<uri link="http://www.freebsd.org/">FreeBSD</uri> is a free (<uri |
| 56 |

| 57 |
Unix-like operating system. Back in 1993 when development of <uri |
| 58 |
link="http://www.386bsd.org/">386BSD</uri> stopped, two projects were born: |
| 59 |
<uri link="http://www.netbsd.org/">NetBSD</uri>, commonly known to run on a |
| 60 |
huge number of architetures, and FreeBSD which focuses mainly on the x86 |
| 61 |
platform. FreeBSD is renowned for its stability, performance and security, thus |
| 62 |
being used from small to huge companies all over the world. FreeBSD's current |
| 63 |
production release version is 5.4, which is also used as the foundation for the |
| 64 |
Gentoo/FreeBSD project. |

Gentoo/FreeBSD is an effort effort to provide a fully-capable FreeBSD operating |
| 75 |
system with Gentoo's design sensibilities. The long-term goal of the Gentoo/BSD |
| 76 |
project is to allow users to choose any combination of *BSD or Linux kernels, |
| 77 |
*BSD or GNU libc, and *BSD or GNU userland tools. |

<title>FreeBSD and Linux</title> |

| 87 |
Users migrating from Linux to FreeBSD commonly consider the two operating |
| 88 |
systems "almost the same". In fact, FreeBSD really shares a lot of similarities |
| 89 |
with Linux distributions in general. Nevertheless, it has some key differences |
| 90 |
that are worth noting: |
| 91 |
</p> |
| 92 |
|
| 93 |
<ul> |
| 94 |
<li> |
| 95 |
Contrary to Linux, which actually only refers to the kernel, FreeBSD is a |
| 96 |
complete operating system, consisting of a C library, userland tools and |
| 97 |
much more. This development approach makes the overall system very |
| 98 |
consistent |
| 99 |
</li> |
| 100 |
<li> |
| 101 |
Contrary to the Linux kernel, FreeBSD development is not led by one person, |
| 102 |
but instead managed by a small group of people called the <uri |
| 103 |
link="http://www.freebsd.org/doc/en_US.ISO8859-1/articles/contributors/staff-core.html">Core |
| 104 |
Team</uri>. |
| 105 |
</li> |
| 106 |
</ul> |
| 107 |
|
| 108 |
<p> |
| 109 |
Besides, FreeBSD also has some technical differences which set it apart |
| 110 |
from Linux. Some of them are very important to know, even if you don't plan on |
| 111 |
joining the Gentoo/FreeBSD development effort: |
| 112 |
</p> |
| 113 |
|
| 114 |
<ul> |
| 115 |
<li> |
| 116 |
To get run-time dynamic linking fuctions like <c>dlopen()</c>, programs do |
| 117 |
not need to be linked against libdl like on GNU/Linux. Instead they are |
| 118 |
linked against libc |
| 119 |
</li> |
| 120 |
<li> |
| 121 |
FreeBSD doesn't have an official tool for kernel compilation, thus you'll |
| 122 |
have to resolve feature dependecies on your own |
| 123 |
</li> |
| 124 |
<li> |
| 125 |
FreeBSD uses UFS/UFS-2 as its filesystems and has no official support for |
| 126 |
e.g. ReiserFS or XFS. However, there are projects for adding read-only |
| 127 |
support for these filesystems. However, accessing ext2/ext3 partitions is |
| 128 |
already possible, but you cannot install your system on them. |
| 129 |
</li> |
| 130 |
</ul> |

