systemd muddled this considerably because it's not only an init system
project, it's an operating system plumbing project whose contributors
are very excited to fix what they view as a wide variety of historical
warts and suboptimal solutions to a ton of various low-level plumbing
and integration issues. This is simultaneously exciting and scary.
(And I'm going to go out on a limb here and say that if you find it
only exciting, or if you find it only scary, you are not thinking
enough about it, are missing significant components of this effort, and
should really think about it some more until you can recognize both
halves of that reaction and why they both make sense.)
