Correct, that's what I mean.

Hmm, interesting idea. On the one hand, we didn't do it for /lib. On the
other hand, it would probably save a lot of churn.

I think the lintian maintainers would have a preference here. If we do it,
I would prefer unconditionally, but they might prefer a new compat level.
I'm not sure if debhelper does look in /usr/lib/systemd/system. If not,
that needs to be fixed.

Right. Ideally, only for the transition period.

I believe doing systemd first is easier (it already has the logic for
Do you think doing both udev and systemd at the same time is better?
