sysinit is now a real runlevel that handles things like udev, dmesg and

mounting various bits in /dev and /sys.
init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems)
To make development of this easier we now return an empty RC_STRINGLIST
instead of a NULL for empty things.

If you don't have a udev init script installed, don't reboot your box OR
roll back to an older OpenRC version.
