The /dev/.udev/db have been touched as well, which heavily implies that
udev was triggered.

With the rules being moved, it is possible that the trigger would reset
the permissions to 0660.

This is a pretty bad side-effect, so we should probably at least stop
the udev daemon on upgrade.

But this doesn't solve what's done it for you - as that's another bug.
I'd rather leave the symptom there for now otherwise we're hiding
something else.

Notably udev isn't in this list.
