The format shared between the tools is an OCI image. Earlier you stated the images are incompatible, which is false. Then you switched to worrying about the internal representation of a container differing between the tools.
Why are you concerned about buildah’s internal representation of a container, unless you’re contributing to the codebase?
In all fairness, the blog is a bit confusing. I know that podman ad buildah both comply with the OCI image spec and that pod man in fact calls buildah. Which makes the various discussion around visibility etc. somewhat confusing to me. It may well be irrelevant in which case perhaps there’s a clearer way of explaining the relationship.
