Usage instructions

First time setup

Run those commands if you have not yet installed any sysext on your system:

sudo install -d -m 0755 -o 0 -g 0 /var/lib/extensions /var/lib/extensions.d
sudo restorecon -RFv /var/lib/extensions /var/lib/extensions.d
sudo systemctl enable --now systemd-sysext.service

Installation

Define a helper function:

install_sysext() {
  SYSEXT="${1}"
  URL="https://extensions.fcos.fr/extensions"
  sudo install -d -m 0755 -o 0 -g 0 /etc/sysupdate.${SYSEXT}.d
  sudo restorecon -RFv /etc/sysupdate.${SYSEXT}.d
  curl --silent --fail --location "${URL}/${SYSEXT}.conf" \
    | sudo tee "/etc/sysupdate.${SYSEXT}.d/${SYSEXT}.conf"
  sudo /usr/lib/systemd/systemd-sysupdate update --component "${SYSEXT}"
}

To update all sysexts on a system:

for c in $(/usr/lib/systemd/systemd-sysupdate components --json=short | jq --raw-output '.components[]'); do
    sudo /usr/lib/systemd/systemd-sysupdate update --component "${c}"
done

uninstall_sysext() {
  SYSEXT="${1}"
  sudo rm -i "/var/lib/extensions/${SYSEXT}.raw"
  sudo rm -i "/var/lib/extensions.d/${SYSEXT}-"*".raw"
  sudo rm -i "/etc/sysupdate.${SYSEXT}.d/${SYSEXT}.conf"
}
