Comment 18 for bug 430542

Regarding RAID devices, I noticed just now that the /dev/md_dX names don't even exist any more on my system. They were definitely there before I upgraded from Jaunty to Karmic over the weekend.

See the "DEVICE NAMES" section of mdadm(8) for evidence that device file names of the form /dev/md_dNN do (did? should?) in fact exist.

My guess is that this is a "devmapper" issue, and not a "mountall" problem, but this is just a guess on my part.
