Absolutely, yes. I found this out because, for some reason that I don't
know, libvirtd wants a unique identifier. It defaults to looking at the
UUID from the BIOS. Unfortunately, SuperMicro boards have non-unique UUIDs.

Getting back to ZFS and /etc/hostid... I would think that a
randomly-generated /etc/hostid is probably sufficient. Whether that's
done in the libc, spl, or zfs package makes no difference to me.
