When compressing an image, this is done in the same dir where the raw
image resides, doubling the amount of space needed (scarce when
using tmpfs), and then it's moved to the .cache folder in disk.
Combining these two functions, we reduce the amount of space needed
in the tmpfs partition (when in use), and the compressed image is
created directly on the .cache folder disk, so there is no need to
move the compressed image after the process into disk.

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.

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.

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.

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

with a dist-upgrade instead. This involved tweaks to the dpkg and fedora

Remove the explicit installation of an English language pack and instead

Note that this is set right at the start of the build process, so it
