87a18f51e3 Use megabyte granularity for image extra space
I want to use the new --image-extra-size flag[1] but my use-case
calls for megabyte granularity of this value. Rather than adding
60% to an 800MB image, maybe I only want to add 100 or 200MB, etc.

778d007150 Support defining the free space in the image
Currently diskimage-builder supports two ways to specify the image
size. One is defining a fixed image size using DIB_IMAGE_SIZE, the
other one is auto-detection while adding a security margin of 60% as
free space. This means when building larger images (e.g. >100GB) with
unknown size upfront we end up with much wasted space, IO and network
traffic when uploading the images to several cloud providers. This can
be optimized by adding a third way by defining DIB_IMAGE_EXTRA_SIZE to
specify the free space in GB. This makes it possible to easily build
images of varying sizes while still minimizing the overhead by keeping
the free space constant to e.g. 1GB.

11142f75b4 Allow specification of filesystem journal size
In many cases, the statically sized 64MB journal is far below the
e2fstools default calculation[0] which calls for a 64MB journal only
on filesystems smaller than 16GB. On bare metal in particular, the
correct default journal size will often be in the 512MB-1GB range.

Since we cannot know what the target system is, this should be a
tunable parameter that the user can set depending on the intended
image usage.

Add a DIB_JOURNAL_SIZE envvar and --mkfs-journal-size parameter
to the image creation so users can override the default journal
size.

e443700b5c Formalise saving of /etc/resolv.conf
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.

adb0341064 Add block-device defaults
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.

55b479b54f GPT partitioning support
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.

271dc36f33 Add zipl element as s390x architecture bootloader
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.

52faa0e1d9 Allow users to specify partition type in the MBR PTE
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.

00da1982ce Add a more generic tree->graph parser
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.

5e2330d89c Put MKFS_OPTS after filesystem type
mkfs's arguments are

 mkfs [options] [-t type] [fs-options] device [size]

So it seems our MKFS_OPTS are really supposed to be fs-options, rather
than options to mkfs itself.

Why didn't we notice?  It's quite a trap -- mkfs.ext2 has a "-t"
option, so when we're calling

 $ mkfs -i 4096 ... -t ext4 ...

We actually just fall-back to the default from the mkfs wrapper which
is mkfs.ext2 which works!  But when you make that, say, xfs, we're not
calling the right wrapper at all.

Also update documentation

d65678678e Move dib-run-parts into diskimage-builder
Move dib-run-parts from dib-utils into diskimage-builder directly.

For calling outside the chroot, we provide a standard entry-point
script.  However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element.  I believe this to be the KISS approach.

This removes the dependency on dib-utils.  We have discussed this
previously and nobody seemed to think retiring dib-utils was going to
be an issue.

This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

3d48a528c1 Refactor: block-device handling (local loop)
Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.

This patch factors out the creation and deletion of the local
loop image device handling into a python library.

The main propose of this patch is to implement the needed
infrastructure.  Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

0c32784663 Revert "Zerofree the image if possible"
This reverts commit 5184d02a7c.

The decision was made to go with fstrim because it is faster and more
universal that zerofree. The related-id has the patchset that implements
fstrim.

5184d02a7c Zerofree the image if possible
If the image has an ext filesystem and the zerofree utility is present
on the build system then run zerofree. This should make images as
compressable as possible which is a nice feature when building
compressed qcow2 images.

24d1527111 Move speedup section to image building guide
speedup section explains  the user how to sppedup image build by using
tmpfs. The  correct user guide to have this section, is the user guide
about image building rather than the installation user guide.
