[OpenAFS] AFS from NFS Mount

[Paul Blackburn]

Frank,

I see two problems with this:

a) You are relying on NFS for the security of your AFS fileserver data.
     This is not a good idea.

b) You have an extra layer of  "protocol covnersion" and an extra machine.
     This has to affect performance.
