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__.

Now that we have moved onto neutron-dhcp-agent. dracut-network is no
longer needed, infact it was getting in the way. Dracut wasn't
requesting the classless-static-routes dhcp parameter but was
configuring networking. Removing this causes the network service to
redo dhcp and set the appropriate static route (specifically so
overcloud nodes are routed to the correct metadata server). This element
is still required for undercloud nodes so needs to be included there.

Installing redhat-lsb-core adds 87M to the install due
to bugzilla #1002342
lsb_release is a platform agnostic script, so this change fetches
a single file via source-repositories from linuxfoundation bzr http
and installs it to /usr/local/bin

Rather than dublicating code to implement rhel or any
other derivitive, this patch introduces an rpm-distro
element that should be used as a dependency.

The yum element provides for specific customizations
for yum based distros. The included customization is
a yum cache mounted outside of the chroot so that yum
downloaded packages are reused on subsequent image builds.

The dynamic kernel module system is not available on RHEL, CentOS,
Scientific Linux, or SUSE. Make it part of the distro post-install
rather then base post-install.

The fedora element downloads images too, so we should re-use the caching
code from the ubuntu element.
There doesn't seem to be other examples of code shared between root.d
scripts. In the fedora and dpkg elements we copy install-packages into
the chroot, but that model doesn't apply when we're running scripts
outside of the chroot. Seems sane to just run it directly from the bin/
dir in the temporary hooks directory.

This element will install the network modules for dracut and regenerate
the initramfs. The network support would allow us to configure the network
of the image via kernel cmdline instead of injecting files into the image.
