You can't cfreate /dev/md0 on array discovery, since you need ioctl
on the device to activate it. What would be required is scanning of
all the block devices for *potential* raid arrays, and then guessing
what devices those were from the raid superblocks. It's a good chunk
of code that's not in udev ATM.
