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.
