md driver at boot time

[Mark J Strawcutter]

System has 4 scsi disks - sda/b/c/d

sda and sdc are level1 raidset to be mounted as root.

sdd just happens to have been used as part of a root raidset during testing.

RHEL4 keeps constructing raidset using sdd at boot time.

I've tried combinations of raid=noautodetect and md=1,/dev/sda,/dev/sdb
kernel params at boot to force it to do the right thing but nothing seems
to work.

Isn't there some way to "force" proper construction of the raidset at boot
time short of moving disks around?
