[OpenAFS] AFS from NFS Mount

[Brent Johnson]

Okay. Interesting.  I thought it was a long-standing rule (don't ask 
where I got this from) that you couldn't use an NFS-mounted filesystem 
as a vice partition on a fileserver.  We're running Solaris and have 
some Network Appliance Filers running around.  So you're saying that I 
could mount share from the filer on my Solaris 8 fileserver and make 
that my vice partition?
