[Podman] working with manifest lists

Hi, I'm trying to create a manifest list, so a multi arch image. I started by using skopeo to copy busybox:1.32 for two different architectures to my local container storage. I gave them locally different tags. After that I tried to create a manifest list using "podman manifest list". The first issue I noticed is that http://docs.podman.io/en/latest/markdown/podman-manifest-create.1.html shows a different syntax to what I get in podman 2.1.1 as I can not specify more then one image in the command. Anyhow, so I first create the list with the first image and then use "podman manifest add" to add the second image. Doing a "podman images" command I see that my manifest list image size increased a bit but is still just a few KB. pushing the manifest list now results in a failure. Should those commands work or am I missing something? I would also have expected that I can create the manifest list with skopeo, ideally as part of a copy call, but I didn't find anything on that in skopeo. Is there a better approach for combining multiple images to one? thanks, Hendrik
