  21 # Tar up to 1.26 was unable to cope with directories that had once
  22 # been part of the dumped system and became separate mount points
  23 # afterwards.  The bug has been reported by Nathan Stratton Treadway,
  24 # who also proposed a fix and a testcase, on which the present one is
  25 # built.
