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.

================
package-installs
================
The package-installs element allows for a declarative method of installing and
uninstalling packages for an image build. This is done by creating a
package-installs.yaml or package-installs.json file in the element directory.
example package-installs.yaml::
libxml2:
grub2:
phase: pre-install.d
networkmanager:
uninstall: True
os-collect-config:
installtype: source
example package-installs.json::
{
"libxml2": null,
"grub2": {"phase": "pre-install.d"},
"networkmanager": {"uninstall": true}
"os-collect-config": {"installtype": "source"}
}
Setting phase, uninstall, or installtype properties for a package overrides
the following default values::
phase: install.d
uninstall: False
installtype: * (Install package for all installtypes)
Setting the installtype property causes the package only to be installed if
the specified installtype would be used for the element. See the
diskimage-builder docs for more information on installtypes.
DEPRECATED: Adding a file under your elements pre-install.d, install.d, or
post-install.d directories called package-installs-<element-name> will cause
the list of packages in that file to be installed at the beginning of the
respective phase. If the package name in the file starts with a "-", then
that package will be removed at the end of the install.d phase.
