I have vfs.nfsd.server_min_nfsvers=4 set on the server, and
when I mount_nfs -o nfsv3 on the client, the error the client
sees is

[tcp] terp:/packages: NFSPROC_NULL: RPC: Program/version mismatch; low
version = 4, high version = 4

Have to ^C to exit.

Nothing shows up in the server's log, but because of sloth I haven't
tried to make anything show up.  Maybe there's an option.

Best,
Russell
