tmpfs only takes up ram if it is used. With that empty, it's probably taking only a few bytes (in kernel structures) just to say that it exists. 'shm' is 'shared memory' - it is basically an in-ram filesystem that allows programs to share chunks of ram while sticking to the unix philosophy of "everything is a file". _______________________________________________ arch mailing list [email protected] http://www.archlinux.org/mailman/listinfo/arch
