Add armhf support. ARM doesn't have a generic Linux image due to the soc-specific nature of Linux kernels today, so we drop the manual installation of that package, replacing it with a dist-upgrade instead. This involved tweaks to the dpkg and fedora install-package scripts. Change-Id: I97924b80ca87781307e1087b9fe4b18215770e84 2013-04-08 03:10:34 +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 -e all the things Using set -e in all of our scripts will prevent some subtle bugs from slipping in, and will allow us to enforce use of set -e with tooling. This change also adds -u and set -o pipefail in the less complex scripts where it is unlikely to cause problems. A follow-up change will enable those options in the complex scripts so that if it breaks something it can be reverted easily.

Add option to skip update packages in same cases it is required to avoid update all existing packages, doing so can result in release update which is currently not possible unless you not include "base" element. "base" element used for most distribution (rhel, debain), and is necessary for most cloud operations, this patch add "DIB_AVOID_PACKAGES_UPDATE" parameter to skip updating all packages. usecases for this patch can be: * Avoid release update when building old release ex. RHEL7.5. * build on network-less environment. usage: DIB_AVOID_PACKAGES_UPDATE=1 or DIB_AVOID_PACKAGES_UPDATE=0 Change-Id: I71192b23c8f0bc48b348fe7377bf8a2399b53792 2019-02-10 14:07:06 +00:00			`if [ ${DIB_AVOID_PACKAGES_UPDATE} -eq 0 ]; then`
