yes exactly, it is under the rootless user+mount namespace.

You can use "podman unshare" to join the rootless user+mount namespace and see the overlay mount.

Thanks Giuseppe. That makes sense. So rootful containers run in the same default root "mount namespace" and that's why I can see the overlay mounts?

exactly. root can create mounts directly in the current mount namespace so it doesn't need to create a new one owned by a different user namespace. Giuseppe
