We used to hide things after taking advantage of a mistake we made and thought
we'd lost a bunch of work when, in fact, it was just temporarily hidden.
Here's the technique:
When you want to mount something, you have to create a directory (if it
doesn't already exist) and then do the mount. The mounted file system then
appears at the directory, but what about things that were in that directory
prior to doing the mount? They're still there but no longer accessible (or
visible by any method I know). Later, if you umount, the old contents are
visible again.
I sometimes get myself into this by attempting to do a mount and not
noticing that it failed (maybe because I forgot to su or sudo). Then, I copy
a bunch of stuff into the mounted directory and then unmount (which also
fails). Being a good doobie, I then re-mount (but notice the error and do it
correctly this time) and look to see if my files are there -- which, of
course, they aren't. [I scratch my head at this point wondering what I did
wrong.] I then do a umount and, again, "ls" the directory and, voila, there
are the files. Aha!
If you never do this, I'll buy you a beer when you get to Heaven.
