Current situation

Currently, there is no documentation on how to use the built-in Sysext images except some Butane snippet or sharing configuration used in the CI.

Impact

It makes harder to discover the existing images and how to easily deploy them on Flatcar.

Ideal future situation

Supported extensions listed in the documentation + Butane / Ignition example to deploy it + a simple example to get started with the extension: if it takes some specific additional configuration, etc.

Implementation options

It could be under the "Provisioning Tools > Systemd sysext" section.

  • Docker
  • Containerd
  • ZFS
  • Incus

Great idea, we could also make this section more generalised about "extending the base OS system" (if only by header, for a start). The bakery also offers pre-baking images, we should cover this too: https://github.com/flatcar/sysext-bakery/?tab=readme-ov-file#baking-sysexts-into-flatcar-os-images

As discussed in flatcar/Flatcar#1409
the page on systemd-sysext images should also cover the customization
of release images by putting extensions into the rootfs.
Instead of having duplicate content that we need to keep up to date, add
a reference to the systext-bakery README.
