Except Ubuntu and Fedora each use their own container format. The entire reason we're in this place is that RedHat went with .rpm and Debian/Ubuntu with .deb. There's no-one winning in this format war, and no-one is winning by putting yet another layer of abstraction either. Like with Docker, the problem that container app images are trying to solve (that of incompatible 3rd party shared libs) cannot be solved by containers, because the reason for shared libs to exist in the first place is so that eg. security vulnerabilites in old shared lib versions can be transparently fixed by having the OS install newer libs; but (as you say yourself) with containerized apps this is impossible. You might as well ship statically linked apps instead.
