There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

Patch adds support to create PowerPC image with vm element.
It creates 2 partitions, one for PReP boot and other for root and
installs grub-ieee1275.

Using lsb_release to figure out what distro and release an image is
is redundant, as the same information is available in DIB_ vars.
Further, it causes errors when creating new rhel7/centos7 images

Per [1], our current root label of cloudimg-root does not work with
XFS because XFS only allows 12 character labels. This change
addresses that by allowing a custom rootfs label to be specified
in the call to disk-image-create. There should be no backwards
compatibility concerns as the default label is unchanged. Any
external elements dealing with the label would need to be updated
to support this new feature, but should continue to work as before
as long as a custom label is not specified.

When running inside a Docker container, we cannot rely on devices in
/dev/mapper to be automagically created by udev, because we probably
don't have a udev at all. To work around this, run dmsetup mknodes
after every kpartx run.

While building images in a dual boot host,
/dev/sda is leaking into build's grub config.
It is visible in the logs that the commands
GRUB-INSTALL and GRUB-MKCONFIG probes Host OS environment.
This is avoided by setting grub_disable_os_prober
to true in /default/grub config file.

The previous method only configured serial console for Ubuntu or
Fedora, I noticed this wasn't working when I built RedHat 7.
After reading about how grub-mkconfig works, I realized that we
shouldn't be using sed to modify grub.cfg, and set up the proper
variables in /etc/default/grub

Some extlinux packages install mbr.bin under /usr/lib/extlinux or
/usr/lib/EXTLINUX so tese directories need to be checked as well.
Also, there are packages that create a /boot/extlinux directory
which needs to be taken into account. Finally, commit
bccffc8bfd dropped the /boot prefix
from the kernel and initrd references in the ext/syslinux config
file which is simply a bug that needs fixing.

Initial support for a centos7 image.
This is separate to rhel7 because the major differences are things
like repo and image locations, which are always going to be different.
We should merge any real changes into the redhat-common layers.
Apart from the added support files in centos7/*, the other change is
mostly modifications to redhat-common's extract-image to handle
different partition layouts of the centos7 image.

The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.
Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.

As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later. Setting this on all existing scripts
will allow us to enforce use via Jenkins.

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.

If creating an image of a disto without grub2 extlinux is instead used,
extlinux was being configured to mount the root filesystem as
read/write which in turn causes e2fsck to fail to test the filesystem,
on RHEL 6.5 this causes the boot process to fail.

52-force-text-mode-console, running after 51-bootloader, calls
grub2-mkconfig (on Ubuntu that will happen via the update-grub call).
This call will overwrite all the changes that 51-bootloader did to the
grub.cfg. By merging the 52-force-text-mode-console code into
51-bootloader we avoid that. This also means that 51-bootloader will now
call grub2-mkconfig regardless of whether there is already and existing
grub2 configuration or not (52-force-text-mode-console did that in the
past anyway).
Additionally this commit enables the force to textmode code for openSUSE
(was previously only working correctly for Ubuntu and Fedora).

Changing the grub config makes no sense in a build not heading for a vm

element. Forcing textmode for those images would be better done in nova.

When uninstalling grub2, leave all its dependencies
including grub2-tools installed to minimise the number of packages
which need to be installed in the finalise stage.
Since the yum cache is unmounted during finalise, installing
grub2 in finalise is slowed by re-populating the yum cache.
This change copies the grub2 rpm out of the yum cache so it can be installed
from file during finalise.
This should prevent disk becoming full during finalise on Fedora.

If GRUB2 is not available in the system a fallback to install Extlinux

exporting the DIB_EXTLINUX variable.

This patch is part of a another big patch that will implement a fallback
to Extlinux in case GRUB2 is not available in the system. The reason why
it's being splitted in two patches is because git is not being able to
recognize the file changes when the rename happens in the same commit.

If you have an EFI host but the image doesn't have the EFI modules
installed the grub-install command will fail in case the --target
argument is not set. The problem is that the grub-install script will
check whether the /sys/firmware/efi file exists or not to determine if
it's an EFI installation, but this value comes from the host, so this
patch will look for the /sys/firmware/efi file and will also check if
the EFI modules are installed in the image, if not set the --target to
a non-efi platform.

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

by default.

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.
