> Have you ever had pid 1 (systemd or any other init) crash? For the last ~three years I've been paid to maintain high reliability algorithmic trading systems that ran systemd and a whole lot of other stuff, and systemd has never crashed on me.
You see, that's the argument I hear a lot from Systemd advocates. The problem with anecdotal evidence is obvious. When you hear people opposing Systemd, practically all of them have some real-life issues with it, often related to functionality that would otherwise be non-essential (i.e. doesn't really need to be handled by PID 1). Of course if you don't have a particular problem, you don't feel it's important. That's precisely the attitude people resent.

Yes, but a lot of people have real-life issues with it on their desktop of the form "It's too complicated." I'm asking specifically about real-life issues on production servers at scale. There will of course be tools that are poorly suited for a personal machine (even a personal server) but well suited for a team that wants to run a bunch of reliable servers.
For instance I would never be happy running RHEL on my desktop, but that doesn't mean RHEL is useless.
I can't quote any statistics but have the impression that a large part of non-Systemd crowd are old-time admins who maintain a large number of servers, myself included. When you break something on a desktop machine, that's easily fixable. When you need to deal with a large heterogeneous environment, you prefer to have things handled a bit more gracefully. Linus is a good example of a person who got this right.
