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.
