The format it uses on the wire is separate XDR encoding of each of the fields
in the uuid_v1 struct, counting the elements of the node[] array separately.
I'm not sure that the servers actually parse the contents of the UUID, but I
can't be sure as I don't have access to the source for all of them.
OpenAFS and AuriStor will at least accept the version field being 4, however.
