Container created through the Compat API does not inherit /etc/hosts entries, but it can still resolve them

First of all, the title above just explains an observation and not an actual problem.

I have noticed that after I switched to podman v5, the host entries from /etc/hosts are no longer present on the
containers created through the Compat API. Although it can still resolve those entries.

I could not find any spec change from 4.x to 5.x to handle this through the Compat API ContainerCreate operation.

Here is a small reproducer (along with a sample request message).
You need to tweak the socket endpoint before trying it:

podman rm -f my-container
podman pull quay.io/fedora/fedora:41
curl -v --unix-socket /run/user/1000/podman/podman.sock \
    -X POST \
    -H "Content-Type: application/json" \
    --data-binary '{"Image":"quay.io/fedora/fedora:41","Cmd": ["tail", "-f", "/dev/null"], "Name":"my-container"}' \
    http:/d/containers/create?name=my-container
podman start my-container
podman exec my-container cat /etc/hosts

Is it a problem (not to see those entries) or not? And does anyone know if it is possible to have the host entries listed?

Thank you.
