If ``preserve_hostname`` is set, then the hostname will not be altered. A hostname and FQDN can be provided by specifying a full domain name under the ``FQDN`` key. Alternatively, a hostname can be specified using the ``hostname`` key, and the FQDN of the cloud will be used. If a FQDN specified with the ``hostname`` key, it will be handled properly, although it is better to use the ``fqdn`` config key. If both ``fqdn`` and ``hostname`` are set, the ``prefer_fqdn_over_hostname`` will force the use of FQDN in all distros when true, and when false it will force the short hostname. Otherwise, the hostname to use is distro-dependent. .. note:: cloud-init performs no hostname input validation before sending the hostname to distro-specific tools, and most tools will not accept a trailing dot on the FQDN. This module will run in the init-local stage before networking is configured if the hostname is set by metadata or user data on the local system. This will occur on datasources like nocloud and ovf where metadata and user data are available locally. This ensures that the desired hostname is applied before any DHCP requests are performed on these platforms where dynamic DNS is based on initial hostname.
