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__. Change-Id: I5e3e3c97f385b1a4ff2031a161a55b231895df5b |

=== ilo === Ramdisk support for applying HP iLO firmware. The firmware files are copied in via an extra-data hook: the variable DIB\_ILO\_FIRMWARE\_PATH specifies a directory, and every file in that directory will be unpacked into a same-named directory in the ramdisk (using --unpack=...). If the path is not specified, a diagnostic is output but no error is triggered. During ramdisk init every found firmware installer will be executed using --silent --log=log The log is displayed after the firmware has executed. If the firmware exits with status 0 (ok), status 2 (same or older version) or 4 (ilo not detected) a diagnostic message is logged and init proceeds. Any other status code is treated as an error.
