rc.d/tmp: tmpfs support not entirely complete?

I've just had a quick look at rc.d/tmp and noticed that it uses mount_md 
function for the actual mounting.  The function is quite smart and can use 
either tmpfs or a memory disk depending on the configuration.
But mount_tmpmfs in rc.d/tmp tests only for an md device when it checks whether 
/tmp is already a "memory filesystem".
