summary
IncludeOS is a unikernel that performs atomic RAM update ~5 ms using full disk images managed by Mender.io so the live image is identical to what was tested locally, avoiding mixed-library states. Clients poll (demo uses a 10 s interval) and implement on_store / on_written callbacks to persist and restore app state across boot, while boot times are milliseconds (typical ~180–300 ms). Images are tiny—1.5–5 MB—the runtime is single-threaded C++/C friendly, and rollbacks happen by redeploying previous artifacts via the Mender server.
