Sorry, I'm very confused by now. It seems we are going to have some
troubles because of the two different device file types.

Here I just changed the linuxrc script in the initrd. I did not
create a /dev/md/0 in the initrd. In your patch you are trying to
create , why? Why does it work for me anyway? Are you
creating /dev/md/0 as old device file so it will allways exist and
will be overwritten by devfs, if enabled. I'm confused...

The /dev/md/0 hack is just to let lilo know we have the root device.
Otherwise it won't install the MBR. At the time I did this I was
running with devfs=nomount and therefore /dev/md/0 did not exist.
I couldn't find a way to force lilo to install anyway, am I blind?

What are you doing here? Since we don't have devfs at this time, we
can't copy /dev/md/0 to the initrd???

Maybe linuxrc solution could be easier:
raidautorun /dev/md/0
raidautorun /dev/md0
If we don't have devfs, the first line won't do anything but the
second statement should do the job. I'll try it later, maybe I'm
completely wrong...
