Ugly hack I've been doing to create ZFS thingies under jumpstart/sparc,
but it works..

echo ZFS-stuff done
---8<--- run last in client_end_script ---8<---

zpool list | grep -w data > /dev/null || exit 0
echo /sbin/zpool export data
/sbin/zpool export data
echo /sbin/mount -F lofs /devices /a/devices
/sbin/mount -F lofs /devices /a/devices
echo chroot /a /sbin/zpool import data
chroot /a /sbin/zpool import data
The final step is the trick ;)
