You're probably right - I didn't figure that out (I vaguely recall some dh_thing commands but I've fortunately reclaimed most neurons involved with it). It also turns out that the only thing we did want to do was copy files onto the filesystem - early on we had some more complex bits like pre and post install scripts, and they got us into a horrible mess via not being written sufficiently defensively and apt giving you basically no safety rail and being very unhelpful at getting you out of a bad situation. After that we banned anything that wasn't just "put files on system".
