Two bugs are addressed.
1) The sysprep element was broken in that it only truncates
/etc/machine-id, but not /var/lib/dbus/machine-id. systemd will
not generate a new machine-id if /var/lib/dbus/machine-id is
present[1], it will simply copy it to /etc/machine-id.
We observed machine-ids being packaged in /var/lib/dbus/machine-id
on several distros: Ubuntu Bionic, Fedora 29, Debian Stretch.
CentOS 7 and Ubuntu Xenial do not contain packaged machine-id as
far as I can tell.
All test builds were performed using -minimal elements.
2) A second bug existed where debian-minimal did not run the sysprep
element at all, so a stretch image I tested contained a populated
/etc/machine-id AND a populated /var/lib/dbus/machine-id.

linux-firmware and linux-firmware-whence (meta package for mostly iwl
firmwares) packages account for approx. 289 M install size on a F30
system, and linux-firmware for approx. 176 M on CentOS 7. Users needing
these firmwares are eventually baremetal users and are not looking for a
very minimal operating system base install like virtual image users are.
Thus, a non-minimal OS element is better suited for them. Alternatively,
it could be later considered a dedicated firmware element.
This is inline with I8ce65e1d357d15e8ed8995ad1dcaea02bbd1986f.

This is a follow-on to I475a253091cbaf63687b91c748c31a6753bb0f57 as we
are still seeing issues on some clouds with unconfigured networking.
We increase the timeout, but also make it configurable so we can
fiddle it without a dib release in the gate.
To follow-on from the experimentation done by clarkb, I can confirm by
emperical testing on a Centos 7 image (from today, today being this
change's date) that setting
net.ipv6.conf.all.autoconf=0
by itself is "fatal" and the interfaces do not come up; i.e. nm does
not by default seem to re-enable ipv6 for the interface. However,
explicitly adding:
IPV6INIT=yes
IPV6_AUTOCONF=yes
to the interface file *does* seem to make it work, even if
"all.autoconf=0" is set (then again, there's also bugs about the
effect of this [1]). However, no extant distribution (I can currently
find) does anything like this by default.
If this continues, this may be an option. Another might be to avoid
the use of the nm-settings-ifcfg-rh profiles and move directly to nm
ini files with glean.

As noted in the change, 7fd52ba841
increased the size of the EFI partition considerably. This has meant
that our padding upwards of the disk size is insufficient and EFI
builds (arm64 in particular) is failing due to out-of-disk errors
during final image operations like installing kernels.
Similar to the discussion we had in
I65fa13a088eecdfe61636678578577ea2cfb3c0c, this feels a bit ugly
because we're mixing logic here with sizes specified in block-device
config files. But it boils down to the same problem; we are
calculating the disk size here and passing it to the block-layer, so
unless we want to make large changes to the status quo about where
these sizes are calculated, small adjustments here are the most KISS
solution.
Thus we check if we have selected the EFI bootloader element, and thus
assume there will be a large system EFI partition and expand the disk
size accordingly.

This element configures systemd to send its journal to the console,
which can then be retreived by server commands. In the case of
nodepool, if the image failed to boot the console will be dumped into
the logs when nodepool decides the node is not responding. Having
this can be very helpful diagnosing early boot errors.

This patch adds a new environment variable to the ubuntu-minimal
element called DIB_UBUNTU_KERNEL that allows you to specify the kernel
meta package that will be using to install the kernel inside the image.
It supports "linux-image-generic" (The default), "linux-image-kvm", and
"linux-image-virtual".
This allows building images that are smaller in size (~200MB smaller
qcow2) that have only the kernel modules necessary for virtual
machines.

Transaction check error:

The rhel7 element is deprecated and is left only for backward
compatibility.
The rhel element should be used instead. Users should set DIB_RELEASE to
'7' to indicate which release you are using.
The new element is a version-less RHEL element to handle both '7'
and '8' DIB_RELEASE, which aligns with other elements which operate in
the same way such as the Fedora element.

Make a version-less RHEL element to handle both '7' and '8' DIB_RELEASE.
The element usage should align with other elements which operate in the
same way such as the Fedora element.
Additionally, this patch adds support for RHEL8 that operates with
Python 3.
As of now, users of diskimage-builder will still be able to use the
'rhel7' element, or migrate to 'rhel' and specify their respective
DIB_RELEASE value.
* mount the xfs file-system for extraction as read-only. vaguely
based on explaination in [1] and the fact we only read the image
data into a tar, so can ignore this.
XFS (dm-1): Superblock has unknown read-only compatible features (0x4) enabled.
* Use the redhat system python as the dib-python version. dib was
ahead of it's time making an abstracted python interpreter for
system work ;) the system python should work for running the various
dib element scripts.

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.

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.

This plumbs through an "--use-nm" flag to glean which instructs it to
setup interface bringup with NetworkManager rather than legacy network
enablement scripts.
In this case, install the NetworkManager package. In the non-nm case,
also install the network-scripts for Fedora 29 -- this has stopped
being installed by default (it's been deprecated since forever).
As noted in the docs, this is currently really only relevant on the
supported rpm distros which are using the ifcfg-rh NetworkManager
plugin to effectively re-use old config files. However,
NetworkManager has similar plugins for other platforms, so support can
be expanded if changes are proposed.

I'm not really sure why I originally had --logfile also log to stdout
in I202e1cb200bde17f6d7770cf1e2710bbf4cca64c, but it seem
counter-intuitive (indeed, I just tripped myself up thinking that in a
devstack job "--logfile" would put the logs into a separate file and
avoid the stdout logging, and I wrote it!).
Make it so specifying a --logfile puts dib into quiet mode for stdout.
Explicitly overriding DIB_QUIET will allow both if someone wants that.

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

The grub.cfg has two variables [1]
GRUB_CMDLINE_LINUX : used on all boots
GRUB_CMDLINE_LINUX_DEFAULT : additionally used on all "normal" boots
The problem with I2298675dda1f699c572b3423e7274bc8bd7c1c9d is that it
appened the values in DIB_BOOTLOADER_DEFAULT_CMDLINE to both of these,
resulting in duplicated arguments. I don't think we considered that
GRUB_CMDLINE_LINUX_DEFAULT actually already appends to the
GRUB_CMDLINE_LINUX values.
Make DIB_BOOTLOADER_DEFAULT_CMDLINE only append itself to
GRUB_CMDLINE_LINUX_DEFAULT. That seems to line up sensibly with the
name of the variable.

We added the DIB_distro_DISTRIBUTION_MIRROR arguments with
I92964b17ec3e47cf97e3a3091f054b2a205ac768 as a way that we could
source a list of mirrors and then have the distro elements choose
which one applied to them.
However, this hasn't worked out to be so useful. The
openstack-ci-mirrors element is working as a mirror setup script -- it
translates the openstack CI mirror list variables into the generic
"DIB_DISTRIBUTION_MIRROR" as appropriate for each distro's build.
Also, it turns out there's other things that need to be done, such as
turning off gpg checking, which mean the idea of "just export
variables" hasn't turned out as valid ... you need actual code
involved to get it right.
AFAICT we never actually documented these, and they do not seem to be
in use. They have caused considerable confusion when dealing with new
platforms as we try to keep consistency. Remove them.
