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.
