we could not validate that running instances come back after a reboot. the best we’ve got is a come back after killing and starting the docker daemon again.
you can now operate your Docker host
systemctl restart docker.socket
systemctl restart docker.service
systemctl status docker.socket
systemctl status docker.service
systemctl stop docker.service
systemctl stop docker.socket
as user
docker images -a docker ps -a docker pull pbraun9/devuan docker pull pbraun9/devuan-svr4
