The "set to localhost by default" behavior for manage_etc_hosts has been
deprecated for more than a year now by change
Ia8582883f737548e2911d3f36a1943e5b236281b.
Setting that value to "localhost" is still possible, but it won't be the
default anymore. If the previous behavior of assigning the hostname and
FQDN to 127.0.0.1 is still desired in some environments, it can be
achieved by setting the DIB_CLOUD_INIT_ETC_HOSTS environment variable,
as the deprecation warning message suggested.

Diskimage-builder currently writes cloud-init config file which adds a
host entry mapping the hostname and FQDN to 127.0.0.1 into every image
built. This is probably useful for some use cases but not for all, so we
now allow customizing the manage_etc_hosts value via
DIB_CLOUD_INIT_ETC_HOSTS variable and also not writing the config at all
if that variable is explicitly set to an empty string (currently the
default is 'localhost' but in the future the default will be empty
string).
Particular description of the problem this causes in TripleO follows:
We get hosts files like this:
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
127.0.0.1 ov-rl5i5saoc6h-1-hj5tzsbrdv4c-controller-dy6nuyarqy5z.novalocal ov-rl5i5saoc6h-1-hj5tzsbrdv4c-controller-dy6nuyarqy5z
# HEAT_HOSTS_START - Do not edit manually within this section!

192.0.2.15 ov-rl5i5saoc6h-1-hj5tzsbrdv4c-controller-dy6nuyarqy5z ov-rl5i5saoc6h-1-hj5tzsbrdv4c-controller-dy6nuyarqy5z.novalocal
192.0.2.16 ov-rl5i5saoc6h-2-a6v7saxnivm5-controller-7jboskte34r7 ov-rl5i5saoc6h-2-a6v7saxnivm5-controller-7jboskte34r7.novalocal
# HEAT_HOSTS_END
The duplicate hostname/FQDN entry for 127.0.0.1 and 192.0.2.15 confuses
Corosync, which then fails to start a cluster when using hostnames in
the config file instead of IPs.

Partial-Bug: #1447497
vconfig is actually deprecated in favor of the ip command, and is not
available on some newer distros (RHEL 7 at least). I'm not honestly sure
why it needs to be installed in all images anyway. I traced the origins
of installing the vlan package here all the way back to the first dib
git import from some other repo...so, I don't see any obvious reason why
it needs to be installed.

Turns out that updating packages last causes some pretty
non-intuitive behaviour if you are trying to pin a package
to a specific version. Lets just update the base RPMs first...
subsequent installations should install the most updated version
anyways (unless they are pinned).
Also moves the package-installs script from the 00 step to 01 so
we can do the update first.

Not all operating-system elements install cloud-init, but the base
element assumes its existence. Create the directory if it does not
exist.

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.

When set to true this cloud-init setting overwrites the /etc/hosts
file at reboot, breaking stuff in TripleO where controllers rely
on resolving each other by name. We still want cloud-init to add in
there a mapping for the local fqdn, so we switched to 'localhost' [1]

With this change package name to distro mappings used
within the base element are now stored in the top
level pkg-map file.
Additionally, all bin/install-packages commands are updated
to use the -m option so that the base element pkg-map
namespace is used by default.

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.

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.

Since we are using bash syntax in some of the element fragments,
we should make sure we use bash for all of them, so that things don't
break on systems where /bin/sh != /bin/bash.

In the 51-grub hook, after the GRUB installation, the script will look
for a GRUB configuration file and in case it's not present one will
be generated using the grub-mkconfig command. The reason why it have
to be done is because the new Fedora 19 cloud images is using extlinux
by default.

Many python extensions are built from source each time an image is
built. Repeating these is wasteful, so ccache is employed to eliminate
that waste. A cache dir outside the chroot is used to speed up
subsequent image builds.

Apply kernel command line parameters to force Linux to remain in text
mode. Typical distro kernels quickly switch into a graphical screenmode
and this is incompatible with common Lights Out Management hardware
which is able to intercept text mode consoles to display them remotely.

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.
