Portable Linux gaming with the Steam Deck
The release of Valve's Steam Deck brings a new release of SteamOS, complete with a brand new A/B design for seamless system updates.

When not using Windows makes updates much more stableWith its new “A/B” design, there are now two operating system partitions, with two different versions of SteamOS. When upgrading, a new operating system image is written to whichever partition is not currently in use, before rebooting the system. A specialized bootloader module then automatically selects the newer operating system and boots into it. If the upgrade was successful, you continue to use the new OS, and the previous system partition is reused for the next upgrade. If the upgraded version does not boot successfully, then the bootloader automatically falls back to the previous system partition, and you can try again later. Of course, new operating system images are downloaded with block-based deltas, so only the changed parts need to be re-downloaded.
