If that mdadm.conf is on the root filesystem, then obviously it is of
no value for setting up the root filesystem.
You can:
- use an initramfs to do the work. Many distros do this for you.
The mdadm source contains some notes and scripts that I use.
- use a boot parameter of
md=3,/dev/hda3,/dev/hdc3
This is probably easiest, and as ide drives don't change their
names this should be safe.
initramfs is best though.
