Since the system is to be restored from the snapshot then I suppose most of steps 8 to 12 wouldn't be needed either. But what about step 5 before the restore: zpool export zroot zpool import -o cachefile=/var/tmp/zpool.cache zroot And then step 10 after running zfs receive cp /var/tmp/zpool.cache /mnt/boot/zfs/zpool.cache Are these steps needed when restoring from a snapshot? -- Mike Clarke
