Note (as you probably know) this first pass at labeled NFS only lets us
label files, not rpc calls--if we want the server to know who's doing
something (beyond the information the rpc headers already carry), we'll
need to implement rpcsec_gss v3, and that's a project for another day.
I've been assuming that makes server-side enforcement less useful for
now.
