There's no such UUID as far as I know, so I thought it safer to create a FreeBSD-specific one because we already have incompatibilities between operating systems for things like UFS and BSD labels. While ZFS may be portable, I'm not at all sure that different OSes are feature compatible and for that it's good to know where the ZFS originates from. Also, we may create an UUID with the intend that it's a common UUID, but getting other OSes to use that UUID is far from easy. -- Marcel Moolenaar xcllnt@mac.com
