It is not that /home/user/again will be empty. The old situation
is lifted to the new directory. Thus, in /home/user/again you'll
find what was in /home/user before the mount. In particular, if
/home/user/again was empty, then now /home/user/again/again will
be empty. Putting something in again/again/foo does not change
again, but after the umount there now is foo in again. All as expected.
