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.

The dpkg element was hardcoding ~/.cache/image-create as the cache path,
but elements should use DIB_IMAGE_CACHE as the root for the cache to
allow users to override the path. Replace the hardcoded path with one
that is rooted at $DIB_IMAGE_CACHE.

The docker build folks obsess about image size and speed a bit. Grab a
few of their optimizations from their debootstrap build process and
apply them to ours.

I would like to recommend to use + instead of \; in the find
command. As this will ensure the removal of all selected
directories in a single invocation.
Hence improve the speed of deletion.

With this patch, /var/cache/apt/archives directory content is preserved.
The directory is actually a bind mount of the
~/.cache/image-create/apt/$DISTRO_NAME directory, much like what we do
for ccache.
You can use DIB_APT_LOCAL_CACHE=0 to disable this behavior.
This trivial change improve performance A LOT (>30%), even if a local
HTTP proxy because:
- there is no need to copy again and again the same files
- we avoid network latency
The patch has been tested with Debian and Ubuntu with every elements
from the tripleo-image-elements repository, the final size of the cache
directory is about 700MB per distribution subdirectory.

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.

Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e. This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

Currently the dpkg element fakes start-stop-daemon, initctl and
invoke-rc.d to stop dpkg from starting a bunch of daemons in the
chroot. This is problematic when packages use service, start, stop or
restart commands.
This patch uses a policy-rc.d instead of faking invoke-rc.d to achieve
the same thing. This approach now aligns exactly with debootstrap.
Without this patch DIB runs on some debian distributions fail
when trying to umount the chroot loop device as there are daemons
running.
The log will now show "invoke-rc.d: policy-rc.d denied execution of
start." instead of "Warning: Fake invoke-rc.s called, doing nothing."

Check if Upstart exists before blocking the daemon. Not all dpkg based
OS's have Upstart installed so this should help increase compatibility.

This includes the install-packages implementation for dpkg, apt http proxy
config, daemon blocking and unblocking.
