Ditto. my personal experience with systemd has been "wow, it's easier than ever to write an init script that runs when it's needed".
Looking at the components that make up a modern UNIX system, it's definitely time to think "how can we make a new operating system, evolved from UNIX, but with a more coherent core running the majority of run time orchestration".
Similar opinion here. I put it off for when I could learn it better, and so far it's been fine... sometimes nice too when it has a feature I want that's already built-in (depending on version level and all that).
