This has been a very interesting article to read. I can't help but see a glaring omission, and that is launchd. It's mentioned in several Poettering quotes in the article, but outside of that it gets two sentences in the entire thing despite obviously being heavily on Poettering's mind when coming up with systemd. It also came out right in the time period outlined in the article where there were several arguments over sysvinit boot times.
