I read your "ignore my question" message, but wanted to comment more
generally for other people's benefit.

Basically, AFS wants to accord "superuser" permissions to people with
system:administrators tokens instead of to people who happen to be
root on the client machine.  Moreover, the server wants to enforce
these policies, not the client.  So anything involving suser() is
going to be wrong.  I think there is already code in there prior to
rev 1.112 which will cause problems with AFS, but I haven't tested
anything.

(POSIX always refers to "appropriate permissions," incidentally, not
being root.)
