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?
