Friends, Romans, Cobbler users,
Seeing I personally have a few uses for a better templating system
than what I have now, I'm moving Cobbler back to using Cheetah for
kickstart templating in 0.4.0. Originally the move away from Cheetah
was done to accomdate RHEL3 based cobbler servers, but I can't
continue to justify not having a good templating engine, so I'm
cutting those lose.
Kickstart files you have now will be unaffected (and will still work
as is), though now "TEMPLATE::foo" just becomes an alias for the much
simpler $foo. Variables that aren't found in --ksmeta arguments (say
$thisisnotavariable) just don't get expanded.
I'll probably bundle Cheetah in the cobbler RPM (as I did before) to
make RHEL4 happy (good for Centos for having python-cheetah in the
repository).
This will be in the 0.4.0 release and is already pushed out to the
public hg repo if you want to get a jump start on testing it out.
You can learn to use the full power of Cheetah for your kickstart
templates here: http://www.cheetahtemplate.org/learn.html

I lied somewhat :)
Cobbler 0.4.0 will apparently require escaping of certain dollar signs
in kickstart files. Particularly, the list hard drives macro in
/etc/cobbler/kickstart-fc6.ks for instance, will be changed so it will
work for new users. Those users already using those files will need to
make those changes manually or to copy
/etc/cobbler/kickstart-fc6.ks.rpmnew over the other file -- the RPM is
set up not to overwrite files that users might have modified.
Per the Cheetah manual:
Placeholders and directives can be escaped by putting a backslash before
them. |\$var| and |\#if| will be output as literal text.
