podman cp support missing?

[duck-rh]

Quack,

I've been giving a try to crun-vm to overcome problems we have with nested containers (CI container running molecule tests) and we use an image based on quay.io/podman/upstream, only adding systemd needed for certain tests.

It seems the image is compatible with crun-vm as it creates it properly (with podman run) but the gitlab preparation script needs to copy the gitlab-runner into the VM before exec-ing the real workload and that fails:

More precisely this command fails: podman cp --pause=false "${RUNNER_BINARY}" "$CONTAINER_ID":/usr/bin/gitlab-runner

Did I make a mistake or is the cp command not supported yet?

Regards.
