi-compiled" state.
</p>

<p>
When you perform a stage2 installation approach, you will build all system
packages (core packages, including toolchain) using your specific <c>USE</c>, 
<c>CFLAGS</c> and <c>CXXFLAGS</c> settings. Any package build will therefore be
optimized to your preference.
</p>

<p>
However, this installation takes some time and if you do not intend to change
the <c>CFLAGS</c> and <c>CXXFLAGS</c> settings that we have defined as a "good
default", using this approach only makes sense if your <c>USE</c> variable is
sufficiently different from the default <c>USE</c> we provide.
</p>

<table>
<tr>
  <th>Stage2</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>You don't need to bootstrap</ti>
</tr>
<tr>
  <th>+</th>
  <ti>Faster than starting with stage1</ti>
</tr>
<tr>
  <th>+</th>
  <ti>You can still tweak your settings</ti>
</tr>
<tr>
  <th>-</th>
  <ti>It's still not the fastest way to install Gentoo</ti>
</tr>
<tr>
  <th>-</th>
  <ti>
    Requires a working Internet connection during the installation
  </ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>A Stage3 Approach</title>
<body>

<p>
A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
built for you. You will only need to build a few packages (such as system
logger, networking tools, ...) before you can boot into a base Gentoo
installation.
</p>

<p>
Choosing to go with a stage3 allows for the fastest install of Gentoo
Linux, but also means that your base system will have the optimization
settings that we chose for you (which to be honest, are good settings
and were carefully chosen to enhance performance while maintaining
stability). Stage3 is also required if you want to install Gentoo using
prebuilt packages or without a network connection.
</p>

<table>
<tr>
  <th>Stage3</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>Fastest way to get a Gentoo base system</ti>
</tr>
<tr>
  <th>+</th>
  <ti>
    You can still tweak your system
  </ti>
</tr>
</table>

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

<title>The Gentoo Installation CDs</title>
<subsection>
<title>Introduction</title>
<body>

<p>
The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
self-sustained Gentoo environment. They allow you to boot Linux from the CD.
During the boot process your hardware is detected and the appropriate drivers
are loaded. They are maintained by Gentoo developers.
</p>

<p>
All Installation CDs allow you to boot, set up networking, initialize your
partitions and start installing Gentoo from the Internet. We currently provide
two Installation CDs which are equaly suitable to install Gentoo from, as long 
as you're planning on performing an Internet-based installation using the latest
version of the available packages.
</p>

<p>
If you wish to install Gentoo without a working Internet connection, please use
the installation instructions described in the <uri
link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
</p>

<p>
The two Installation CDs that we currently provide are:
</p>

<ul>
  <li>
    The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable CD
    which sole purpose is to boot the system, prepare the networking and 
    continue with the Gentoo installation.
  </li>
  <li>
    The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same 
    abilities as the Minimal Installation CD. Additionally, it contains a 
    stage1 and several stage3 tarballs (optimized for the individual 
    subarchitectures). 
  </li>
</ul>

<p>
We currently only provide Installation CDs for the sparc64 architecture. Users
of sparc32 can use the experimental netboot images to install Gentoo from.
More information about netbooting can be found in our <uri
link="/doc/en/gentoo-sparc-netboot-howto.xml">Gentoo/SPARC Netboot
HOWTO</uri>.
</p>

<p>
To help you decide which Installation CD you need, we have written down the
major advantages and disadvantages of each Installation CD.
</p>

</body>
</subsection>
<subsection>
<title>Gentoo's Minimal Installation CD</title>
<body>

<p>
The Minimal Installation CD is called <c>install-sparc64-minimal-2005.1.iso</c> 
and takes up only 130 MB of diskspace. You can use this Installation CD to 
install Gentoo, but always with a working Internet connection only.
</p>

<table>
<tr>
  <th>Minimal Installation CD</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>Smallest download</ti>

  <ti>
    Contains no stages, no Portage snapshot, no prebuilt packages and is
    therefore not suitable for networkless installation
  </ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>Gentoo's Universal Installation CD</title>
<body>

<p>
The Universal Installation CD is called 
<c>install-sparc-universal-2005.1.iso</c> and consumes the entire surface of a 
650 MB CD. You can use this Installation CD to install
Gentoo, and you can even use it to install Gentoo without a working internet
connection, just in case you want to bring Gentoo to another PC than the one you
are currently installing Gentoo on :)
</p>

<table>
<tr>
  <th>Universal Installation CD</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>
    Contains everything you need. You can even install without a network
    connection.
  </ti>
</tr>
<tr>
  <th>-</th>
  <ti>Huge download</ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>Other CDs</title>
<body>

<p>
You might find a so-called <e>Package CD</e> on one of our mirrors. This CD is
no Installation CD but an additional resource that can be exploited during a 
networkless installation. It contains prebuilt packages (the so-called GRP set)
that allows you to easily and quickly install additional applications (such as
OpenOffice.org, KDE, GNOME, ...) immediately after the networkless Gentoo 
installation.
</p>

<p>
If you intend to use the Packages CD to quickly install additional software,
make sure that you use the same subarchitecture as the stage-3 tarball you use.