<title>Installing Gentoo/FreeBSD</title> |

<section> |
| 139 |
<title>Installation instructions</title> |
| 140 |
<body> |
| 141 |
|
| 142 |
<p> |
| 143 |
After this short introduction, it's about time to finally install |
| 144 |
Gentoo/FreeBSD. Unfortunately, we currently lack our own installation media, so |
| 145 |
you have to choose between two alternative installation methods. The first |
| 146 |
would be to use an existing FreeBSD installation to partition your hard drive |
| 147 |
and use it as a base for installing Gentoo/FreeBSD. Alternatively, you can also |
| 148 |
use the excellent <uri link="http://www.freesbie.org/">FreeSBIE LiveCD</uri> as |
| 149 |
an installation medium for Gentoo/FreeBSD. |
| 150 |
</p> |
| 151 |
|
| 152 |
<p> |
| 153 |
Before you can begin with the installation, you have to setup a hard disk for |
| 154 |
use with Gentoo/FreeBSD. This can either be done via <c>sysinstall</c> |
| 155 |
(available from a current FreeBSD installation as well as from within FreeSBIE) |
| 156 |
or by manually using the commands <c>fdisk</c>, <c>disklabel</c> and |
| 157 |
<c>newfs</c>. If you have never set up a FreeBSD system before, |
| 158 |
<c>sysinstall</c> may be the better option for you. If you face difficulties |
| 159 |
while partitioning or formatting your hard disks, have a look at the great |
| 160 |
<uri link="http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/">FreeBSD |
| 161 |
Handbook</uri> or hop onto <c>#gentoo-bsd</c> on the Freenode IRC server. |
| 162 |
</p> |
| 163 |
|
| 164 |
<p> |
| 165 |
Once you're done setting up your disks, you have to create a mount point for |
| 166 |
your Gentoo/FreeBSD installation and mount all the necessary partitions. |
| 167 |
</p> |
| 168 |
|
| 169 |
<pre caption="Creating a mount point and mounting partitions"> |
| 170 |
# <i>mkdir /mnt/gfbsd</i> |
| 171 |
<comment>(Replace X with the correct numbers for your hard disk.)</comment> |
| 172 |
# <i>mount /dev/adXsXa /mnt/gfbsd</i> |
| 173 |
</pre> |
| 174 |
|
| 175 |
<p> |
| 176 |
Now that you have mounted the target partition, it is time to fetch and unpack |
| 177 |
a stage3 tarball. |
| 178 |
</p> |
| 179 |
|
| 180 |
<pre caption="Obtaining and unpacking a stage3 tarball"> |
| 181 |
<comment>(Any other Gentoo mirror which includes the experimental/ directory will also work.)</comment> |
| 182 |
# <i>wget http://gentoo.osuosl.org/experimental/x86/freebsd/stage3-x86-fbsd-20050811.tar.bz2</i> |
| 183 |
# <i>cp stage3-x86-fbsd-20050811.tar.bz2 /mnt/gfbsd/</i> |
| 184 |
# <i>cd /mnt/gfbsd/</i> |
| 185 |
# <i>tar -jxvpf stage3-x86-fbsd-20050811.tar.bz2</i> |
| 186 |
<comment>(You can delete the tarball with the following command if you want to.)</comment> |
| 187 |
# <i>rm stage3-x86-fbsd-20050811.tar.bz2</i> |
| 188 |
</pre> |
| 189 |
|
| 190 |
<p> |
| 191 |
In order for your install to work, you need to mount the <path>/dev</path> |
| 192 |
filesystem from the currently running system into the Gentoo/FreeBSD mount |
| 193 |
point before proceeding with the chroot. |
| 194 |
</p> |
| 195 |
|
| 196 |
<pre caption="Mounting the /dev filesystem and chrooting"> |
| 197 |
# <i>mount -t devfs none /mnt/gfbsd/dev/</i> |
| 198 |
# <i>chroot /mnt/gfbsd/ /bin/bash</i> |
| 199 |
</pre> |
| 200 |
|
| 201 |
<p> |
| 202 |
Once inside the chroot you have to obtain a copy of the Gentoo/FreeBSD overlay. |
| 203 |
If you are not a Gentoo developer, you can get it from the mirror provided by |
| 204 |
<mail link="carpaski@g.o">Nick Jones</mail>. Theoretically, you could |
| 205 |
put this overlay in any directory you like, but from now on we will just assume |
| 206 |
that you have downloaded it to <path>/usr/local/portage/gentoo-freebsd</path>. |
| 207 |
