Per conversation with @pbrobinson and @siosm , the IoT compose is producing or is going to produce a container image we want to get published to registries ASAP.

We agreed the easiest way to get this done in the short term is to extend or copy-and-modify the existing https://pagure.io/releng/blob/main/f/scripts/sync-latest-container-base-image.sh script that does this job for container images in the main Fedora compose. The extended or modified script can be called from https://pagure.io/fedora-iot/pungi-iot/blob/main/f/nightly.sh , just like we call the current script from https://pagure.io/pungi-fedora/blob/main/f/nightly.sh . I guess it's up to you whether you want to handle this across branches or only for Rawhide for now.

The box the script runs on will need to have the appropriate credentials to publish things to whatever registry/registries it wants to push to, which may need help from @kevin .
