[DEPRECATION WARNING]: Invoking "dnf" only once while using a loop via squash_actions is deprecated. Instead of using a loop to supply
multiple items and specifying `pkg: "{{ item }}"`, please use `pkg: ['ntpdate', 'libselinux-python']` and remove the loop. This feature
will be removed in version 2.11. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
