Just to toss an idea out here.  Imagine an accountant who has all of his 
work data on a big partition mounted at (let's say) /data.  If he wanted 
to hide a "second set of books," he could close his accounting program, 
unmount the partition and restart the program, so that /data now pointed 
to someplace on his main partition.  When he's done, he exits and 
remounts the partition.  The data's there, you can get to it if you know 
what to do, but I can't help but wonder how likely anybody, such as a 
forensic accountant, that was examining your system would even think of 
such a thing.  Any thoughts?
