Perserving permissions?

I just started using git to maintain some of my server config files. Leagues better than subversion, which I was previously using, but git still suffers from a key problem that subversion also has: lack of permission preservation.

I understand that versioning permissions might be a big request, but what about simply storing the permissions at 'git add' time, to be used at checkout time?

Right now I have to do 'git pull ; ./fix-perms' each time I update.
