Jiri Stransky 1e9cf3a1c8 Remove deprecated overriding of cloud-init defaults The "set to localhost by default" behavior for manage_etc_hosts has been deprecated for more than a year now by change Ia8582883f737548e2911d3f36a1943e5b236281b. Setting that value to "localhost" is still possible, but it won't be the default anymore. If the previous behavior of assigning the hostname and FQDN to 127.0.0.1 is still desired in some environments, it can be achieved by setting the DIB_CLOUD_INIT_ETC_HOSTS environment variable, as the deprecation warning message suggested.

base
====
This is the base element.

Almost all users will want to include this in their disk image build,
as it includes a lot of useful functionality.

The `DIB_CLOUD_INIT_ETC_HOSTS` environment variable can be used to
customize cloud-init's management of `/etc/hosts`:

 * If the variable is set to something, write that value as
   cloud-init's manage_etc_hosts.

 * If the variable is set to an empty string, don't create
   manage_etc_hosts setting (cloud-init will use its default value).

 * If the variable is not set, use "localhost" for now. Later, not
   setting the variable will mean using cloud-init's default. (To
   preserve diskimage-builder's current default behavior in the
   future, set the variable to "localhost" explicitly.)

Notes:

 * If you are getting warnings during the build about your locale
   being missing, consider installing/generating the relevant locale.
   This may be as simple as having language-pack-XX installed in the
   pre-install stage

 * This element ensures /tmp/ccache will be available in the chroot
   during the root, extra-data, pre-install, install and post-install
   stages.  /tmp/ccache is unavailable during block-device, finalise
   and cleanup stages as it will have been automatically unmounted
   by then.
