This is an alternative approach to commit
68bb43535e. I think this proposes a
better overall solution that the prior change which had the Python 3
packages being installed, but did not specify the _do_py3 flag to do
the installation steps that redirect the various tool installations.
Fedora 31+ doesn't have python2, and Tumbleweed does have some Python
2 support but there seems to be no reason to bother updating this
element for either with infra very close to removing this completely
[1]. Error out on these platforms, and add a release note.
The 15 path should include the python2 and python3 packages, along
with the flags to do the "cleanup"; i.e. forced removal of distutils
packages that pip 10+ won't touch. As mentioned in the original
change, the six package causes problems here, but we can clear that
too by explicitly listing it instead of letting it come in via
dependencies. Again, this element will be removed from the infra 15
builds ASAP; but we can release with this to provide a roll-back point
if we need to revert the removal to fix things temporarily.
Add it to the testing path as well.

All the platforms we care about now have python3 with venv (even
centos7 now) packaged somehow. Add an ensure-venv element to make
sure that "python3 -m venv" works. Any other elements that wish to
install non-distribution-packaged Python utilities can use this to
keep them separate from the main system installs.
Port glean to use this, and drop its dependency on pip-and-virtualenv.

The current implementation evauates the dib-init-system
script too early. Also it looks that there is no simple
way of getting the info about the init system automatically:
another element can install (later on) a different
init system. Therefore the only reliable way of setting
this is manual.

The vhdutil utility is completely dead; the whole subsystem it relies
on was removed with [1] so it's not even vaguely possible to keep it
up-to-date.
I took the .raw images on a nb and used the qemu-img there (so Xenial)
and generated some VPC images; uploaded them to rackspace and the all
seemed to boot fine. If there was a problem, maybe it's been fixed on
either the qemu or RAX side in the previous few years.
Thus swith to qemu-img to generate the vhd images too.

NetworkManager with simple-init has proven to be stable in OpenStack
infra, switch to it by default for CentOS and Fedora. For CentOS 8
and Fedora, add a check to make it the only option. Thus only CenOS 7
remains optionally using the legacy scripts; this is likely not used
anywhere (infra is really the primary user, where NetworkManager is
already used); we can likely remove this variable (and hence path) in
a future cleanup.

As described inline, deprecate the "source" install for CentOS 8.
Overwriting the packaged tools has long been a pain-point in our
images, and the best outcome is just not to play the game [1].
However, the landscape remains complicated. For example, RHEL/CentOS
8 introduces the separate "platform-python" binary, which seems like
the right tool to install platform tools like "glean" (simple-init)
with. However, platform-python doesn't have virtualenv (only the
inbuilt venv).
So that every element doesn't have to hard-code in workarounds for
these various layouts, create two new variables DIB_PYTHON_PIP and
DIB_PYTHON_VIRTUALENV to just "do the right thing". If you need is
"install a pip package" or "create a virtualenv" this should work on
all the platforms we support. If you know more specifically what you
want (e.g. must be a python3 virtualenv) then nothing stops elements
calling that directly (e.g. python3 -m virtualenv create); these are
just helper wrappers for base elements that need to be broadly
compatible.

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 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.

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.
