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__.

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.

Add a new opensuse-minimal element to build small and highly
configurable openSUSE based images using the zypper-minimal element
as the main building mechanism
Change-Id: Iebfc4ad4aff763e511b093f1607b55851ccbddcb
All SUSE-based elements can benefit from the mkinitrd phase to move it
to a more generic location.
Change-Id: Ife171d462a393b6ac0bf2c5eaa48ea25eaf4d1cc
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.

There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

disk-image-create processes a DIB_IMAGE_CACHE variable and exports it,
but there are several elements that ignore the value and wrote out
the base location themselves. Use the variable everywhere so that it
will get overridden everywhere.

Ensure cache mount directory exists before its used. The zypper element
would error when attempting to mount the cache directory because the
mount point did not exist. This patch corrects that.

Scripts in pre-install.d run as root so there is no need to sudo commands.
This patch also helps avoid an error when sudo is not installed in the
default image.

As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later. Setting this on all existing scripts
will allow us to enforce use via Jenkins.

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.
