Instance is left in the stopped state and one has to manually start it.

[tailhook]

Well, this was intentional. You are expected to run start --foreground when start-conf=manual. And also we couldn't start edgedb in any other way when we supported systemd only. So I'm not sure yet if we want to change this.

But it should print instructions instead of just spitting the error log.
