These options have always been a bit of a mess since v2 when we added
all the block-device flexibility. Add some explicit documentation to
try and help explain the relationship between these options and the
block-device config.

While trying to get docker image pre-caching to work we couldn't get a
docker daeomon to run within the chrooted environment. However we got
docker running with the help of bwrap outside of the chrooted
environment. The only option so far for this is the block-device.d
phase. But this has the problem that it runs after the image size has
been calculated. This leads to broken builds if the docker images
being pulled are big.
This can be solved by adding a post-root.d phase that runs outside the
chroot but before the image size calculation.

In exploring Gentoo caching, it was realised that we have no way to
bind mount the cache into the finalised image for the finalise.d
phases.
By adding a pre-finalise.d phase that runs outside the chroot, we can
mount outside things into the hierarchy at $TMP_BUILD_DIR/mnt which
are then seen by the in-chroot finalise.d phase.
This is similar to the pre-install phase

Some minor things after looking at these parts.
The dib-run-parts element doesn't do any of the copying any more, so
these comments are wrong.
The reason for the multiple mounts in the bind mount was non-obvious
to modern eyes (as util-linux has handled this for some time).

systemd-resolved has a new behaviour in bionic, in that if there is no
/etc/resolv.conf file when it installs, it assumes it is a fresh
system and makes /etc/resolf.conf a symlink into its compatability
files.
dib ends up saving & restoring whatever /etc/resolv.conf we have after
the inital chroot creation, which may not be what we want -- in the
above case it restores the system-resolved symlink. For
openstack-infra, we use unbound and want simply "127.0.0.1" in a
/etc/resolv.conf file [1].
Formalise the ability to save specific contents into the final image.
Add documentation, and a note in the code that it's an external
interface.
I would have preferred to namespace the .ORIG file with DIB_ or
similar, but this unofficial interface has already escaped into the
wild. Leave it as is for simplicity.
[1] Note that systemd-resolved will obey /etc/resolv.conf as you would
expect, if file exists.

Whilst working on the Reproducible Builds effort [0], the team noticed
that diskimage-builder could not be built reproducibly as it iterates
over XML elements in a non-deterministic order when generating the
documentation. This patch sorts the elements, and is a forward of the
patch sent to the Debian BTS [1].

This moves the block-device default out of the "vm" element and into a
selection of other elements. There's "mbr" which retains the status
quo. There's an EFI version that has the boot/grub partitions as
required. In between there's the GPT only version, which is useful
for architectures like power without EFI, but still want possible
larger disks using GPT.
Change-Id: I4a566a97d073fc0dda0ab2494ac988fe015800a9
This adds support for a GPT label type to the partitioning code. This
is relatively straight-forward translation of the partition config
into a sgparted command-line and subsequent call.
A unit test is added based on a working GPT/EFI configuration and the
fedora-minimal functional test is updated to build a single-partition
GPT based using the new block-device-gpt override element. See notes
in the sample configuration files about partition requirements and
types.
Documentation has been updated.

s390x architecture uses zipl as bootloader. When used in combination
with the vm element it replaces the existing bootloader element.
It's mandatory for s390x vm images.
Use cases
---------
* Allow users to create s390x images that run on nova with s390x
libvirt/kvm backend
* Building nodepool images for s390x third party CI
Supported Distros
-----------------
The following listing shows all Distros that officially support
s390x and how those Distros are supported in DIB with this patch.
* SLES - not supported (SLES is not supported in DIB)
* RHEL - not suppoprted (RHEL is not supported as KVM guest on s390x,
therefore there's no rhel7 qcow image for s390x available
like it is for other archictectures)
* Ubuntu - supported
Ubuntu images can for example be built using the following commands:
$ disk-image-create ubuntu-minimal zipl vm
$ disk-image-create ubuntu-minimal zipl
$ disk-image-create ubuntu zipl vm
Testing
-------
Cross architecture building of s390x images is not supported so far.
The plan is to set up a ThirdParty CI that builds the image for s390x and
provides the logs.

Testing on a ubuntu cloud image, the build is not possible
because it is missing the kpartx dependency. Adding that
as a requirement, when producing images with partitions.

The MBR Partition Table Entry (PTE) allows one to specify many
possible partition types and one of the benefits of this is being able
to specify the CHS variant or the LBA variant.
By default, LBA only creates partitions of type 0x83 (of course,
that's only because the documentation doesn't tell you how to make it
do anything else).
I will take up Ian's suggestion in patch set 2 for a more rigorous
test in an independent patch set.

This moves to a more generic config parser that doesn't have plugins
parsing part of the tree.
I understand why it ended up that way; we have "partitions" key which
has special semantics compared to others keys and there was a desire
to keep it isolated from core tree->graph code. But this isn't really
isolated; you have to reverse-engineer several module-crossing
boundaries, extras classes and repetitive recursive functions.
Ultimately, plugins should have access to the node graph, but not
participate in configuration parsing. This way we ensure that plugins
can't invent new methods of configuration parsing.
Note: unit tests produce the same tree -> graph conversion as the old
method. i.e. this is not intended to have a functional change.

This patch finalizes the block device refactoring. It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.
Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.

* unmount_dir : modified to only unmount the subdirs mounted by
mount_proc_sys_dev(). dib-block-device unmounts

Currently there is no description of dependencies in the generated
documentation of the elements: therefore a user of an element does not
know which other elements are automatically included and e.g. which
configuration options are available. In addition there are some
copy&pastes of parts of the README.rst scattered thought different
Ubuntu and Debian specific elements.
This patch adds a semi-automatic generation of dependency information
of all elements. Nevertheless these are not automatically included.
The author of the element's README.rst can decide if and where the
dependency information should appear and can use the descriptor
.. element_deps::
for this.
This patch adds the dependency information for some Debian and
Ubuntu patches - and creates the base for later removing the
duplicated parts.
A call is added to element_dependencies._find_all_elements() to
populate reverse dependencies for Element objects.

It seems that pbr's "warnerrors" isn't actually doing anything at the
moment (I680b448471e687919d202e8f2abe57f8ba3b22ee) meaning we're able

dib_[environment|args] manifest files are currently generated by the
base element and then moved by the manifest element.
This creates too many corner cases -- if you don't include the base
element (we are trying to empty it ATM) you don't get the env/args
saved at all; if you include base but don't include the manifest
element they're saved to /etc, but if you do have the manifest element
they're moved to the manifest dir.
Move generation of these into the manifest element directly and update
the documentation to reflect this. In practice this doesn't change
things, because the "manifests" element gets pulled in via deps for
most builds.
