This change introduces bake_flatcar_image.sh, a standalone script for creating Flatcar OS images with sysexts (from the bakery and other sources) included.
The script will download a generic Flatcar OS image (version can be specified), copy local sysexts into root or OEM partitions, and create respective symlinks to /etc/extensions.
By default, the script operates on local sysext files. However, the --fetch option may be specified to download sysext(s) from the latest Bakery release.
Optionally, vendor images can be created. If requested, the script will use the Flatcar SDK corresponding to the OS image version to generate vendor images from the generic image.
Then loopback-mount flatcar_production_image.bin (partition 9) to verify.
To build a bootable image, use
wget https://github.com/flatcar/scripts/commit/28070022226970ff3e819516a60721d8648a0f23.diff
./bake_flatcar_image.sh --vendor qemu wasmtime:wasmtime-17.0.1-x86-64.raw
# AFTER THE SDK WAS CHECKED OUT, in a separate terminal window, run
cd flatcar-os-image

# after the build concluded, run

Testing done
Built wasmtime qemu_uefi OS images for x86-64 and arm64, both root and oem partitions, booted and tested wasmtime.
Built ami and azure vendor images but didn't test.

NOTE that building vendor images requires https://github.com/flatcar/scripts/pull/1682 . To test, apply https://github.com/flatcar/scripts/commit/28070022226970ff3e819516a60721d8648a0f23.diff right after the script checked out the
scriptsrepo (can be done in parallel because the script will spend some time downloading SDK container and OS images before continuing).How to use
