I'm not trying to put blame.  But I think we need to sort this out
somehow - plenty of devices ship without a uuid and a system log
warning is not useful.  So I guess we need to slowly deprecate this
attribute and add proper ones for nguid/uuid.  But I can't really come
up with good names for them.
