The background is a headless installation on bare metal with manual updates. The box is offline and is
only accessible via dedicated (private) network.
Because the box would then not consume the official Fedora updates, I want to have a reliable mechanism to rollback in case of failing updates. Therefore I want to add greenboot in conjunction with bootloader adaptions (actually the stuff which is on current Fedora IoT).
I am just experimenting with the stuff, and maybe Fedora IoT at the end could match better, but I like the idea of coreos to be container focused and one day, the box maybe also would move to the cloud.
