Hi Refractologists,
Following the ongoing systemd debate, I ended up with some diagrams (courtesy of Slavko) showing some dependencies on systemd.

He succeeded in modifying several of the key debian packages that propagate these dependencies by simply editing the packages' debian/ directories.
I've started to work on generating systemd-free packages for them, however my packaging-fu is a little (actually very) rusty.
If anyone is interested, I'll be happy to share the code and task! I think this is a better solution than pinning, although of course fundamentally imperfect.
Greetings,
