systemd system extensions for Centos image based systems

NOTE: This is currently an experimental project. Make sure to read the known limitations section. Use at your own risk.

For usage instructions, see the documentation at: extensions.ketelsen.cloud

Building

Building those images currently require root privileges. The currently supported options for building those sysexts are:

• using a rootless, privileged, non-SELinux confined container (such as a toolbox/distrobox container), redirecting podman commands to run them on the host:

  [toolbox]$ cat /usr/local/bin/podman
  #!/bin/bash
  executable="$(basename ${0})"
  exec flatpak-spawn --host "${executable}" "${@}"
  

• Using nested podman containers (current path in CI).

Make sure that you have the following packages installed:

• cpio
• erofs-utils
• jq
• just
• podman (only when not using the host redirection script above)
• wget

To build the python sysext:

$ cd python

List the supported target images:

$ just targets

Build the sysext for Fedora CoreOS next:

$ just build "quay.io/fedora/fedora-coreos:next"

extensions.fcos.fr redirector

A Caddy based redirector is hosted at extensions.ketelsen.cloud. The configutation is available in Caddyfile. It redirects URLs queried by systemd-sysupdate to GitHub releases where the sysexts are hosted in this repo.
