Because so far, I've commented out the array entry in fstab, I've added to mdadm.conf, and I've appended "nomdmonddf" "nomdmonisw" "nodmraid" and "raid=noautodetect" ALL to the kernel boot parameters
and it STILL TRIES TO START RAID.
I'm going to go on a rampage here.
Ah, the fact that the system doesn't even boot wasn't clear from the original rant.
Don't worry, I don't take offense, I can relate to the frustration.
Maybe a LiveCD + chroot?
EDIT: Also, just theorizing, but maybe this kind of thing needs to be changed inside the initrd.
