  possibly off-topic but a long, long, *long* time ago, i wondered if
you could set up a network using *exclusively* NFSv4, and found it was
impossible -- at least one of the client programs required some
earlier version of NFS even if it wasn't being used.

  any clarification on whether one can run a *purely* NFSv4 network?
