If I want to reinstall it, I can do so with rpm-ostree install cowsay and it will be added to the new image… but if I do that, I’ll have drift between my OCI image generated by CI/CD and the state of my virtual machine. This isn’t desirable because bootc delivers by default a bootc-fetch-apply-updates.service service that will periodically check if a new image is available and automatically switch to it to keep the system up to date (it’s a systemd timer that runs every 4 hours by default and will launch the bootc upgrade --apply --quiet command).
