while this writeup is really cool I'm still asking myself as a sysadmin if all the complexity in the wider systemd ecosystem is a requirement to solve modern requirements or if it would be possible to have an reactive event based system that's easier to debug/introspect. Despite working on Linux systems for more than 10 years I wouldn't be able to debug such an issue like the author did in the article and I doubt most other sysadmin have the time and patience and knowledge to deep dive into the system for debugging something that shouldn't be a problem in the first place... That beeing said is there a good a writeup / deep dive into systemd concepts? Really cool would be something like a book - the official docs are quite spread out and it's either rather simple high-level stuff or basically: read the source.
