Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.

If element-info fails we do not detect it due to it being run in a
subshell. Whenever this happens it is a terminal error (theres no way we
can run without an expanded set of elements) so lets detect and fail
early.

Currently, this is a noop, since diskimage-builder currently uses
tests/install_test_deps.sh to manage OS dependencies. The next patch
in the series, will complete the migration to bindep.

Recommended packages are usually useful but we normally don't need
them in order to have a working system. As a result, avoid pulling
them in when doing a regular package installation or a distribution
update. Extra packages can be pulled in using the usual '-p' parameter
or from within the elements that actually need them. The results of
this change are quite significant, resulting to gains from a few dozen
of MBs up to a few hundred depending on the selected elements.

When debugging, this is very noisy for very little value. If we need
to specifically debug this script we can turn up the level.

cloud-init-local needs to be run in the boot runlevel because it
modifies services in the default runlevel. When a runlevel is started
it is cached, so modifications that happen to the current runlevel while
you are in it are not acted upon.

We currently have 'user guide' and 'developer documentation'. Lets
rename to 'developer guide' for consistency.

By default sphinx uses localtoc which means 'show TOC for this page'.
Using a global table of contents on the sidebar is much more user
friendly wih our docs structure.
Change-Id: I215732d3848b4b75d9171bdbaaf2ff2e4dcc01f0
The table of contents for our developer guide does not show due to the
fact that it is past the first sub-header.

Releasenote translation publishing is being prepared. 'locale_dirs'
needs to be defined in conf.py to generate translated version of the
release notes.
Note that this repository might not get translated release notes - or
no translations at all - but we add the entry here nevertheless to
prepare for it.
