    # Pushing images based on PRs to the main repository should be prevented from
    # a security point of view.
    # Pushing images for PRs to ttl.sh might make some sense but for that we would need
    # to distinguish between the possible triggers. Until we do so, we therefore
    # disable the building and pushing of PR based images to GHCR.
