It seems like the coolest part of this isn't the systemd part necessarily (unless you're a systemd fan). It's that the combination of Quadlets + coreos gives:

- Node starts up with a container daemonized

- Automated updates of the registry image

- A nice single arg to pass to your cloud provider CLI userdata that launches the OS + container (vultr-cli in this case)

I guess you can do something similar with any linux userdata but the script wont be as clean. Has anyone built something lite to launch docker containers on boot in ubuntu (this is particularly helpful for cloud provider CLIs) without writing the whole script manually? Something nicer than `apt update && apt install -y docker && docker run --rm --restart-always ...` that includes the registry autoupdate.
