      We want to allow the relevant APIs to pin images and make sure those don't get garbage collected.

      Here is a summary of what will be required:

      1. CRI-O will need to be changed so that it doesn't remove pinned images, regardless of the version_file_persist setting.
      2. Add the new PinnedImageSet custom resource definition to the API.
      3. Initial proposal: #1609
      4. Add a new PinnedIMageSetController to the machine-config-controller.
      5. Add the logic to pin and pull the images to the machine-config-daemon.
      6. Update the documentation of recovery procedures to explain that pinned images shouldn't be removed.
