Is it possible to add the --uts parameter to the molecule create playbook when using podman driver?

[Caseraw]

Is it possible to add below oneliner to the create.yml playbook, in the task "Create molecule instance(s)". It comes with the pip package molecule_podman?

Below oneliner can be placed between lines 153-173. In file ~/.local/lib/python3.10/site-packages/molecule_podman/playbooks/create.yml

{% if item.uts is defined %}--uts={{ item.uts }}{% endif %}

This allows to use the option uts in the molecule.yml, in the platforms array as part of an item. For example:

---
dependency:
  name: galaxy
driver:
  name: podman
platforms:
  - name: instance
    image: quay.io/centos/centos:stream8
    pre_build_image: true
    uts: private
provisioner:
  name: ansible
verifier:
  name: ansible

This fixes the following issue with current podman versions that do not allow setting the hostname of a container by default:

Error: invalid config provided: cannot set hostname when running in the host UTS namespace: invalid configuration

Had to change it manually in my containerfile for the podman container.
Thanks for the reference!
