Authenticate it. I recommend getting and installing kth-krb and using
kauth (which it comes with) for this, but of course it means leaving a
kerberos srvtab around "somewhere"

Killing afsd is bad. If the script isn't stopping afsd, it's most likely
because you have references in /afs; Sadly starting in 2.4 it seems
fuser/lsof isn't showing all references in AFS, but since patches were
integrated a few versions ago I have been unable to make AFS not shut down
when I could establish nothing was actually referencing /afs.

the afsd processes shouldn't be terminating themselves. also, you should
unload and reload the kernel module if you restart afs. the script will do
that for you.
