I already cherry-picked your [f333bc0] (nodmraid boot option), but I have some
doubts about [54b8d6f]. Reverting that change will break all broken

Ok, then /dev/sdc will not be removed.

Interesting, thanks for the info. Sorry to flog this to death.
Online ubuntu docs with respect to dmraid are definitely somewhat
scattered and of varying levels of authority. From a naive "newer is
better" perspective, the page you mention was last edited 2008-08-06,

Yes, i understand that it's a driver for BIOS magic that i'd rather not
use.

Is there a usage scenario where this
I want to reiterate that the original bug was reported against the
_alternate_ install cd. If i understand correctly, the alternate
install cd is required to install using any raid functionality. The
initramfs installed by the alternate cd included mdadm, which was
unexpectedly difficult to remove.
You cannot have mdadm and dmraid co-exist, unless the mdadm partitions
and the dmraid array are on separate drives. YOu can only have one or
the other.
So if you have WIndows sitting on fakeraid/dmraid array, you install
Ubuntu using the laternate CD, and when it asks for you to activate the
SATA
Just to reiterate, I achieved the desired results described in the
original bug after extensive research, trial and error before i filed
the bug.
"To get rid of dmraid you just don't install it. The live cd doesn't
have the dmraid package preloaded"
Ok. But that's not at issue. The alternate i
