Wheel, anyway there are more places that uses /dev/null (inside at 
rc.d/functions).

Anyway a system without initramfs should have a minimal /dev/ with 
console (othewise init will fails silently and no startups messages you 
will see) and if no null dev, messages without colors, until 
rc.d/functions is re-read (in rc.multi).
