There's some cheating/sloppiness going on here, with the same tag
and sometimes same needle being used to match "LVM2 Volume Group"
and "LVM2 Logical Volume". Today this caused us to pick the thin
pool entry instead in a test, so let's just clean this up and do
it right, with separate needles for matching each thing.
