I like the idea behind ostree and bootc, but I feel that OCI (with tarlayers) is not a good fit. `repack` makes an absolute hash of things, and since the layers are logically packaged, they will have to be composed somehow, and then ostree becomes only slightly more useful than coreos's A/B usr.

OCI roughly assumes that layers will be laid out in some logical way, and that a given host will see opportunities to reuse across different instances, but with bootc, there will only ever be one instance.

OCI also assumes that individual layers are small enough that it is always worth pulling and unpacking a layer instead of some kind of authentication delta, which is great for a k8s cluster in a center, but not great for devices out on the edge, where you might want this kind of pseudo-immutable system even more.

I really want some standardized way for a manifest in OCI to say that "this content is also available in other format X here".
