Zones need to be on ZFS with a particular dataset layout so that boot
environments can be managed with beadm, pkg, etc.  That is, zone boot
environments have very similar requirements that global zone boot
environments have.

If the parent of the zonepath is itself a ZFS dataset, it does happen

That needs to be fixed.  It would cause zone boot environments to be
contained within global zone boot environments.  As new global zone
boot environments are created, you will end up with roughly 2x the
number of non-global zone BEs.  I normally use:

zfs create -o mountpoint=/zones rpool/zones

and would appreciate feedback as to whether others feel that this
should be the default behavior if the zonepath is /zones/<zonename>
and /zones doesn't already exist.
