Linux hosts using systemd 207 or later ignore ``/etc/sysctl.conf`` and only
    load from ``/etc/sysctl.d/*.conf``. This function will do the proper checks
    and return a default config file which will be valid for the Minion. Hosts
    running systemd >= 207 will use ``/etc/sysctl.d/99-salt.conf``.

    CLI Example:

    .. code-block:: bash

        salt -G 'kernel:Linux' sysctl.default_config

def default_config():
