[OpenAFS-port-darwin] Resource / Data Forks

[David Botsch]

Hmm... haven't tried mounting /Users in afsspace...

Don't see why it wouldn't work, though.

but what we do is to have our user home directories under /afs (so for our cell
msc, user home dirs would be in something like /afs/msc/home). Of course, the
netinfo db is updated to contain the right home directory locations.

There are two gotchas with OS X:
1. the uid of the user should match the afs id in pts db
2. the gui finder doesn't understand afs permissions and only looks at user
permissions and does not refresh itself properly

More details on these two gotchas are available in the archives for this list.

But, there are patches for afs which should work around these two issues. I
haven't personally tried them out, yet (bad me.. too many things on plate), but
will be doing so soon.
