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.

====== debian ====== Create an image based on Debian. We default to unstable but DIB_RELEASE is mapped to any series of Debian. Note that the default Debian series is `unstable`, and the default mirrors for Debian can be problematic for `unstable`. Because apt does not handle changing Packages files well across multiple out of sync mirrors, it is recommended that you choose a single mirror of debian, and pass it in via `DIB_DISTRIBUTION_MIRROR`. If necessary, a custom apt keyring and debootstrap script can be supplied to the `debootstrap` command via `DIB_DEBIAN_KEYRING` and `DIB_DEBIAN_DEBOOTSTRAP_SCRIPT` respectively. Both options require the use of absolute rather than relative paths. Use of this element will also require the tool 'debootstrap' to be available on your system. It should be available on Ubuntu, Debian, and Fedora. The `DIB_OFFLINE` or more specific `DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE` variables can be set to prefer the use of a pre-cached root filesystem tarball. The `DIB_DEBOOTSTRAP_EXTRA_ARGS` environment variable may be used to pass extra arguments to the debootstrap command used to create the base filesystem image. If --keyring is is used in `DIB_DEBOOTSTRAP_EXTRA_ARGS`, it will override `DIB_DEBIAN_KEYRING` if that is used as well.
