It's a great idea, something I would like to do, and something I've 
suggested before.  You could dig through the mailing list archives, if 
you're motivated.

I actively use git to version, store and distribute an exim mail 
configuration across six servers.  So far my solution has been a 'fix 
perms' script, or using the file perm checking capabilities of cfengine.

But it would be a lot better if git natively cared about ownership and 
permissions (presumably via an option).
