FAI for Ubuntu/karmic

Hi Developers,

after a successful workshop with Thomas, I would like to sent some
hints and patches for getting FAI working on Ubuntu/karmic to
install Ubuntu/karmic.

I've checkout the latest subversion of fai:
svn co svn://svn.debian.org/svn/fai/trunk fai-sources

After applying the attached patches (fai-ubuntu-control.patch,
fai-ubuntu-upstart.patch) you can successfully build and install the fai packages:

$ cd fai-sources
$ dpkg-buildpackage
$ cd ..
$ sudo dpkg -i fai-quickstart_3.3_all.deb fai-doc_3.3_all.deb fai-server_3.3_all.deb

In Ubuntu there is no package with the name "syslinux-common", the
package name here is "syslinux". 

Ubuntu switched to upstart as init replacement, so we need to start
the main fai script via upstart.  In the patch I check the
environment variable UPSTART_JOB, if fai is called via upstart init
application.

After that you can create a new /etc/fai-karmic directory and modify
the configuration to match Ubuntu package names. See
fai-ubuntu-NFSROOT.patch as example. Here we have used unionfs-fuse
instead of aufs2. Ubuntu removed the aufs2 binary packages in
Karmic.

After that I've setup a local repository with the fai packages for
the installation and client system:

# mkdir -p /srv/www/fai/
# cp fai-client_3.3_all.deb fai-nfsroot_3.3_all.deb /srv/www/fai/
# cd /srv/www/fai
# dpkg-scanpackages . /dev/null |gzip -v9 > Packages.gz 

My apache DocumentRoot is /srv/www. My /etc/fai/apt/sources.list
contains following line for the local repository:
deb http://10.1.1.1/fai/ ./

The next step is to call fai-setup:

# fai-setup -C /etc/fai-karmic -v

If this successfully creates a nfsroot, you need to manually configure upstart:
(should I create a patch for make-fai-nfsroot?)

# chroot /srv/fai/nfsroot-karmic/live/filesystem.dir
# mkdir /etc/unused
# mv /etc/init/* /etc/unused/
# cp /etc/unused/mountall* /etc/init
# cp /etc/unused/*udev* /etc/init
# cp /etc/unused/hostname.conf /etc/init
# exit
# cp $HOME/fai-sources/upstart/fai.conf /srv/fai/nfsroot-karmic/live/filesystem.dir/etc/init

After that you could use the patch fai-ubuntu-configspace.patch to
create a Ubuntu/karmic compatible configuration including grub2
installation.

Then you can use fai-chboot:
# fai-chboot -F -I -v -C /etc/fai-karmic/ faiclient

After booting Ubuntu we found a small bug in the fstab generation.
The swap entry shouldn't be checked via fsck, this line:
/dev/sda5       none    swap    rw      0       2
Should be generated like this:
/dev/sda5       none    swap    rw      0       0

Attached is a fai.log from the installation. There might be a change
needed in setup-storage, a variable is not initialized.

One open bug is that the keymap while the installation is running
is not set correctly, see:

Executing GERMAN.var
++ KEYMAP=de-latin1-nodeadkeys
Loading keymap(s) de-latin1-nodeadkeys .../usr/bin/ckbcomp: Can not
find file "symbols/de-latin1-nodeadkeys" in any known directory

It would be nice if you could integrate some of the patches.
If you think they are to ugly, you could at least add them to the
enterprise edition ;)

best regards
 Waldemar
