It's possible - and many people do it - to install many distributions with FAI successfully: Redhat (especially RHEL5, others should not be a major problem), Fedora, SuSE/Novell, Ubuntu, Debian. They might have some glitches (depending on distribution, it might be that softupdates and/or fai-cd are a bit problematic) but in general it's stable and usable.
Support for Linux distributions other then Debian is available since 2011. FAI
can install Linux distributions like Redhat, CentOS,
Scientific Linux Cern, Fedora, openSUSE, SuSE, Ubuntu and of course Debian.


Since FAI 3.1.8 already has the most important things integrated:
Read the [https://lists.uni-koeln.de/pipermail/linux-fai/2011-September/009243.html announcement] including a small HowTo.


* unpacking a base.tgz named CLASS.tar.gz from the configspace directory "basefiles"
=== Distribution specific stuff ===
** Alternative to this, via hook: http://www.mail-archive.com/linux-fai@uni-koeln.de/msg02001.html
* using other package managers (see install_packages or it's doc - I am not sure where and if there exists docs but the sources)


There are some ubuntu classes here: http://faiwiki.informatik.uni-koeln.de/images/b/b1/Fai-configspace.tar.gz
==== Ubuntu ====
Just get the basefile for Ubuntu from
https://fai-project.org/download/basefiles/ and use the Ubuntu
examples from /usr/share/doc/fai-doc/examples/simple.


And there is a RHEL5 example configspace here: http://svn.debian.org/wsvn/fai/people/lazyboy/rhel-install-fixes_3.1.8/

FAI 4.0 includes examples for installing CentOS 5 and 6.

A Quick overview:
==== Scientific Linux Cern ====
FAI 4.0 can also install SCL 5 and 6.
Ready-made basefiles are available at https://fai-project.org/download/basefiles/.


* build a minimal base image (here, the make-fai-base-tgz from  [http://svn.debian.org/wsvn/fai/people/lazyboy/fai-distributions/ svn://svn.debian.org/svn/fai/people/lazyboy/fai-distributions ] can help you, but is not required - you can build your base image as you wish) and put it into MY-DISTRIBUTION-NAME.tar.gz in the configspace/basefiles
==== RHEL5 and 6 ====
* add the install host to the class MY-DISTRIBUTION-NAME
Redhat Enterprise Linux 5 and 6
* write a hook prepareapt.MY-DISTRIBUTION-NAME to replace the stuff specific for the distribtuion of the fai server with something suitable to get your specific distribution ready to install packages. the actual prepareapt task must be skipped
* check that the package lists of the classes of that host are compatible for your distribution. read man install-packages to learn about available package managers for non-dpkg distributions
* install as usual


As we have not much feedback on this topic, which makes it hard to know if it works, or to make it better, please report success or failure of this methods on the FAI mailing lists!
This should work in the same way as CentOS and SLC.

Should work with more recent versions, too.
Your need a redhat specific basefile - see below.
 
You need cfengine from here(or somewhere else) to do softupdates on a running system: http://ftp.rpmforge.net/pub/dag/redhat/el5/en/i386/dag/RPMS/cfengine-2.2.1-1.el5.rf.i386.rpm
 
And you need a config space with some specific stuff for the redhat systems.
 
Check out http://svn.debian.org/wsvn/fai/people/lazyboy/rhel-install-fixes_3.1.8/examples/rhel-install-demo and add ths stuff you need to your current config space.
 
It should be no problem to mix this into your existing Debian configspace.
 
== bootstrapping the base images  for other distributions ==
The stuff previously mentioned on [http://svn.debian.org/wsvn/fai/people/lazyboy/fai-distributions/ svn://svn.debian.org/svn/fai/people/lazyboy/fai-distributions ] helps with other debian-like distributions.
 
For Fedora/Redhat like distributions, you can use yum.
 
For example, to bootstrap rhel5, after having created a local mirror, I create such a yum.conf file:
 
<pre>
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
exclude=*-debuginfo
gpgcheck=0
obsoletes=1
reposdir=/dev/null
plugins=1
 
 
[base]
protect=0
name=Red Hat Enterprise Linux 5
#baseurl=file:///nfs/rhel5/Server
#baseurl=http://localhost/mirrors/rhel/5/Server/
baseurl=file:///var/www/mirrors/rhel/5/Server/
enabled=1
</pre>
 
Then I call this script:
 
<pre>
#! /bin/sh
tmp=`mktemp -d`
 
yum -c yum.conf --installroot=$tmp -y install yum dhclient
cp rhel5.repo  $tmp/etc/yum.repos.d/
mount -o bind /proc $tmp/proc
chroot $tmp yum groupinstall -y Core
chroot $tmp yum clean packages
 
echo "chroot created in tmp=$tmp"
oldpwd=$PWD
cd $tmp
umount ./proc
 
tar cvfz $oldpwd/DIST-RHEL_5.tar.gz .
 
cd -
 
echo "chroot created in tmp=$tmp"
</pre>
 
And I'm done. This leads to a working install when using my example configspace mentioned above.
 
There are some issues left, so this currently works for dirinstall, only, out of the box. I had to install some additional packages (will add the list later) manually in the nfsroot, and then netinstall via pxe worked, too.
 
To know what you have to install manually in the nfsroot, check the output of make-fai-nfsroot -v - at one point, quite some packages are dropped with the message that they aren't available, but they can be installed just normal, and are perfectly there. Without this, make-fai-nfsroot finishes with "success", but is unable to install a machine nicely via network install.

Status

Support for Linux distributions other then Debian is available since 2011. FAI can install Linux distributions like Redhat, CentOS, Scientific Linux Cern, Fedora, openSUSE, SuSE, Ubuntu and of course Debian.

Read the announcement including a small HowTo.

Distribution specific stuff

Ubuntu

Just get the basefile for Ubuntu from https://fai-project.org/download/basefiles/ and use the Ubuntu examples from /usr/share/doc/fai-doc/examples/simple.


CentOS

FAI 4.0 includes examples for installing CentOS 5 and 6. Ready-made basefiles are available at https://fai-project.org/download/basefiles/. Sample log files for a CentOS 6 installation can be found here

Scientific Linux Cern

FAI 4.0 can also install SCL 5 and 6. Ready-made basefiles are available at https://fai-project.org/download/basefiles/.

RHEL5 and 6

Redhat Enterprise Linux 5 and 6

This should work in the same way as CentOS and SLC.

SuSE

A more verbose description on how to do this with SLES9 is available here

Bootstrapping the base images for other distributions

Have a look at examples/simple/basefiles/mk-basefile. Works for Ubuntu, CentOS, SLC. For RPM based distributions it uses rinse, which also support some old versions of OpenSUSE.
