I think I see why you may want it, but I don't think you'll get that
behavior from ZFS without hacking it. "zpool import -R root" is
probably your best bet. Alas altroot property is not persistent and
the pool would have to reimported on reboot. Another option may be to
backup/restore properties separately and ignore properties during
send/receive.
