The problem is that vgscan wants to recursively remove /dev/vg00 and
its contents but mishandles the case that /dev/vg00 does not even
exist anymore (since after a reboot a devfs is 'clean').

This is easy to fix, I'm attaching a patch.
Would the lvmtools maintainer consider this patch for inclusion into
the tree?
