There maybe a conflicting security requirement here. Lets say

with auth_sys to any old nfs client..

seems like that might be an issue ?

Clearly if a zone is in charge of its exports then there should be no
trivial way for a g-z admin to interfere short of using zlogin to
interfere from within that zone.

There are already precedents to *not* do that. A non-global zone must trust its global zone. This includes trusting the global zone to not:

* Halt it
* Edit its configuration files
* Run "zlogin svcadm disable ..."
* Run format and modify the layout of any disks that the zone is using

If there is data that HostA's global zone must not have access to, that data must be on a different computer.

The interesting question is: how this works on upgrade where the g-z had
shares inside a zone.  Do we move these shares into the zone, or do we
have a concept of zones that delegate sharing power to the g-z?
