Bug Description
On a debian etch machine, we have 3 MD Raid devices. The root is a RAID 1 device atop an lvm. It got messed up and needed rescuing. Using the Ubuntu server CD in rescue mode was great but with one minor problem.
Although the rescue system detected all three MD arrays and assembled them without me even asking, when the system prompted to choose a partition to mount as root, only the physical devices (/dev/sda1, /dev/sda2, /dev/sdb1, /dev/sdb2, ...) were available. This meant you couldn't mount the raid array as root (which it should have been).
Instead I switched to a command line, mounted it by hand under /mnt off the initrd, did what I needed to and rebooted, but it would have been much cleaner if /dev/md* were available to mount as root fs and I'm sure that is probably the intention. LVM was not in use on the root in this case, though I guess LVM devices should be made available too.

Uh, I meant to point at the upstream debian installer, not the linux kernel. Launchpad is a confusing beast.
