> Not sure to fully understand. instead of modifying the host to add/remove the packages you want, you can create a docker image containing whatever you want to run (even if it's the docker daemon itself) then run that container using atomic tool with ostree/runc backend (without docker daemon)
the same way atomic host is running etcd and flanneld without docker daemon here is a session [root@laptop ~]# docker ps Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
