git on afs

["Todd T. Fries" <todd@fries.net>]

I have always been frustrated by trying git on afs.

The other day I finally decided to look into why.

Looks like two reasons caused my frustrations.

1) git presumes that link() works fine across subdirs; in afs land,
   hardlinks do not succeed ever

2) git presumes that DTYPE(de) != DT_DIR .. means the dirent is not a dir
   this is not true for afs

I have been using this to sync several git trees, including linux-2.6 for the
past week without issues writing to a local afs server.

What do you guys think?
