The "nfsv4" was chosen to be compatible with "nfsv3" and "nfsv2",
which FreeBSD has used forever (I don't know who originally chose them).

I have thought of adding "vers=<n>" ("nfsv4" would still work) to be
more compatible with Solaris and Linux, but I've never gotten around
to it.
If no one else comes up with such a patch, I may get around to it someday, rick
