> And running an init process like systemd as a top-level entrypoint was specifically discouraged. I spent years abusing docker to run images with systemd in them to test system configuration management tools running as many processes as you like. Once you hit it hard enough with a wrench you can make it do that just fine. Makes it very easy and extremely quick to test things in docker containers on your laptop which are meant to eventually wind up on VMs/metal. Horrible things like entire RHEL distros running systemd in one docker image... "I watched C-beams glitter in the dark near the Tannhäuser Gate..."