<title>Download, Burn and Boot a Gentoo Installation CD</title>
<subsection>
<title>Downloading and Burning the Installation CDs</title>
<body>

<p>
You have chosen to use a Gentoo Installation CD. We'll first start by 
downloading and burning the chosen Installation CD. We previously discussed 
the several available Installation CDs, but where can you find them?
</p>

<p>
You can download any of the Installation CDs (and, if you want to, a Packages 
CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
Installation CDs are located in the 
<path>releases/sparc/2005.1/sparc64/installcd</path> directory.
</p>

<p>
Inside that directory you'll find so-called ISO-files. Those are full CD images
which you can write on a CD-R.
</p>

<p>
In case you wonder if your downloaded file is corrupted or not, you can check its
MD5 checksum and compare it with the MD5 checksum we provide (such as
<path>install-sparc64-minimal-2005.1.iso.md5</path>). You can check the MD5 
checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
</p>

<p>
Another way to check the validity of the downloaded file is to use GnuPG to
verify the cryptographic signature that we provide (the file ending with
<path>.asc</path>). Download the signature file and obtain the public key:
</p>

<pre caption="Obtaining the public key">
$ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
</pre>

<p>
Now verify the signature:
</p>

<pre caption="Verify the cryptographic signature">
$ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
</pre>

<p>
To burn the downloaded ISO(s), you have to select raw-burning. How you
do this is highly program-dependent. We will discuss <c>cdrecord</c> and
<c>K3B</c> here; more information can be found in our <uri
link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
</p>

<ul>
  <li>
    With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
    file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device 
    path).
  </li>
  <li>
    With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
    you can locate your ISO file within the 'Image to Burn' area. Finally click
    <c>Start</c>.
  </li>
</ul>

</body>
</subsection>
<subsection>
<title>Booting the Installation CD</title>
<body>

<p>
Insert the Gentoo Installation CD in the CD-ROM and boot your system. During 
startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP, 
boot from the CD-ROM:
</p>

<pre caption="Booting the Installation CD">
ok <i>boot cdrom</i>
</pre>

<p>
You will be greeted by the SILO boot manager (on the Installation CD). Type in
<c>gentoo-2.4</c> and press enter to continue booting the 
system:
</p>

<pre caption="Continue booting from the Installation CD">
boot: <i>gentoo-2.4</i>
</pre>

<p>
Once the Installation CD is booted, you will be automatically logged on to the
system.
</p>

<p>
You should have a root ("#") prompt on the current console and can also switch
to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
started on by pressing Alt-F1.  You will also find a root prompt on the serial
console (<path>ttyS0</path>).
</p>

<p>
Continue with <uri link="#hardware">Extra Hardware Configuration</uri>.
</p>

</body>
</subsection>
<subsection id="hardware">
<title>Extra Hardware Configuration</title>
<body>

<p>
If not all hardware is supported out-of-the-box, you will need to load the
appropriate kernel modules.
</p>

<p>
In the next example we try to load the <c>8139too</c> module (support for 
certain kinds of network interfaces):
</p>

<pre caption="Loading kernel modules">
# <i>modprobe 8139too</i>
</pre>

</body>
</subsection>
<subsection id="useraccounts">
<title>Optional: User Accounts</title>
<body>

<p>
If you plan on giving other people access to your installation
environment or you want to chat using <c>irssi</c> without root privileges (for
security reasons), you need to create the necessary user accounts and change 
the root password.
</p>

<p>
To change the root password, use the <c>passwd</c> utility:
</p>

<pre caption="Changing the root password">
# <i>passwd</i>
New password: <comment>(Enter your new password)</comment>
Re-enter password: <comment>(Re-enter your password)</comment>
</pre>

<p>
To create a user account, we first enter their credentials, followed by
its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
In the next example, we create a user called &quot;john&quot;.
</p>

