- The page says saves are atomic incremental layers, while /tmp is deliberately emptied on every boot.
Field notes
The simulator’s described filesystem combines image layers with a writable overlay: writes copy up on first change, deletions use whiteouts, and saves commit a new layer. The page says these saves are incremental and atomic, with corruption checked at load. Its examples also make system behavior part of the lesson: /tmp is a real temporary filesystem and disappears on reboot, while recorded network responses can be replayed offline.
