 # that HA-in.named uses.  There are two cases to consider:
 # (1) This physical host gave up mastery of that logical host during
 # some earlier cluster reconfiguration.  In that case, the HA administrative
 # file system for the logical host will no longer be mounted so the
 # /HA administrative_file_system/hainnamed directory will not exist.
 # This method has no work to do, because the work got done during the
 # earlier cluster reconfiguration when this physical host first gave up
 # mastery of the logical host.
 # (2) This cluster reconfiguration is the one in which this physical
 # host is giving up mastery of the logical host.  In that case, the
 # administrative file system is still mounted when the stop_net method
 # is called and the /HA administrative_file_system/hainnamed directory
 # will exist.
