Hmmm... yes.... So what about doing what SunOS documents instead of
what they actually do, i.e. have nfsd check permissions on the first
access by a given client for a given resource and then remember that
it's authorised (if it is). Would this require all nfsd's to share this
info? Is this getting too complex to be safe (as compared to just
always checking the current exports list on every access)?
