"regular" seems to vary from distribution to distribution,

That may be the best bet.  Although it would be nice if it was smart
enough to throw away what it's already done.  If /dev/hda doesn't exist,
don't do any /dev/hda's.  And if /dev/hda is a full LVM drive, you may
as well not check partitions.  At this point, it's caused more problems
than majorly noted speed improvements, for me.

For now, I've created fifteen md and loop devices, even though I use 0.  I
suppose I could just remove them all...

It's either got to be ripped out, or made *really* smart.  At this
point, I think it's why vgscan is failing.  Which brings me to my next
point, it would be nice if vgscan would say something on partial volume
groups, ie: "only 9/20 drives found for volume group "vg00", leaving

I think this code is what caused vgscan to fail for me.  Going to try it
now that I've added all the device files...
