We are using svn to manage our configuration since a few weeks, before the whole
thing was based on CVS, which is completely supported by FAI already and works
very well. Usings tags you can even commit to the repository, as long as you
don't mark the changes as stable.

However, I do not suggest automated updates in a mission-critical environment,
not even on Debian-stable. We do not even run manually invoked concurrent
updates on all hosts anymore as this, e.g., might break both of your DNS servers
at once, which happened here :-) 

HTH,
Michael