<pre caption="Creating a user account">
# <i>useradd -m -G users john</i>
# <i>passwd john</i>
New password: <comment>(Enter john's password)</comment>
Re-enter password: <comment>(Re-enter john's password)</comment>
</pre>

<p>
You can change your user id from root to the newly created user by using
<c>su</c>:
</p>

<pre caption="Changing user id">
# <i>su - john</i>
</pre>

</body>
</subsection>
<subsection>
<title>Optional: Viewing Documentation while Installing</title>
<body>

<p>
If you want to view the Gentoo Handbook (either from-CD or online) during the
installation, make sure you have created a user account (see <uri
link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
go to a new terminal and log in.
</p>

<p>
If you want to view the documentation on the CD you can immediately run
<c>links2</c> to read it:
</p>

<pre caption="Viewing the on-CD documentation">
# <i>links2 /mnt/cdrom/docs/handbook/html/index.html</i>
</pre>

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

<pre caption="Viewing the Online Documentation">
# <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml</i>
</pre>

<p>
You can go back to your original terminal by pressing <c>Alt-F1</c>.
</p>

</body>
</subsection>
<subsection>
<title>Optional: Starting the SSH Daemon</title>
<body>

<p>
If you want to allow other users to access your computer during the
Gentoo installation (perhaps because those users are going to help you
install Gentoo, or even do it for you), you need to create a user
account for them and perhaps even provide them with your root password 
(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
</p>

<p>
To fire up the SSH daemon, execute the following command:
</p>

<pre caption="Starting the SSH daemon">
# <i>/etc/init.d/sshd start</i>
</pre>

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

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

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

266	<title>The Gentoo Installation CDs</title>
267	<subsection>
268	<title>Introduction</title>
269	<body>
270
271	<p>
272	The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
273	self-sustained Gentoo environment. They allow you to boot Linux from the CD.
274	During the boot process your hardware is detected and the appropriate drivers
275	are loaded. They are maintained by Gentoo developers.
276	</p>
277
278	<p>
279	All Installation CDs allow you to boot, set up networking, initialize your
280	partitions and start installing Gentoo from the Internet. We currently provide
281	two Installation CDs which are equaly suitable to install Gentoo from, as long
282	as you're planning on performing an Internet-based installation using the latest
283	version of the available packages.
284	</p>
285
286	<p>
287	If you wish to install Gentoo without a working Internet connection, please use
288	the installation instructions described in the <uri
289	link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
290	</p>
291
292	<p>
293	The two Installation CDs that we currently provide are:
294	</p>
295
296	<ul>
297	<li>
298	The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable CD
299	which sole purpose is to boot the system, prepare the networking and
300	continue with the Gentoo installation.
301	</li>
302	<li>
303	The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
304	abilities as the Minimal Installation CD. Additionally, it contains a
305	stage1 and several stage3 tarballs (optimized for the individual
306	subarchitectures).
307	</li>
308	</ul>
309
310	<p>
311	We currently only provide Installation CDs for the sparc64 architecture. Users
312	of sparc32 can use the experimental netboot images to install Gentoo from.
313	More information about netbooting can be found in our <uri
314	link="/doc/en/gentoo-sparc-netboot-howto.xml">Gentoo/SPARC Netboot
315	HOWTO</uri>.
316	</p>
317
318	<p>
319	To help you decide which Installation CD you need, we have written down the
320	major advantages and disadvantages of each Installation CD.

330	The Minimal Installation CD is called <c>install-sparc64-minimal-2005.1.iso</c>
331	and takes up only 130 MB of diskspace. You can use this Installation CD to
332	install Gentoo, but always with a working Internet connection only.

367	The Universal Installation CD is called

369	650 MB CD. You can use this Installation CD to install
370	Gentoo, and you can even use it to install Gentoo without a working internet

400	You might find a so-called <e>Package CD</e> on one of our mirrors. This CD is
401	no Installation CD but an additional resource that can be exploited during a
402	networkless installation. It contains prebuilt packages (the so-called GRP set)
403	that allows you to easily and quickly install additional applications (such as
404	OpenOffice.org, KDE, GNOME, ...) immediately after the networkless Gentoo
405	installation.
406	</p>
407
408	<p>
409	If you intend to use the Packages CD to quickly install additional software,
410	make sure that you use the same subarchitecture as the stage-3 tarball you use.

