Add redhat-common element Add an element intended for use in both Fedora and RHEL. This allows them to share install steps that are common to both. Change-Id: Ie4e820a7b777b8701514351b1f802cfe57c3812e 2014-02-18 22:14:43 +00:00			`#!/bin/bash`
CentOS 6 Element This is the centos element, which builds CentOS 6. There are a couple of modifications to redhat-common because the version of tar in el6 doesn't support --xattrs-include. There is a change to both pkg-map and svc-map to add 'centos' to the 'redhat' family. Also explicitly have to install cloud-utils growroot and dracut growpart for proper fsresize at instance launch. Also sets the DIB_EXTLINUX variable because there is no grub2 for this distro.

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`

Cleanup yum downloading Using "yum --downloadonly" breaks the abstraction of "install-packages" because it downloads to the yum cache. It also acts funny if the package is already there. Add an argument to "-d" which is the directory to download to. dnf has "download" built in, and for the old case use yumdownloader which acts about the same. Ensure it is installed, since it comes in yum-utils. Also a slight cleanup of the getopt parsing so it's easier to have the required argument for -d Thus we can remove most of the stuff in 15-remove-grub. The check for centos6 and it's lack of grub2 is clarified. All the stuff about having to remove the package, purging the cache etc so yum gets the right thing is no longer relevant. The long section of commented out code at the end is also removed for clarity. I tested this with an F21, F22 & centos (6) build Change-Id: Id1e430e7d050a0b99ac449e2ea435e06cda1c4e6 2015-05-29 00:24:15 +00:00			`# grub2 isn't available on rhel6/centos6; they are setup to use`
