Ask HN: What does is the function of systemd?
Seems topical.
I don't know half the terminology in the wikipedia article, and, in light of recent events, it seems worthwhile to know.

Init systems are traditionally the first thing that is executed when the kernel boots and passes control to userspace. They're responsible for starting all the services that are configured/enabled.
In addition to this "basic" functionality systemd has extras which allow it to handle dependencies, start services on-demand, and handle logging, etc.
Beyond that you'd be best reading the documentation on the systemd site - I've never used it, but the basics don't seem too hard to understand.
