This is the same as what is done with /rpool/ROOT and ZFS boot, with
"ROOT" being the confined area where we place BE's. An admin can still
create things there but this is the only place that we look for BE's.
Datasets outside this are not considered BE's but would be shared
between BE's as is done in the global zone now.
