Git has a bad history with mapped drives in windows. It's also usually a bad idea to use git over the network (and most mapped drives are over the network and not local between virt. machines).

I would advise not to use this setup since for the past two years that git has sometime worked and sometimes not with this setup. (It's not just seperate git dir, a git dir at all over a smb share have been problematic).

(This is probably something we should have in a test-suite somewhere.)
