I seem to fail to understand why the heck that is the business of the
NFS RFC to have an opinion about. That's part of what namespace the
server wants to export. The fact that Sun does it brokenly, requiring
the clients to be aware of details that should be internal to the
server, is no reason to perpetualize the error, IMNSHO.
