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.

Changing the grub config makes no sense in a build not heading for a vm
and may fail because grub is removed from images not including the vm
element. Forcing textmode for those images would be better done in nova.

Manually listing the mount points that need cleanup is not
maintainable and makes it hard to write elements that use bind
mounting to inject resources into the build environment.

In the 52-force-text-mode-console hook, gracefully exit when the
/boot/grub2 directory does not exist on the Fedora 19 cloud image
filesystem. By default the Fedora 19 cloud image is using extlinux to boot
the image instead of GRUB. The decision was taken because GRUB is quite
big (would pull in ~30MB of dependencies) and there's very little benefit
in using it because cloud images don't need to cover all the corner cases.

In the 51-grub hook, after the GRUB installation, the script will look
for a GRUB configuration file and in case it's not present one will
be generated using the grub-mkconfig command. The reason why it have
to be done is because the new Fedora 19 cloud images is using extlinux
by default.

Setting up a routine to run at first time the system boot may vary from
distribution to distribution. This patch will remove the logic from the
diskimage-builder code and put it into the elements.
The base element will now deploy a dib-first-boot script and each OS
element will ensure that this script runs at rc.local time. By doing
that we will put the OS specific stuff in the OS elements and remove
the embedded code out of the img-function file.
