MetaSchema�get_meta_doc)�
PER_ALWAYSa���This module will update the contents of the local hosts database (hosts file;
usually ``/etc/hosts``) based on the hostname/fqdn specified in config.
Management of the hosts file is controlled using ``manage_etc_hosts``. If this
is set to false, cloud-init will not manage the hosts file at all. This is the
default behavior.

If set to ``true``, cloud-init will generate the hosts file
using the template located in ``/etc/cloud/templates/hosts.tmpl``. In the
``/etc/cloud/templates/hosts.tmpl`` template, the strings ``$hostname`` and
``$fqdn`` will be replaced with the hostname and fqdn respectively.

If ``manage_etc_hosts`` is set to ``localhost``, then cloud-init will not
rewrite the hosts file entirely, but rather will ensure that a entry for the
fqdn with a distribution dependent ip is present (i.e. ``ping <hostname>`` will
ping ``127.0.0.1`` or ``127.0.1.1`` or other ip).

.. note::
    if ``manage_etc_hosts`` is set ``true``, the contents
    of the hosts file will be updated every boot. To make any changes to
    the hosts file persistent they must be made in
    ``/etc/cloud/templates/hosts.tmpl``

.. note::
    for instructions on specifying hostname and fqdn, see documentation for
    ``cc_set_hostname``
