0ff3b94c86 Remove framebuffer video drivers from ramdisks.
We now forcibly remove all framebuffer video drivers from ramdisks, as
part of our ongoing effort to keep every kernel we boot, in text mode,
so it can be more easily intercepted by LOM hardware, nova console
logging, etc.

43c0082aa7 Move /tmp/ccache setup to base element
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.

e29cc0c10c Use lazy umount to avoid race problems with dev
A problem with unmounting the dev filesystem in Ubuntu images caused
the umount of the /dev bind mount to fail, which left it there to be
removed during the mv -t step, causing the build host's /dev to be
wiped out.

The lazy umount will detach it from the filesystem hierarchy and then
clean up the mount reference later.

fefc28a918 Add option --min-tmpfs <size> to disk-image-create
In some scenarios, the required space in the tmpfs partition can be
larger (or smaller) than the default one, producing errors due to
the lack of enough space (or performance penalties for not using
tmpfs).

Using --min-tmpfs <size>, we can hint the working set size we'll need
and let dib choose to avoid or use tmpfs.

dbfca7a816 Combine compress and save image into one function
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.

357c2de681 Remove explicit sudoers requirement.
Most of our build process runs as root and the overhead of explicitly
tracking sudo commands in the shipped sudoers.d file, plus the
operational overhead of keeping the sudoers.d file updated on build
hosts over time, is now considered to be unnecessary.
Instead, we now document that the build process will expect sudo
commands to work and the operator must make this happen (either by
running as root, via sudo -E, or allowing passwordless sudo for the
build user).

then a user will be provided a in target shell taking over from where the
last failed command left off.

92fa96b2f6 Add needed symlink for Fedora deployment ramdisk.
Symlink /usr/lib -> ../lib for Fedora deployment ramdisk.  This
symlink is needed for systemd-udevd.  Otherwise, the network device is
not loaded and initialized when the deployment image is booted.  This
logic was previously contained in
elements/deploy/root.d/50-redhat-prepare-fs, but now that ramdisk
images are built in a chroot, the change needs to be moved so that it
is applied to the ramdisk build.

e79968f682 Only remove $TMP_BUILD_DIR on cleanup
During ramdisk cleanup if for some reason the filesystems mounted
in $TMP_BUILD_DIR were not removed this recursive delete ended up
deleting parts of the host filesystem that were mounted (in particular
most of the contents of /dev got removed.

This commit doesn't deal with the reason the filesystem didn't unmounted
but ensures the consequences are not as severe.

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.

b2f1d4e2af Document an interface for offline operation.
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.

Many python extensions are built from source each time an image is

that waste. A cache dir outside the chroot is used to speed up
subsequent image builds.
