On Windows, the .bz2 compression format is not supported by native
tooling and external tools like 7zip need to be installed.
Switching to .zip compression, there will be no need for the extra step
of having external tools.

So far the console in OpenStack (or Brightbox which shares the image)
was not usable well until one issues a reboot to add the autologin in
the GRUB menu.
Add it by default so that one doesn't need this reboot trick.
The qemu and qemu_uefi_secure images have the same contents as the
qemu_uefi image which wastes space on the release server. A similar
case is the PXE vmlinuz which is the same as the regular one, too.
Set up symlinks for same images, and also detect this when compressing
to set up symlinks there as well. To reduce complexity, the qemu and
qemu_uefi_secure images are not supported anymore and the Jenkins or
GitHub CI will skip over them if specified. Users that build their own
images need to adapt, though.
Add support for Gen 2 Hyper-V VMs.
`./image_to_vm` tool has now a new supported format: `hyperv_vhdx`,
that produces .vhdx dynamic disks.
How to use:
```bash
./image_to_vm.sh --from ../build/images/amd64-usr/developer-latest/ --format hyperv_vhdx
```

While Flatcar itself runs fine with 1 GB, many workloads do not and
having to debug this is time consuming when one forgets to bump the VM
memory, e.g., in the Qemu script.
Default to 2 GB as known-good setting for things like Kubernetes or
setting up LUKS devices.
The 5.6 release contained a backdoor for SSH. The 5.6 release wasn't
used in Flatcar and so far it seems that the backdoor wouldn't even be
compiled for Gentoo. However, we so far don't know whether the other
patches are malicious.
Revert to 5.4.2 as last known-good release (like Gentoo did).
Note that the Flatcar main branch had a copy of the 5.6 ebuild but was
not using it. Flatcar Alpha was on 5.4.6-r1, so before the backdoor but
the malicious contributor did other changes of unclear impact part of
this release. Similarly, Beta is on 5.4.5 and Stable is on 5.4.3. These
should get downgraded, too.
This change updates coreos-cloudinit to the latest flatcar-master commit.
This change disables user-configdrive.service on OpenStack,
as coreos-cloudinit.service already runs on OpenStack when the system is
not configured via ignition.

The Flatcar extension images built with build_sysext created directories
in the overlay in a way that masked contents from other layers.
Instead of fixing the way we create directories, make use of
postprocessing to avoid any similar problems show up again in the
future.
