The initrd tool, which was the default option, does this, and it is a
bad idea.

The initramfs tool, which is mostly shared with Ubuntu, is less stupid.
It uses mdadm and a loop to scan through the devices found on the
machine and find what RAID levels are required, then builds the RAID
arrays with mdrun.

Unfortunately, it still doesn't transfer /etc/mdadm.conf to the
initramfs, resulting in arrays changing position when constructed, to my
annoyance.   So, stupid, but not as stupid as the oldest tools.
