Yea, i really thought that this stuff should be out of dockerland. Not that i dislike the feature, just that it seems to overlap with established tools that excel at doing one thing well.
FWIW, now that docker is handling the restart/monitoring it can actually do it better than if systemd is doing it, since docker knows that it doesn't have to tear down and re-create the network namespace, unmount/remount the container's FS, etc.
So when a container is restarted via the restart policy, it not only happens faster, it will get the same IP as well.
