    This is a hack until we get around to fixing it.

    Packet now returns 422 if the machine is not in the correct power state
    for actions.  This is particularly annoying for on.  poweron returns
    an error if the machine is already on.  Ignore all 422s now.

    The better fix is to do our own stage management of power.
    Ask and then do.
