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.
