A user running di-b several times while developing an element may not
want to drop to a shell in all cases but may only want to do so if one
of their in target hooks failed.
This patch gives them the ability to do so, If break=after-error is set
then a user will be provided a in target shell taking over from where the
last failed command left off.

Scripts test for existence of ../share/diskimage-builder and
fall-back to ../ if not found. This allows scripts to run unmodified
from a packaged installation or a local archive/repository.

- 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.

Complex image builds can download hundreds of MB of data from the
internet with many separate lookups. It would be nice to allow users
to ask for a fast build where those lookups are entirely avoided,
using locally cached resources (where possible). This new interface
allows users to signal to elements that they wish to operate without
updating cached resources, which will in turn allow us to avoid
checking for stale data at all.
As part of this I've also documented where we cache data, so that
things like the ccache cache dir and image cache files are not a
surprise to users.

Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.
This fixes bug 1194055.

The recent change to use loopdev instead of nbd stopped
honoring the DIB_IMAGE_SIZE setting.
This change adds it back, by resizing the image to
DIB_IMAGE_SIZE GB, if specified. If unspecified, it resizes
the image to (actual usage + 20%), as it did before this change.

When partition tables are added to loopback devices, this can set off a
chain of udev hooks that may still be holding the loopback open. Failing
to detach loopback devices was the reason we were seeing leaked tmpfs
volumes.

Ramdisk-image-create sources both img-functions and ramdisk-functions
causing duplicate functions. To correct this situation this patch
removes the import of img-functions from ramdisk-image-create.
It moves cleanup_dirs and run_d functions from img-functions to
common-functions to allow this.

For machines with low RAM (or no access to /proc/meminfo) the builder
will still run, but will just build inside the filesystem that is
hosting /tmp. This will result in a slower build (especially if there
are a lot of .deb packages installed).

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.

Post install scripts are useful because they can perform tasks you want
to handle after the OS/application install but before the first boot
of the image. e.g: Clean the cache left by the package manager reducing
the size of the image.

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.

This will write two files in /etc/ that contain the environment and
command line arguments used in the creation of an image. This should

When an element is seen in one of those lists, it will be chosen and will continue with the next element.

Remove the explicit installation of an English language pack and instead
just default LANG to C. This settls Perl's noisy warnings and also stops
any side effects of different language build hosts.
Note that this is set right at the start of the build process, so it
should be entirely possible to override if needs be.
