yes, for now at least it does. Because if that is set, we expect that every image is pulled using the partial pull code path, so that we can enforce composefs.

... to centralize the fallback allowed / required logic. Should not change behavior, apart from maybe some error text. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
Instead of sharing the badRequestErr logic, duplicate it. That's a bit ugly, but we get better debug messages and a more traditional control flow. Should not change behavior, except for debug messages. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
Use switch to handle the various TOC presence cases Signed-off-by: Miloslav Trmač <mitr@redhat.com>

First refactor the logic a bit, to separate “are partial pulls allowed” from “set up partial pulls”.
See individual commits.
@giuseppe RFC on the logic, WRT composefs integrity enforcement.
Currently untested, that’s going to happen in containers/podman#24287 .
