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

Note: The ubuntu element is likely what you want unless you really know
|
|
you want this one for some reason. The ubuntu element gets a lot more testing
|
|
coverage and use.
|
|
|
|
Create a minimal image based on Ubuntu. We default to xenial but DIB_RELEASE
|
|
is mapped to any series of Ubuntu.
|
|
|
|
If necessary, a custom apt keyring and debootstrap script can be
|
|
supplied to the `debootstrap` command via `DIB_APT_KEYRING` and
|
|
`DIB_DEBIAN_DEBOOTSTRAP_SCRIPT` respectively. Both options require the
|
|
use of absolute rather than relative paths.
|
|
|
|
Use of this element will also require the tool 'debootstrap' to be
|
|
available on your system. It should be available on Ubuntu, Debian,
|
|
and Fedora.
|
|
|
|
The `DIB_OFFLINE` or more specific `DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE`
|
|
variables can be set to prefer the use of a pre-cached root filesystem
|
|
tarball.
|
|
|
|
The `DIB_DEBOOTSTRAP_EXTRA_ARGS` environment variable may be used to
|
|
pass extra arguments to the debootstrap command used to create the
|
|
base filesystem image. If --keyring is is used in `DIB_DEBOOTSTRAP_EXTRA_ARGS`,
|
|
it will override `DIB_APT_KEYRING` if that is used as well.
|
|
|
|
For further information about `DIB_DEBIAN_DEBOOTSTRAP_SCRIPT`,
|
|
`DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE` and `DIB_DEBOOTSTRAP_EXTRA_ARGS`
|
|
please consult "README.rst" of the debootstrap element.
