If you check logs like [1] it's literally thousands of lines of the
same thing over-and-over as the git caching happens. It is basically
all just noise unless you're debugging it specifically. Up this to
tracing level 2 ("-x -x") to see it. Add a note in the help about
multiple flags, which has always been intended but not documented.
Image builds should continue to run with single "-x", but we could
probably greatly increase signal:noise ratio in the logs with a little
more judicial use of this to turn down some of the very noisy &
repetitive parts.

This cuts the image size down alot, esspecially if there were lots of
small file deletes.
The fstrim utility is in the util-linux package and should be on

A reduction of 25% or more in size is common.

In the common case of not specifying a size, we are already running
"du" over the image to figure out how big it is. Leverage that by
saving it's output and displaying a pruned list of big files when
requested.
We add a flag to show a summarised option (files >10MiB) and another
to show full output, should you wish that level of detail.

Being able to discover DIB's version from the command itself is
convenient. This patch adds a --version option to the disk-image-create
command, failing gracefully if diskimage-builder is not installed.
This adds an explicit dependency on pbr to the requirements since this
is required to run diskimage_builder/version.py outside of a test
environment.
This patch consciously chooses to only provide the long-form option
and no '-v' to allow for the future possibility that a '-v' might
indicate '--verbose' in the future.

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.

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.

external elements dealing with the label would need to be updated

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.
