systemd-sysext provides a nice way to enhance a distribution with a read-only root filesystem without the need to reboot. But there is additional tooling necessary to manage the sysext images: * install an image which is compatible with the installed OS version * update installed images to the newest compatible version * rollback images in case of an OS rollback * cleanup unneeded images In this presentation I will talk about which tooling systemd itself provides for this (importctl, updatectl, ...) and what the benefits and disadvantages of this tools are compared with real world use cases. In the end I created an own, generic and distribution independent tool for this using systemd tools in the backend. Using openSUSE MicroOS as example I will demonstrate how we solved the problems with it and how we integrated it in our update stack.
