Sounds like a question for the Linux NFS mailing list. All I can mention is
that most NFS servers use an fsid to uniquely identify a file system on the
server. It is often a part of the file handle.
Anyhow, thanks for letting us know. If someone reports a similar problem,
we can suggest trying adding fsid=<N> to their Linux server's export line.
Thanks, rick
