If you want to manage ZFS dataset from withing a jail, then you need to 
use zfs set jailed=on property (see man zfs). But this data set cannot 
be mounted as nullfs, it should be dedicated to the jail.

You don't need ezjail because ezjail cannot do anything more than you 
can do. It is just a shell script wrapper.
