33cd0fb40f dib-run-parts: make cp to target root more robust
The dib-run-parts/root.d/90-base-dib-run-parts script would mysteriously
fail whenever the dib-run-parts is not in the path.  The install
commands complaining with:

install: missing destination file operand after
'/tmp/image.ILFTBYVy/mnt/usr/local/bin/dib-run-parts'

The reason is chaining a command in exec bypasses set -e. For example:

 exec /bin/ls $(which doesnotexist)

Will works and continue.

Handle the which lookup in a variable to have the script abort
immediately whenever dib-run-parts is not found.

Left an inline comment to make sure the fix is kept around in the
future.

36b59c001c 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.

644598941c Use dib-run-parts from dib-utils
Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.

This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.

16be6d7ce0 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.

f6ba2aeaf4 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.

ee5ae03d58 Enable running disk-image-create on SUSE Linux
- Ensures /sbin and friends are in $PATH when invoked (without this,
  various sudo invocations fail in exciting ways).
- Use dib-run-parts in lib/common-functions instead of run-parts
  (neither SLES nor openSUSE ship run-parts).
- Ensure dib-run-parts doesn't descend into subdirectories (same
  behaviour as run-parts).
- Move dib-run-parts from root.d to bin (cleaner, consistent with
  other elements with separate bin scripts).
- Tested by building Ubuntu image on openSUSE 12.3.
- Note: this doesn't add support for creating SUSE images, it just
  lets you run disk-image-create on SUSE-based distros.

3464064a87 Add environment.d hook to setup environment.
Before each phase dib-run-parts will pick these up to setup the
environment for the commands it runs.

4e428c6844 dib-run-parts was failing with empty targets.
When the target directory is empty, the for loop printing our profile
data was failing because of a glob problem.

91c30f6ab2 Use dib-run-parts for running scripts in target
Also modified dib-run-parts to apply a more workable solution for
filtering out unwanted files such as editor backups and VCS.

The script is installed in its own element, depended on by the OS
specific ubuntu element. This is  because the ubuntu element (and
later other OS's) are responsible for populating the root filesystem.
If we try to install this in base, the root filesystem will look to
be populated already and we will skip automatically choosing ubuntu.
