Docker and the OCI container ecosystem

This is an area of interest to me - the containers/storage and containers/image libraries used to contain at least some level of ostree support, but I know at least part of that was removed due to nobody using it or being willing to maintain it. I've seen other parts of it that have gotten some work at least semi-recently, though; I haven't yet explored what is currently possible there.

Podman supports <a href="https://www.redhat.com/sysadmin/image-stores-podman">additional image stores</a> - I've experimented with using this feature to store image stores in ostree repositories and then get delta updates instead of having to pull whole layers at once.

I know Balena has some sort of delta update technology for their container runtime but I'm unclear how it works.There are also things like <a href="https://github.com/containerd/stargz-snapshotter">stargz</a> (usable with containerd/nerdctrl) that do interesting things with how images are transferred over the network.
