The more you tighten your grip

Seen at the webpage for RancherOS:

Everything in RancherOS is a Docker container. We accomplish this by launching two instances of Docker. One is what we call System Docker, the first process on the system. All other system services, like ntpd, syslog, and console, are running in Docker containers. System Docker replaces traditional init systems like systemd, and can be used to launch additional system services.
