Isn't this missing some of the larger context?  df is just doing what
lots of other programs do: finding out what file systems one has,
and reporting statistics on them.  It sounds suboptimal to require
the maintainers of all these programs (coreutils, nautilus, etc.)
to rewrite their apps to deal with obscured entries.  Surely it would
be better to have the kernel ordinarily return just the ordinary entries,
and to return obscured entries only when they are specially requested.
That way, this issue would be isolated to the few bits of code that really
want to see obscured entries.
