This bug as actually been fixed in 228-3 by

https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?id=ea089f29bbd2583545b5c1a83756feafacf2801f

We can't unfortunately fix the existing udev.prerm of older versions,
only make sure the new one no longer has the problem.

I wonder if this will affect dist-upgrades from jessie.
Maybe we should drop the Breaks from ifupdown and only use Replaces there.

This is not entirely correct and can lead to missing files on package
downgrades, but it seems to me that this is the lesser evil than having
a failed (dist)upgrade.
