Store build-time settings 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. Change-Id: Icdbe6693380bed6c406feee10d2cb1a88a992932 2013-04-04 19:38:19 +00:00			`#!/bin/bash`

Standarise tracing for scripts 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.

set -u and -o pipefail everywhere 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. Change-Id: Iad2d490c86dceab148ea9ab08f457c49a5d5352e 2014-04-03 02:24:15 +00:00			`set -eu`

Store build-time settings 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. Change-Id: Icdbe6693380bed6c406feee10d2cb1a88a992932 2013-04-04 19:38:19 +00:00			`source $_LIB/die`
