Currently there is no description of dependencies in the generated documentation of the elements: therefore a user of an element does not know which other elements are automatically included and e.g. which configuration options are available. In addition there are some copy&pastes of parts of the README.rst scattered thought different Ubuntu and Debian specific elements. This patch adds a semi-automatic generation of dependency information of all elements. Nevertheless these are not automatically included. The author of the element's README.rst can decide if and where the dependency information should appear and can use the descriptor .. element_deps:: for this. This patch adds the dependency information for some Debian and Ubuntu patches - and creates the base for later removing the duplicated parts. A call is added to element_dependencies._find_all_elements() to populate reverse dependencies for Element objects. (This is a reworking of I31d2b6050b6c46fefe37378698e9a330025db430 for the feature/v2 branch) Change-Id: Iebb83916fed71565071246baa550849eef40560b

Provide dpkg specific image building glue.
|
|
|
|
The ubuntu element needs customisations at the start and end of the image build
|
|
process that do not apply to RPM distributions, such as using the host machine
|
|
HTTP proxy when installing packages. These customisations live here, where they
|
|
can be used by any dpkg based element.
|
|
|
|
The dpkg specific version of install-packages is also kept here.

Environment Variables
|
|
---------------------
|
|
|
|
DIB_APT_KEYS
|
|
:Required: No
|
|
:Default: None
|
|
:Description: If an extra or updated apt key is needed then define
|
|
``DIB_ADD_APT_KEYS`` with the path to a folder. Any key files inside will be
|
|
added to the key ring before any apt-get commands take place.
|
|
:Example: ``DIB_APT_KEYS=/etc/apt/trusted.gpg.d``
|
|
|
|
DIB_APT_LOCAL_CACHE
|
|
:Required: No
|
|
:Default: 1
|
|
:Description: By default the ``$DIB_IMAGE_CACHE/apt/$DISTRO_NAME`` directory is
|
|
mounted in ``/var/cache/apt/archives`` to cache the .deb files downloaded
|
|
during the image creation. Use this variable if you wish to disable the
|
|
internal cache of the ``/var/cache/apt/archives`` directory
|
|
:Example: ``DIB_APT_LOCAL_CACHE=0`` will disable internal caching.
|
|
|
|
DIB_DISABLE_APT_CLEANUP
|
|
:Required: No
|
|
:Default: 0
|
|
:Description: At the end of a dib run we clean the apt cache to keep the image
|
|
size as small as possible. Use this variable to prevent cleaning the apt cache
|
|
at the end of a dib run.
|
|
:Example: ``DIB_DISABLE_APT_CLEANUP=1`` will disable cleanup.
