Hi all,
Just a FYI: I'm working on Ubuntu deployments at the moment, and I started a wiki page for this purpose: https://fedorahosted.org/cobbler/wiki/Ubuntu
I'll be documenting a method to deploy Ubuntu hands-off (so no human intervention), and hope to at least come up with a list of things that need to be extended in Cobbler to have better support for this distribution.
