+# Tar up to 1.26 was unable to cope with directories that had once
+# been part of the dumped system and became separate mount points
+# afterwards.  The bug has been reported by Nathan Stratton Treadway,
+# who also proposed a fix and a testcase, on which the present one is
+# built.
+# Reported-by: Nathan Stratton Treadway <nathanst+bugtar@ontko.com>
