We want to support cases where / is a tmpfs with only /usr mounted in
from an OS image and where everything else is initialized and put
together on boot.

Similar, we want to support systems where / is reset via a "factory
reset" concept (and thus empty), then combined with /usr and comes up
properly initialized, with all mount points for /proc, /tmp, /sys and
so on created.
