nameserver information on your operating system, you do not want to use
this module. Many distros have moved away from manually editing ``resolv.conf``
so please verify that this is the preferred nameserver management method for
your distro before using this module.

Note that using :ref:`network_config` is preferred, rather than using this
module, when possible.

This module is intended to manage resolv.conf in environments where early
configuration of resolv.conf is necessary for further bootstrapping and/or
where configuration management such as puppet or chef own DNS configuration.

When using a :ref:`datasource_config_drive` and a RHEL-like system,
resolv.conf will also be managed automatically due to the available
information provided for DNS servers in the :ref:`network_config_v2` format.
For those that wish to have different settings, use this module.

In order for the ``resolv_conf`` section to be applied, ``manage_resolv_conf``
must be set ``true``.

.. note::
    For Red Hat with sysconfig, be sure to set PEERDNS=no for all DHCP
    enabled NICs.
