Each update reboots into the diagnostics partition and rewrites the entire root filesystem image, then reboots back into that image. (They used to ship patch releases that only modified the root filesystem, but they stopped doing that years ago, apparently in the belief that bandwidth is free everywhere and nobody could ever object to random 200MiB downloads...)
