The "df -h" shows:

none                  956M  640K  955M   1% /dev/shm
none                  956M   84K  956M   1% /var/run
none                  956M     0  956M   0% /var/lock
none                  956M     0  956M   0% /lib/init/rw

what are /var/lock and /lib/init/rw?
and what is "none" filesystem?
