    Change the :Z mount flag to :z

    Leaving this with the capital Z limits access to this file
    to the other novajoin container. This can cause the other
    container to malfunction. At the very best, the other
    container will restart, relabeling the file with it's
    settings, which has the proper value of lower z.
