Let's add a very simple mechanism for doing A/B updating of disk images: for root + /usr and their verity partitions let's ue strverscmp() on the label to determine which one to use when dissecting a disk image. That way, if the root partition label contains a string such as "foo-0.15" and another one "foo-0.16", the latter wins. For other partition types let's stick to the logic of "first partition found" win, as before. Versioning makes sense for partitions that typically and primarily may carry software packages, but the other partition types usuall don't.
