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
