This is only needed for direct loading by the kernel, which is
dangerous, and we include all the microcode in the initrd anyway.

The microcode was accidentally dropped from Flatcar a while back because
Gentoo started telling Dracut to not include it when USE=-initramfs.
Flatcar disabled that flag because the microcode is installed to /boot.
This is only done under the board root though, not in the final image,
so there's no harm in enabling it.
That Dracut setting also affected the AMD microcode, which is part of
coreos-firmware, so this fixes that too.

systemd-journal's Forward Secure Sealing feature requires gcrypt, but
Flatcar doesn't need it.

Dracut includes native binaries that are executed during the creation of
the initrd, so it always needs to be installed to /. For now, it expects
to find its modules in the sysroot, so it needs to be installed there
too, though that may change.
bootengine only needs to be installed to sysroot for its Dracut modules.
The update-bootengine tool is a Bash script, so it doesn't really need
to be installed to /.

This is code I have submitted upstream that has not yet been merged.
This also includes a small "catch up" patch from 106 to current main for
both a clean base and because these changes actually look important.

Flatcar can't benefit from this performance boost for several reasons,
the main one being the use of binary packages.

The final part of the script differed only the name of the qemu binary
to execute and in network device driver (virtio-net-pci on amd64 vs
virtio-net-device on arm64). virtio-net-pci seems to be working also
on arm64, so simplify the code to avoid repetition.
There's no need to differentiate between amd64 and arm64 boards here
any more. This also adds bootindex=1 option to the -device flag, so we
can pass more secondary disks without affecting the boot order.
This version writes fewer temporary files and tries cpio multiple times
for concatenated archives again.

Again, zstd is faster but we're getting seriously short on space. Unlike
the kernel itself, this applies to both amd64 and arm64.

zstd is faster but we're getting seriously short on space.
Unfortunately, the arm64 kernel still cannot be compressed, but it has
benefited from another space saving measure recently, and GRUB also
takes up less space in /boot.

We need this for dracut-install to have JSON support. It doesn't matter
that the Flatcar image will still have v256.

Updating only the SDK to systemd-257 caused this script to break, as it
saw this version being pulled in as a BDEPEND and then tried to build it
using the board profile. See the comment for details.
