Some things do matter, but a machine in AFS can only have one sysname,
so you have to have a directory for any value @sys might take
(@sys, for those who don't use AFS, is a magical string that AFS will
substitute a machine-specific setting whenever you try and access it -
it's like a smart symlink. You can do things like have
and if you cd into into /afs/.../condor/@sys, you'll wind up in
either linux or solaris, depending on what machine you do the 'cd' from.
It lets you hard-code paths into things and have it just work, it's great.
