The element builds dracut from source on Ubuntu because the
Ubuntu dracut package is broken and very old, so it can't be
installed properly and causes a number of other issues that
are fixed by using a newer version of Dracut.
This initial version should work in virtualized environments.
Further validation of its suitability for real baremetal
deployments will need to be done in the future, but this should
be sufficient to enable that work.
Regarding Dracut specifically, in order to limit the changes
needed in the existing scripts this element continues to use a
cut down version of the /init script that we were building for the
existing ramdisk. However, instead of running it as pid 0 it is
run as a Dracut pre-mount hook. This allows Dracut to set up all
of the hardware and system bits, while falling early enough in the
Dracut sequence to complete the deployment before Dracut would try
to boot off the hard disk.

Per [1], our current root label of cloudimg-root does not work with
XFS because XFS only allows 12 character labels. This change
addresses that by allowing a custom rootfs label to be specified
in the call to disk-image-create. There should be no backwards
compatibility concerns as the default label is unchanged. Any
external elements dealing with the label would need to be updated
to support this new feature, but should continue to work as before
as long as a custom label is not specified.

Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.
This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.

This patch adds exclusions for the indentation and newline
rules in dib-lint. The indentation exclusion is needed for
files using heredoc and wanting to preserve indentation.
The newline exclusion is added here for consisently treating
all dib-lint rules the same.
Change-Id: Ic8a2164eba3cf99e55473846e3a5fe663a3c1095
This will be useful for adopting dib-lint in other projects, in
particular tripleo-image-elements. It allows some dib-lint rules
to be used even if the project can't pass all of the checks. The
failing checks can then be fixed one at a time and removed from the
exclusions list.
For consistency, this change reads the new exclusions from tox.ini
in the same way as flake8. To use the exclusion mechanism, the
the following section can be added to tox.ini:
[dib-lint]
ignore = sete setu setpipefail

The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.
Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.

Currently when dib-lint finds a problem it does something like:
echo "ERROR: Problem found"
rc=1
This is repetitive and error-prone since it's easy to forget to set
rc to actually fail the check. This change makes those two steps
a single function call.

With this change, dib-lint ensure elements do not use tab
indentation. The following files are checked:
- executable file
- .md file

If scripts are not set -e then errors can be ignored, causing more
confusing failures later.
Also adds an exclusion comment to the ramdisk init script since we
don't want that to exit on failure.

There are certain scripts (such as the ramdisk init script) that
need to ignore linting rules for one reason or another. This adds
support for exclusions via a comment in the file like:
"# dib-lint: disable=executable sete"
There should be no ", but I need those to prevent git from treating
that as a comment. This syntax is similar to the pylint exclusion
mechanism.
Exclusion support is added to the executable check, but not
the alphabetical ordering one because I can't imagine a reason we
would need to disable that, and I don't know that comments are
supported in those files anyway.

This will provide a place to put checks that catch common errors
in elements. To start, this just checks that files starting with

save_image is used to copy kernel and ramdisks out of the image, which
we will sometimes want to keep the source, and sometimes not. However
for the main image itself, the temp copy is never kept, so use mv
rather than cp and avoid the excess IO.

In fb246a02eb we introduced an
ext4 option to allow root filesystems to be resized up to 1PB.
This appears to cause an ext4 resize2fs bug in some images.
When the issue occurs an image will hit a kernel bug when
cloud-init runs the resize2fs command during first boot:
kernel BUG at fs/ext4/resize.c:409!
In this commit we add a new option for max-online-resize
which can be used if a really large root partition is
desirable.
The root cause of all this is really a design problem in
DIB/TripleO at the moment in that we shouldn't have to worry about the
max size of the root file system when creating our images. Ideally we'd
just mkfs on the root file system itself. Much more efficient,
avoids this problem altogether...
I think the best thing to do today to avoid this is make setting
max-online-resize an option in DIB. This will allow us to stick
to the (well tested) ext4 defaults for most cases, and if someone has
need for a large root filesystem they can easily bump the setting. This
may be temporary until we either fix the design... or the ext4 fix is
released.

With smaller base images, such as Debian, the padding value used to
size the root filesystem does not leave enough room for grub which is
installed after the filesystem is created.

Occasionally cloud-init fails to resize the disk on first boot, this is
occuring because the filesystem has only 10% free. Nudging the disk size
up a bit more should give us a little more headroom so this is less
likely to occur.
I havn't been able to find out what value ensures we wont hit this
problem but I can say for sure this fixes all casses of the problem I
have seen.

Adds an option for --image-size, which sets the DIB_IMAGE_SIZE
environment variable. Having the cli option makes disk-image-create
more consistent in that parameters are able to be specified via a flag
on the command line or an environment variable. Also, you may not be
able to remember all the environment variables that you can tweak, yet
--help will tell you about the cli parameters. Preserves the old
behavior as well where if DIB_IMAGE_SIZE is set in your environment, it
will be honored.
