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.)
The 'DIB_AVOID_PACKAGES_UPDATE' environment variable can be used to
avoid updating all packages, useful when wanting to avoid release
update.
* 'DIB_AVOID_PACKAGES_UPDATE' default is '0', all packages will be updated.
* set 'DIB_AVOID_PACKAGES_UPDATE' to '1' to avoid updating all packages.
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
