Recent changes in project-config have shown that we leave the system
in an inconsistent state when installing from source. On fedora, we
will have installed the python2 packages, but then used $DIB_PYTHON to
install python3 pip from source!
This tries to clarify the situation. As described in the document,
with package installs, we just install the $DIB_PYTHON packaged
versions.
Source installs want to take over the global namespace. This is the
price you pay for running the latest versions outside package managers
:) The only sane thing seems to be for us to normalise python2 &
python3 versions of pip, setuptools and virtualenv and then hacking
things such that "/usr/bin/pip" and "/usr/bin/virtalenv" remain
defaulted to python2 versions.
Documentation is added

Currently we install pip/virtualenv with "/usr/local/bin/dib-python".
This means that every time you create a virtualenv, the python
interpreter inside it is called "dib-python" which is confusing.
Add an env var DIB_PYTHON that points directly the to interpreter
available during build, for use when running scripts.

This change move "do_extra_package_install" from pre-install to install
phase.
Extra packages are added by user request using the flag "-p", This
package should not be something the elements depend on.
The reason behind this patch is to move the extra package install to
a proper phase, Also more reasonable if base element run package update
to be before we install extra packages.

The current output for package-installs-v2 is inscrutable [1]
The problem starts with process_output() which is not capturing
stderr. This means that any stderr output is dislocated from any
stdout output around it. This is *really* confusing as you get a
bunch of seemingly meaningless stderr output from any calls before you
see any stdout (e.g. in [1] you can see random yum error output that
should have been with the yum call)). The simplest thing to do is to
redirect stderr to stdout which keeps everything in sync.
This causes a slight problem, however, because pkg-map outputs both
status information and errors on stderr. To work around this but
maintain compatibility, we add a "--prefix" argument that prepends
mapped packages from pkg-map with a value we can match on. The
existing status/debug output from pkg-map is low-value; modify the
call so that it will be traced only at higher debug levels (e.g. -x
-x).
The current loop is also calling pkg-map for every package in every
element (this is why in [1] the same message is repeated over and
over). This is unnecessary; it only needs to pkg-map once for each
element, giving the package list as the arguments. Create package
lists by element and pass those to pkg-map.
As a cleanup, there is no point in printing e.output if the
process_output fails for the install because we are already tracing
it; i.e. the output, even for failures, is already in the logs.
Printing it again just duplicates the output.
[2] is an extract showing what I feel is a much more understandable
log output for a fairly complex install.

DIB_PYTHON_EXEC was added in I5fab0e192c3a2dad8f60e821c184479e24e33bcd
to export the python that disk-image-create is running under. If dib
is installed with python3 then just calls "python" (python2) to run
sub-scripts, it fails to find itself.
This has been tested in devstack gates that use py3x

The dib-run-parts element was copying our internal version of
dib-run-parts into /usr/local/bin to be used running scripts inside
the target chroot. However, it never cleaned up after itself. This
means all images were left with an unmanaged local install of
dib-run-parts.
This copies dib-run-parts into the hooks directory of the chroot and
runs it from there. It is cleaned up automatically on the exit path.
The dib-run-parts element is no longer required and it has been
removed from all dependencies. It is left with a deprecation notice
in the README. For compatability we convert it to simply install
dib-utils.
Codesearch shows no users depending on this unintentional implicit
install. Note os-refresh-config depends on dib-utils and thus will
have an explicitly installed version.

It was an oversight during v2 development for dib to start providing
dib-run-parts. The intention was for dib to use a vendored
dib-run-parts directly from $_LIB and have no dependencies on
dib-utils at all. By exporting dib-run-parts, we created an
unintentional conflict with the dib-utils package which provides the
same script.
Tools that depend on dib-utils are unaffected by this
(os-refresh-config).
The only tool that installs diskimage-builder and then assumes
dib-run-parts is available in the path is instack. I have proposed
Ibfe972208df40fa092b11b5419043524c903f1b4 to modify that to use our
internal version.

Add DIB_EPEL_DISABLED flag that allows installation of the EPEL repo,
but to have it disabled by default. This will help when you have
unavoidable EPEL dependencies, but want to make sure you only pull
specific things in with "--enablerepo" calls when installing those
packages.

zypper on non-suse hosts is not parsing the pattern repodata because
those are marked as an inofficial extension to the repomd specification.
This is not a big issue as there is meanwhile in newer openSUSE
distributions a pattern *package* that depends on the same packages like
the pattern would do, so we can just replace it with that.

When a glean is running on centos with multiple NICs, it will try to
systemctl enable network.service multiple times for each interface.
Because of systemd magic, it is possible for the systemctl command to
fail in a race condition.
glean shouldn't be enabling network.service during boot in
pre-networking phases (Ib2b618dd975ca44e9c6b0a2c9027642ffc46b9b0). I
have proposed I8319f1ed6498a9d447950c2b4b34bca59e7b97e4 to remove this

diskimage-builder usually provides defaults that work out of the box.
One default that does not work outside of x86 land is Ubuntu distro
mirror url. Considering there are only two valid default options, we can
automatically choose a better default.
This patch changes behavior only for architectures known to be using
http://ports.ubuntu.com/ubuntu-ports. All others still would use
http://archive.ubuntu.com/ubuntu as default. It provides some guarantee
that we do not introduce a regression.

We somewhat discussed skipping qcow2 generation previously in
I9372e195913798a851c96e62eee89029e067baa1. As recent issues with PPC
testing have shown, we are not actually testing the "vm" element and
hence the bootloader path in the functional tests.
I don't think we need to test this on every element; it overlaps
somewhat with the testing done by the nodepool jobs which build full
images and boot them. I also didn't want to introduce a separate run
for this. Thus it seems valuable to at least have one element
enhanced to do this installation and conversion in our default tests
for basic sanity.
This disables qcow generation by default, as per the other change, but
allows an element to drop a file that will override the output
formats. The Xenial element is modified to produce a qcow2 using
this, and also introduces a dependency on the "vm" element so it tries
to install the bootloader.
We now exit if the .qcow2 fails to build as well.

Prior to version 2.0.0 of diskimage-builder, the elements dir was hard
coded as 'elements' in dib-lint which allowed dib-lint to be consumed by
other projects (instack-undercloud). The 2.0.0 release has changed this
path and it is not overridable so that the other projects can still use
dib-lint. This change makes ELEMENTS_DIR and LIB_DIR check for an
existing environment variable so that dib-lint can be consumed outside
of the diskimage-builder project.
