The diagnostic is clear enough: usr-m: Conversion does not work on a union FS. : Your image will have to be rebuilt from a new FS tree, sorry. : Exiting. hier-convert is unable to fix all the non-top overlayfs layers from inside the container. Image-based systems are easiest to maintain in a top-down fashion: instead of upgrading packages inside the image and having the layer stack consume additional space, the base image is (hopefully reproducibly) regenerated on top of a repository snapshot. It's easiest to regenerate the image with filesystem 3 from the start and tag it as alt:sisyphus in the registry.
This is what I expect to be done...
