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?
I see no reason why not. On all machines at one site nfs4 is used to provide
idmap capability. That's the only kind of mount used, and a long look with
wireshark shows all nfs packets were V4, so I empirically conclude it works.
You have to diddle the firewall to get nfs3 to work IIRC.
