Again, you're making it hard for people who are using this behavior (which,
intended or not, AFS has) to change PAGs, and I really wish you wouldn't. Now
that Linux has an in-kernel nfsd it won't matter, but I had also intended to
use this to allow a user-level nfsd to do the equivalent of Transarc knfs:
basically allow remote clients to have a PAG.
