My patches fixed what I considered to be the 3 most fundamental
1) initramfs support for allowing a system's administrator to
optionally start the system even if the root RAID is degraded, (which
includes setting it in an /etc config file, setting it as a kernel
boot parameter, and choosing it interactively within a 15 second
2) mdadm debconf support for allowing the administrator to easily
configure this value (to boot degraded or not boot degraded)
3) grub support for installing the bootloader to each disk in a RAID

topic, see the lengthy set of user comments on my spec

Hmm, well, it will need to be at least Alpha4. The newer, the better
though. I just returned from vacation and I will spend some time
testing this from the installer images next week. Thanks.
