Subject: 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.
