Didn't you find though that systemd was just a black box? I was hoping to learn more about it as well- and I did manage to get a fully baked LFS CLI system up and running, and it was just like "ok install systemd..." and now... it just goes.

Sysv at least gave you a peak under the covers when you used it, and while it may have given people headaches and lacked some functionality, was IMHO simple to understand. Of course the entire spaghetti of scripts was hard to understand in terms of making sense of all the dependencies, but it felt a lot less like magic than systemd does.

I believe it's `systemctl list-unit-files` to see all the config that's executed, included by the distro, and then if you want to see the whole hierarchy `systemd-analyze dot | dot -Tpng -o stuff.png`

To me, seems much easier to understand what's actually going on, and one of the benefits of config as data rather than config as scripts.
