Oh, there are tricks that have been used for decades in Unix that will
still work in Linux.  For instance, create a directory as a mountpoint;
put some files and directories in it, then mount an filesystem over it.
I believe that still works in Linux.

Another trick used to be to remove the actual ".." directory entry with
an entry that really points off to another directory; this was called a
'hyperspace link'.  I don't know if that still works, but it's an example
of the kind of things crackers _can_ do to hide files and directories.
