I’m a GPU driver dev and you guys are talking ~alien~, right now. What does “daemonless” mean? Why is that good?

In Docker each container process is a child of the Docker daemon process. If you need to apply security patches to the Docker daemon it kills all your running containers.

Technically the parent process for a contained process with Docker is containerd-shim.
Also, Docker does support live restore if you want to keep containers running over daemon restarts https://docs.docker.com/config/containers/live-restore/
