Public bug reported: I don't have further details, other than this possibly being an artifact of attempting to switch to systemd about a month ago, and an attempt to switch back to upstart about a week ago. While I'm sure that's the problem with a few other packages, today was the first time I saw udev complain during a dist-upgrade.
