Yeah, I do know the worry.  However, IBM *did* go away on us and
Teradactyl has been there year after year, supporting the AFS community,
participating on mailing lists and with the workshop, and clearly caring a
lot about AFS.  So I think you can do a lot worse.

That being said, we aren't currently using them -- we're still copying old
TSM binaries around.  *wry look*

I think the right long-term solution is going to be to add real AFS
support to Bacula.  I think it's closest otherwise, and ACL support is
something that it needs anyway.  Something that could do a standard
conversion of ACLs into some sort of portable standard format and could be
applied for POSIX ACLs, CIFS, and AFS, would be great and is the sort of
thing that I think Bacula would embrace.
