It's not auto-starting the array on boot from smoke12 DVD. That would seem to be a \
problem, yet if it's a raid1 device, anaconda finds an already created LV and lets me \
use it, even though in a shell 'cat /proc/mdstat' shows no raid devices running, and \
pvscan, vgscan, lvscan see no pvs, vgs, or lvs. So the probing anaconda is doing \
seems to be separate from those tools - and I'm going to guess there may be a bug \
there when it comes to linear/concat raid during the scanning.

Some regression is in order it looks like.

The UI is confusing though, if you're expecting to manipulate either a VG or LV, in \
particular if you don't actually know what physical disks make up the VG. So what \
disks do I pick? Ahh, looks like I *must* pick all constituent physical disks. If I \
don't, then the Manual Partitioning window sees only a partition on the drive to be \
obliterated. It doesn't see the VG or LV.
