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.

2f6fdb4142 Fix sourcing of environment files
Includes "Don't match editor backup files in environment" and "Order
execution of environment.d scripts". These had to be squashed because
the first change alone changes the order env.d scripts are sourced in.

The current glob match for environment files can source editor backup
files (foo.bash~) which will override the real changes you have made.
Other parts use the regex to avoid matching such files, so do
the same for environment file matching.  Note this has to match "."
unlike the other regex, as most env files are "foo.bash"

Also sort the files before sourcing them to ensure a reliable order.
This change should be in line with current expectations, given the
convention is to numerically prefix scripts in this directory.

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.

1c07d4ba1a Remove All Rights Reserved
The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.

Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.

Remove all of the lines, because sanity.

381ff6ab1d Fix set -eu and pipefail failures
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.

f760f11050 Don't hardcode environment.d
Don't assume environment.d is always under /tmp/in_target.d. This makes
dib-run-parts more flexible, and less specific to diskimage-builder. For
instance, dib-run-parts is already used by os-refresh-config, but
/tmp/in_target.d/environment.d is never going to exist when it's called
by os-refresh-config.

This is useful b/c elements can now install os-refresh-config scripts
under /opt/stack/os-config-refresh/environment.d to influence how
further scripts are run. Specifically, the OpenSuse packages prepend the
OpenStack user accounts with "openstack-". Instead of checking for which
users exists with an if/else in all the os-refresh-config scripts that
need to do user related things, we can just update the scripts to use
$NOVA_USER, etc. The OpenSuse element can then install a file under
/opt/stack/os-config-refresh/environment.d to set NOVA_USER to
openstack-nova. We could have files that declare defaults as well within
each specific element, or just set a default variable at the top of each
os-refresh-config script.

79f31d0476 dib-run-parts should dereference symlinks
dib-run-parts should dereference symlinks, and if they point to an
executable file, execute that file as a script. This can be accomplished
by using the xtype predicate in the find command instead of the type
predicate.

This change is needed so that we can dynamically symlink hook scripts
into hook directories such as install.d at runtime to support different
install types.

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.

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.
