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__.

In order to avoid conflict with installing dependencies for IPA from
pypi and distribution packages this patch propose installing IPA in a
virtual environment.

I recently built a ramdisk for IPA and was confused by
the fact that the source-repositories name did not
match the element name. (this is a convention,
confusing when they don't match but certainly not
required).
This patch makes it so you can use DIB_REPOREF_ironic_agent to
customize the IPA ramdisk sources when building ramdisks.
For backwards compat if DIB_REPOREF_agent is set it automatically
sets the new DIB_REPOREF_ironic_agent to that value as well.

In Kilo, we added added an iscsi extension in
ironic-python-agent which requires tgtd and tgtadm.
This commit adds scsi-target-utils to the ramdisk for
this.
Also the git protocol for retrieving the source code is
changed to http. Git protocol doesn't go through a proxy,
but http can.

This element creates kernel and ramdisk files based on Fedora,
example:
disk-image-create -a i386 -o test fedora ironic-agent disable-selinux
