Ensure the return code of element-info is actually checked by moving the
export IMAGE_ELEMENT to the subsequent line.
A recent change (Ic0a061995e2ae708c95a535cba6237bff58f7d93) exported the
IMAGE_ELEMENT variable. This caused the return code of element-info to not
actually be checked, since the export command is now checked instead and
almost always will return 0.
This caused a misleading error message when using diskimage-builder with an
unknown element since the script didn't exit when it should have:
$ bin/disk-image-create -a amd64 foobar vm
Building elements: base foobar vm
ERROR: Element 'foobar' not found in 'bin/../elements'

As part of this change we expose DIB's IMAGE_ELEMENT variable

This change is intended to decouple elements from DIB
and allow new elements to support multiple distributions

constantly maintain DIB's various bin/map-packages files.

If the tmpfs being used to hold the image filesystem is close to being
full then housing the raw disk image in the same place can be
problematic as it tends to grow faster then the filesystem shrinks when
data is being moved into it.
Putting them both into separate tmpfs's will allow there to be an
overlap where they jointly use more then the size limit for a singe tmpfs.

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.

The sbin paths (/sbin, /usr/sbin, /usr/local/sbin) need to be in $PATH.
Since $PATH is set in the build environment from the host, if the host
does not have these paths set, they need to be added to $PATH. In
particular, they must be set for apt-get which calls out to ldconfig,
start-stop-daemon, etc.
The previous check was insufficient because if you had /usr/sbin or
/usr/local/sbin in your $PATH, the addition to $PATH was not done since
the "if" statement evaluated to true.

Commit c7d80dd (Cleanup mount points automatically) removed the unmount
of $TMP_MOUNT_PATH/tmp/ccache in run_d_in_target() and moved the
"rm /tmp/ccache" to elements/base/finalise.d/02-remove-ccache. There
are two problems with this:
1) Not unmounting at the end of run_d_in_target() results in tmp/ccache
being bind mounted muliple times on top of itself (three times, if you
just run `disk-image-create base`). It is eventually unmounted, but
somehow the auto unmount code is confused, and tries to unmount it
one more time than it was mounted, which results in an error like
"umount: /tmp/image.THQkZxQa/mnt/tmp/ccache: not mounted".
This doesn't actually break anything, but it's a little messy.
2) "rm /tmp/ccache" in elements/base/finalise.d/02-remove-ccache never
succeeds in removing /tmp/ccache, because that hook is invoked by
run_d_in_target(), *while* /tmp/ccache is mounted.
This present commit solves the above by moving the ccache setup glue out
of img-functions and into the base element's root.d. This has the
following implications:
1) lib/img-functions is a little cleaner.
2) /tmp/ccache is available in the chroot during the root, extra-data,
pre-install, install and post-install stages. It is not available
during block-device, finalise and cleanup stages as it will have been
automatically unmounted by then.
3) /tmp/ccache won't be setup if you're building an image that doesn't
include the base element.

larger (or smaller) than the default one, producing errors due to

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.

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
