        # The compatibility mode checks are also performed here in order to fetch the
        # Ansible version information only once.
        #
        # Current limitations:
        #   - The installation of a specific Ansible version is only supported by
        #     the "pip" install_mode. Note that "pip" installation also takes place
        #     via a default command. If pip needs to be installed differently then
        #     the command can be overwritten by supplying "pip_install_cmd" in the
        #     config settings.
        #   - There is no absolute guarantee that the automated installation will replace
        #     a previous Ansible installation (although it works fine in many cases)
