说明
steamos-update updates SteamOS to the latest available version on the selected branch. Updates are downloaded and installed to the inactive A/B partition, then the system reboots to the updated partition. The A/B partition scheme ensures a reliable fallback if an update fails - the previous working partition remains available for recovery. steamos-update returns exit code 0 when an update was applied or is available (depending on subcommand), and 7 when the system is already up to date (useful for scripting).
