emerge-gitclone was never GPL-2.0, it was BSD-3. We're switching it to
Apache-2.0 with this commit.

'norecovery' was deprecated and has been removed in kernel v6.8 so switch to
the new way of doing things.
This pulls in https://github.com/flatcar/update_engine/pull/40.

Putting things in a sysexts subdir results in the same layout on
bincache and does not follow the expected url schema for fetching the
sysext.

Gentoo's linux-info.eclass tries to check the kernel version by
including /lib/modules/.../source/Makefile and printing $(VERSION). It
unsets ARCH= before doing this (no clue why) which works with a full
source tree but not with our minimized one. To fix this we need to
archive arch/x86/Makefile also for arm64.

This allows it to be sourced from other scripts and used e.g. in
generating an image changes summary.

There are two challenges with the sysext: it needs config files in /etc
and it needs udev rules for mounting during boot to work. The etc files
are placed in the standard flatcar etc overlay path but the overlay is
mounted from the initrd. So instead, we create a tmpfiles.d rule that
symlinks the best important files over. For the udev issue, we create a
drop-in in /etc that ensures udev runs after systemd-sysext.
We also can't rely on systemd presets to work, so instead parse the
preset file and statically create the service dependencies. For the
primary zfs.target we rely on an Upholds entry. Users can still disabled
unwanted services if they want.
We also removed unnecessary files:
- development files
- initramfs related scripts

The zfs-kmod ebuild needs KERNEL_DIR to point to the correct
/lib/modules directory.
The zfs ebuild installs two systemd unit masks to /usr/lib/systemd which
result in "dangling symlink" errors during the image build. These
systemd unit masks are only necessary for old Ubuntu systems that have
sysv-init-systemd compat wrappers.

We explicitly install gawk but our profile explicitly forces the gawk
useflag for app-alternatives/awk. Some packages, like zfs, depend on
app-alternatives/awk and it also installs the awk -> gawk that the gawk
ebuild creates through pkg_postinst. So switch to app-alternatives/awk
to make the implementation cleaner.

build/source, which is accidentally an empty directory, needs to be a
symlink so that Gentoo kmod ebuilds can build when setting
KERNEL_DIR=/lib/modules/.../build. They detect the proper layout with
the symlink.
The other issue is building the Nvidia driver with
SYSSRC=/lib/modules/.../build. This works on Ubuntu but fails on
Flatcar. Ubuntus build directory contains symlinks to includes from the
source tree so recreate the same layout.

by skipping the check for an existing image directory if we're not
building an image. This makes './build_image sysext' work.

This function is meant to prebuild certain sysexts to be released along
with each release. These will not be built into the image, but instead
can be fetched by the user on demand.
The command to build sysexts would be:
./build_image prod sysext

It looks like 'norecovery' is deprecated and has been removed in the v6.8-rc1
kernel. Replace it with 'rescue=nologreplay', which is a replacement
implemented since v5.9. The standalone 'nologreplay' option is also deprecated.

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.
The PXE image and its helper script is a very handy way to test an image
because it does not preserve state. One can boot the same file over and
over again without having to reset the image. One can also easily pass
in additional kernel cmdline options without having to set up grub.cfg.
