SUMMARY

Podman has a "newer" pull policy: https://docs.podman.io/en/latest/markdown/podman-create.1.html#pull-policy which isn't supported by ansible-navigator (I tried).

It would allow to always keep the image actual while coping with bad network (or other challenges), especially important in Edge use cases, where connection isn't a given (or even if you just face the throttling introduced in the docker hub).

A timeout parameter might even be of advantage in case the network isn't completely broken but only too slow.
