I've been repeatedly burned by systemd, both on machines I've administered and on appliances. In every situation, the right fix was either "switch distros" or "burn developer-months of work in a fire drill".
In fact, I just decided to go with FreeBSD instead of proxmox specifically because proxmox requires systemd. The last N systemd machines I've had the misfortune to touch were broken due to various systemd related issues. (For large values of N.)
I assume that means anything built on top of it is flaky + not stable enough for production use.
