One time in an interview they asked how I felt about systemd. At first I thought it was a technical question, but quickly realized he was just probing to see if we'd get along.
I got a job offer that night.
I can totally understand the issues of unification there, and very much understand issues with poetterings perfectionist attitude to some issues. But do you know how much time I've spent on shitty, arcane, hand-crafted init-scripts?
Containers as a whole would be another great question there. I have a certain class of applications I wouldn't want to run without a container orchestration anymore after a certain scale. But on the other hand, I do have a bunch of systems I'd almost never want to run as containers for serious data.
It’s probably a little hard on those that don’t know. I’m not sure if they believe me when I say they aren’t expected to know.
Unfortunately, the question is quickly becoming dated. If you’re young and started with macOS and docker containers, you may never encounter it in your career. :)
I think overall this is a great question to sus out if someone is qualified for a role.
