# io.containers.autoupdate label will instruct podman to reach out to the
# corresponding registry to check if the image has been updated. If an image
# must be updated, Podman pulls it down and restarts the systemd unit executing
# the container. See podman-auto-update(1) for more details, or
# https://docs.podman.io/en/latest/markdown/podman-auto-update.1.html
