Applied, thanks! As quickly talked off-list: I pushed a follow-up commit to
change the warning to a notice for the case where only local LVM storages are
affected, as in that case a warning is IMO not justified, as keeping the status
quo then has no known problems, and while it might be a bit cleaner and save a
little bit of resources to not activate all local volumes on boot, it's not
worth the relatively scary warning level.
