No. Maybe I should have said pseudo-filesystem but it is not the
subtree check feature (which, AFAIK, is not nfsv4-specific).

In nfsv4, if you add the fsid=0 or fsid=root option to an export like
/robert/day on nfssrv, the client has to mount /robert/day as nfssrv:/

Maybe, if you export /robert, it is assumed to have an fsid=root
option tacked on and you have to mount /robert as nfssrv:/
