8.04-1 won't boot from degraded raid

[Michael Hipp]

I just loaded a small LAN server with 8.04-1 server. It has two identical disks 
in a RAID1 configuration. Works great as long as both disks are online. But if 
I disconnect either disk it drops into a BusyBox shell and tells me that my 
RAID is degraded and I can boot from it if only I will type mdadm -R /dev/md0. 
But that command does nothing toward getting it to boot.

Why is it doing this? Can I somehow make this thing boot automatically even if 
degraded?

(If I didn't want it to boot anyways I wouldn't have installed RAID.)
