This is the main piece of functionality that's still missing: allocating
devices from preexisting VGs.

You can create and destroy lvm devices. You can reuse existing LVs,
optionally reformatting them. You can encrypt or decrypt them. What you
cannot do is allocate new LVs from old VGs. That's sort of the last item
on the TODO list.
