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.

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

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.

Depending on the types of deployment (security, nfv...) some extra
kernel flags are needed on the images. This change exposes the
DIB_BOOTLOADER_DEFAULT_CMDLINE parameter, defaulting to the
existing 'nofb nomodeset vga=normal', that will allow to modify
these boot params.

The order of the partitions is important, it needs to be preserved.
If using a simple dict, this is not happening. As a consequence,
checks like 'primary partition being first' are failing because the
dictionary sorts the partitions randomly.
Switched to OrderedDict solved the problem, as it preserves the
ordering it gets from the yaml blob.

Now that the main partitioning refactor patch is merged, there is

This patch moves the functionality from disk-image-create to the

original bash code in python.

Looks that the special handling for Ubuntu is not needed any longer
(its a pity that there are no detailed comments...).
The grub2 element is a second implementation of the bootstrap element
- but because there are some features that come only here, e.g. efi
boot, it should be working as long as this is not implemented in the
bootloader element.

Currently there is no description of dependencies in the generated
documentation of the elements: therefore a user of an element does not
know which other elements are automatically included and e.g. which
configuration options are available. In addition there are some
copy&pastes of parts of the README.rst scattered thought different
Ubuntu and Debian specific elements.
This patch adds a semi-automatic generation of dependency information
of all elements. Nevertheless these are not automatically included.
The author of the element's README.rst can decide if and where the
dependency information should appear and can use the descriptor
.. element_deps::
for this.
This patch adds the dependency information for some Debian and
Ubuntu patches - and creates the base for later removing the
duplicated parts.
A call is added to element_dependencies._find_all_elements() to
populate reverse dependencies for Element objects.

When merging feature/v2 we have re-enabled the centos-minimal test
which has a blank line in the element-deps. The modified get_elements
functions added in If97bcd21e45de1b5ed91023fdc441a4617051a6b were not
handling this.
Fixing this, we can extract this into some common code for
element-deps and element-provides.
Also, I noticed while debugging that the element list is an iterator
from reverse(), so printing it doesn't help. Fix up the debug output.

expand_dependencies() was a public interface so we should try and
preserve backwards compat. However, since the interface is really
broken, add a new exported function "get_elements" that instack can
switch to. This returns the canonical list of elements without
duplicates, and gives the path to each element too.
This highlighted that the unit tests were really a bit wrong. They're
testing inner functions when we have an "API" in the get_elements()
function. Convert all unit-tests to use this function instead. Since
this is a library call, convert the sys.exit() calls to raised
exceptions.
Refactor the variable output into a separate function so we can do a
sanity check on it.
The added flake8 ignores are for the "over-indented for ... indent"
which happens a lot with these new longer lines. Most other projects
ignore them.
This is an alternative proposal to

Because we're still fundamentally a python program calling a
shell-script, there's some oddities like not having the virtualenv
bin/ in the $PATH if we call disk-image-create directly.
We can detect this, however, and activate the virtualenv before we
fork the disk-image-create shell script so everything "just works".

Move dib-run-parts from dib-utils into diskimage-builder directly.
For calling outside the chroot, we provide a standard entry-point
script. However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element. I believe this to be the KISS approach.
This removes the dependency on dib-utils. We have discussed this
previously and nobody seemed to think retiring dib-utils was going to
be an issue.
This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

It has always been a weird thing that dib is a python package, but
is totally driven by the disk-image-create script. It creates this
strange division that is hard to explain.
This moves disk-image-create to a regular python entry-point
Currently, this simply exec()s the original disk-image-create script.
However, we now have a (private) interface between disk-image-create
written in python and the driver shell script. Here's some things we
could do, for example:
* Argument parsing is generally nicer in Python, and then end result
is mostly just setting environment variables to flag different things
in the shell script. I could see us moving the argument-parsing into
diskimage_builder.disk_image_create:main() and just setting things in
os.environ before the exec()).
* I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in
disk-image-create by calling-back to element-info. We can just call
element_dependencies.find_all_elements() in here an export is to
os.environ before disk-image-create starts.
* remove need for ramdisk-image-create symlink by just exporting
IS_RAMDISK based on sys.argv[1] value
* you could even unit test some of this :)
