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