.Using the RHEL system role with Ansible 2.9 can display a warning about using `dnf` with the `command` module Since RHEL 8.8, the RHEL system roles no longer use the `warn` parameter in with the `dnf` module because this parameter was removed in Ansible Core 2.14. However, if you use the latest `rhel-system-roles` package still with Ansible 2.9 and a role installs a package, one of the following warnings can be displayed: ---- [WARNING]: Consider using the dnf module rather than running 'dnf'. If you need to use command because dnf is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message. ---- ---- [WARNING]: Consider using the yum, dnf or zypper module rather than running 'rpm'. If you need to use command because yum, dnf or zypper is insufficient you can add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message. ---- If you want to hide these warnings, add the `command_warnings = False` setting to the `[Defaults]` section of the `ansible.cfg` file. However, note that this setting disables all warnings in Ansible.
