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__.

Move the opensuse utilities to the zypper element so they can be used by
SUSE or zypper based elements. This brings the zypper element somewhat
in line with the rest of the package manager elements.

The various distro elements include a copy of this script which installs
all files in the bin/ dir of the copied element hooks in to
/usr/local/bin. Lets share code rather than repeating ourselves.

Updates additional elements in diskimage-builder to use the declarative
package install support provided by the package-installs element.
package-installs does not yet support the pkg-map functionality, so
elements using pkg-map are not migrated. That support will come in the
near future.

This provides some customizations for zypper based distributions (e.g.
openSUSE and SLES). It is heavily inspired by the yum element and sets up
zypper to cache downloaded package outside of the chroot so that they can be
reused to speed up subsequent builds.

This is currently experimental/incomplete. See
elements/opensuse/README.md for details.
