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.

Adds new disk-image-create --install-type option which
can be used to enable alternate install types. The
default install type is 'source'.
The motivation is to eliminate elements like
enable-package-installs which require coupling and also
don't work with elements in multiple element repositories.
This patch does not prevent you from using the previous
DIB_INSTALLTYPE_ variables to customize the install type,
rather it just changes the default so you don't have to
set it so often when using things like packages.

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.

The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.
Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.
Remove all of the lines, because sanity.

Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e. This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

Move whether the package or source install type is enabled out of the
source-repositories element and into the base element.
source-repositories wasn't a great fit for this functionality to begin
with.
Specify the install type for an element via the
DIB_INSTALLTYPE_<install_dir_prefix> environment variable.
Additionally with this approach, any new install type can be added
in an element, without having to update source-repositories or anything
in dib.
You could just write your install type implementation under
nova-foo-install, then define DIB_INSTALLTYPE_nova=foo in your
environment, and the scripts under nova-foo-install would get run during
the image build.
Source installs (any scripts under <install_dir_prefix>-source-install)
is the default install type for all elements.

This will write two files in /etc/ that contain the environment and
command line arguments used in the creation of an image. This should
assist with later efforts to repeat the creation of an image.
