    > cd /var
    > mkdir sub2
    > mount --move /tmp sub2

    attach the same instance of tmpfs to /tmp and /var, then you move the
    tmpfs from /tmp to the "/sub2" directory in the "/var" tmpfs
    _mountpoint_. It's kind of confusing behavior; but the directory
    tree and the mount tree are basically kind of separate entities in a

    Therefore, if you write the code as cleverly as possible, you are, by
    definition, not smart enough to debug it.
