That's correct. Our pm isn't broken. Basically we do

make DESTDIR=/some/staging/tree install

Then we can process the image in /some/staging/tree before it is
actually installed to the live fs.

Everyone else gets this right because you don't normally have to go into
the image and trash most of it to get what you need.

Great analogy. I understand that binary package maintainers can do this
very easily, but it doesn't work that way on a source based distro.
What we are being asked to do is very inefficient imo, and it isn't
 because of our package manager.

WRT migrating to systemd: I am just a package maintainer. I am not in a
position where I can tell our distro that we must do that, and knowing
what I know about our distro, I'm pretty sure that migrating to systemd
isn't going to happen at this point.

Something needs to be done, because there are clearly people across
multiple distros who need a udev only build for whatever reason.
