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.

=========
manifests
=========
Copy any manifests generated into the build area post-image creation
This element should be a dependency of any element that writes a manifest
into the `DIB_MANIFEST_IMAGE_DIR`, which defaults to `/etc/dib-manifests`.
This is created in extra-data.d rather than pre-install.d to allow the
source-repositories element to make use of it
The manifests are copied to `DIB_MANIFEST_SAVE_DIR`, which defaults to
`${IMAGE_NAME}.d/`, resulting in the manifests being available as
`${IMAGE_NAME}.d/dib-manifests` by default
