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.
