 I think that this problem is closely related to the fact that the
 permissions on the original mountpoint directory affect the ability
 of a process to access ".." from the mounted filesystem root.  See
 CAVEATS in mount(8) for details.  AFAIK fts(3) uses chdir("..")
 when traversing a directory tree unless FTS_NOCHDIR was specified
 to fts_open(3).  FTS_NOCHDIR is usually no good because it limits
 the depth of the tree fts(3) is able to traverse to PATH_MAX.
 
 Would you agree now that there is no bug to fix and so this PR can
 be closed?
