Mike Frysinger 2b3122418d proc(5): Clarify the root symlink and mount namespaces 
If the target process is in a different mount namespace, the root
symlink actually shows that view of the filesystem.  As an example:

    /* Terminal 1 */
    $ unshare -Urnm
    # mount -t tmpfs tmpfs /etc
    # mount --bind /bin /dev
    # echo $$
    17168

    /* Terminal 2 */
    # ls /etc                       # Normal view of /etc files.
    # ls /proc/17168/root/etc       # Empty view of the tmpfs.
    # ls /dev                       # Normal view of /dev files.
    # ls /proc/17168/root/dev       # Contents of /bin files.
