    I captured some data (as described above) and have made it available
    for anonymous ftp at
    "ftp://ftp.simplesystems.org/pub/outgoing/omnios/zoneadmd/".  I did
    this prior to updating the system due to suspecting that the problem
    would be cured by rebooting the system.

    As suspected, the problem was cured by rebooting the system.  Perhaps
    the parent zoneadmd is confused about the state after the new zone has
    been added and this confusion carries over to the child zoneadmd.

    The creation of the zone follows the example from the OmniOS Wiki
    except for the addition of a lofs mount.