419	<subsection>
420	<title>Downloading and Burning the Installation CDs</title>
421	<body>
422
423	<p>
424	You have chosen to use a Gentoo Installation CD. We'll first start by
425	downloading and burning the chosen Installation CD. We previously discussed
426	the several available Installation CDs, but where can you find them?
427	</p>
428
429	<p>
430	You can download any of the Installation CDs (and, if you want to, a Packages
431	CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
432	Installation CDs are located in the
433	<path>releases/sparc/2005.1/sparc64/installcd</path> directory.
434	</p>
435
436	<p>
437	Inside that directory you'll find so-called ISO-files. Those are full CD images
438	which you can write on a CD-R.
439	</p>
440
441	<p>
442	In case you wonder if your downloaded file is corrupted or not, you can check its
443	MD5 checksum and compare it with the MD5 checksum we provide (such as
444	<path>install-sparc64-minimal-2005.1.iso.md5</path>). You can check the MD5
445	checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
446	link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
447	</p>
448
449	<p>
450	Another way to check the validity of the downloaded file is to use GnuPG to
451	verify the cryptographic signature that we provide (the file ending with
452	<path>.asc</path>). Download the signature file and obtain the public key:
453	</p>
454
455	<pre caption="Obtaining the public key">
456	$ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
457	</pre>
458
459	<p>
460	Now verify the signature:
461	</p>
462
463	<pre caption="Verify the cryptographic signature">
464	$ <i>gpg --verify <signature file> <downloaded iso></i>
465	</pre>
466
467	<p>
468	To burn the downloaded ISO(s), you have to select raw-burning. How you
469	do this is highly program-dependent. We will discuss <c>cdrecord</c> and
470	<c>K3B</c> here; more information can be found in our <uri
471	link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
472	</p>
473
474	<ul>
475	<li>
476	With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
477	file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
478	path).
479	</li>
480	<li>
481	With K3B, select <c>Tools</c> > <c>CD</c> > <c>Burn Image</c>. Then
482	you can locate your ISO file within the 'Image to Burn' area. Finally click
483	<c>Start</c>.
484	</li>

490	<title>Booting the Installation CD</title>
491	<body>
492
493	<p>
494	Insert the Gentoo Installation CD in the CD-ROM and boot your system. During
495	startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP,
496	boot from the CD-ROM:
497	</p>
498
499	<pre caption="Booting the Installation CD">
500	ok <i>boot cdrom</i>
501	</pre>
502
503	<p>
504	You will be greeted by the SILO boot manager (on the Installation CD). Type in
505	<c>gentoo-2.4</c> and press enter to continue booting the
506	system:
507	</p>
508
509	<pre caption="Continue booting from the Installation CD">
510	boot: <i>gentoo-2.4</i>
511	</pre>
512
513	<p>
514	Once the Installation CD is booted, you will be automatically logged on to the
515	system.
516	</p>
517
518	<p>
519	You should have a root ("#") prompt on the current console and can also switch
520	to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
521	started on by pressing Alt-F1. You will also find a root prompt on the serial
522	console (<path>ttyS0</path>).

536	If not all hardware is supported out-of-the-box, you will need to load the
537	appropriate kernel modules.
538	</p>
539
540	<p>
541	In the next example we try to load the <c>8139too</c> module (support for
542	certain kinds of network interfaces):

554
555	<p>
556	If you plan on giving other people access to your installation
557	environment or you want to chat using <c>irssi</c> without root privileges (for
558	security reasons), you need to create the necessary user accounts and change
559	the root password.
560	</p>
561
562	<p>
563	To change the root password, use the <c>passwd</c> utility:

567	# <i>passwd</i>
568	New password: <comment>(Enter your new password)</comment>
569	Re-enter password: <comment>(Re-enter your password)</comment>
570	</pre>
571
572	<p>
573	To create a user account, we first enter their credentials, followed by
574	its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
575	In the next example, we create a user called "john".

598	<body>
599
600	<p>
601	If you want to view the Gentoo Handbook (either from-CD or online) during the
602	installation, make sure you have created a user account (see <uri
603	link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
604	go to a new terminal and log in.
605	</p>
606
607	<p>
608	If you want to view the documentation on the CD you can immediately run

617	However, it is preferred that you use the online Gentoo Handbook as it will be
618	more recent than the one provided on the CD. You can view it using <c>links2</c>
619	as well, but only after having completed the <e>Configuring your Network</e>

639	If you want to allow other users to access your computer during the
640	Gentoo installation (perhaps because those users are going to help you
641	install Gentoo, or even do it for you), you need to create a user
642	account for them and perhaps even provide them with your root password
643	(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
644	</p>
645
