Overriding a list manifest image with another list manifest image is possible when the user has sufficient permissions to do so. In this process, only the list.manifest.json file is replaced, while the individual tags referenced previously in the original list.manifest.json continue to exist in the registry and remain accessible as standalone images. This behavior ensures that dependent systems can continue to pull specific tags directly, even after the list.manifest.json updates if they are pulled explicitly by their sha tag identifier. This characteristic is particularly important for maintaining system stability and enabling smooth transitions between different manifest versions.
