this really isn't related to busybox or mdev at all. /dev/shm should be a dedicated mount point (and from your mount, it already is) and is mounted by your system's boot scripts (which openrc does). for info on how to use mount, i'd suggest `man mount`. it documents various options to all the different filesystems. -mike
