If you boot a Fedora 22/23 machine with root on btrfs, you get something similar, I believe: dnf notifies you of OS upgrades, you click 'yay', the system reboots, makes a snapshot and installs upgrades. If installation fails, the snapshot is rolled back; if it completes successfully, the system reboots again and you're good to go. It's apparently been in since systemd 183: https://wiki.freedesktop.org/www/Software/systemd/SystemUpdates/ https://wiki.freedesktop.org/www/Software/systemd/SystemUpda...
