In this case, given that the MAC address is in one of my machines, it can only be a UUID I can possibly generate (legally) and I can tell you that the UUID is not in use :-) If no-one has created their own UUID for ZFS, I'll re-use Craig's one so that he doesn't have to change his GPT. Any objections for using Craig's synthesized UUID for ZFS file systems? -- Marcel Moolenaar xcllnt@mac.com
