podman: "podman pod create --infra --infra-image" does not execute entrypoint of the infra-image

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

In openSUSE land we want to establish our own pause container, and because we have a nice structured way of building and testing containers, we want to use it for our new pause container.

This means that we have a prototype pause rpm package hosted at https://build.opensuse.org/package/view_file/home:favogt:kubix-images/kubic-pause/kubic-pause.spec?expand=1

With a prototype pause container definition at https://build.opensuse.org/package/view_file/home:favogt:kubix-images/kubic-pause-image/config.kiwi?expand=1

coming together to produce registry.opensuse.org/home/favogt/kubix-images/tw/kubic/pause:0.9

As you can see in the .kiwi link, the OCI container has a defined entry-point of /usr/bin/kubic-pause

However podman pod create --infra --infra-image registry.opensuse.org/home/favogt/kubix-images/tw/kubic/pause:0.9 produces the following error

error starting Infra Container: container create failed: container_linux.go:344: starting container process caused "exec: \"/pause\": stat /pause: no such file or directory"
: internal libpod error

In short, it seems podman is trying to call /pause and ignoring the entrypoint of my --infra container. I think this is a bug.

Steps to reproduce the issue:

1. Use podman pod create --infra --infra-image with an OCI image with an entrypoint other than /pause

Describe the results you expected:

Podman should honour the entrypoint defined in it’s infra containers
