Comment 1 Hans de Goede 2009-03-13 08:56:49 UTC 
Ok,

So the problem is that *before* we start scanning disks and activating stuff like existing lvm's / dmraid sets, you already have dm-0 and dm-1 device mapper devices.

Do you know what they are / where they've come from ? Usually all the device
mapper devices are made by us, so we know what they are. Now we are somehow misidentifying them as disks.

Luke,

The rawhide image you are referring to, that wouldn't by any chance be a livecd
image would it ?

I think this is caused by us not recognizing LV's as LV's on livecd's, which
would mean this is a dup of 489427.

No sooner had I put this bug in needinfo than I found another one with the same problem.  Duping...

Yes, this was on a livecd.
