Event for when computer is shutting down.

[BrisingrAerowing 12]

Is there an event fired when a computer is shutting down? I ask because I am working on a user roles system for SecureOS (using @payonel 's updated fork) and want to save the databases I use when the computer shuts down (they will also be saved on a timer).

Machine is stopped by calling computer.shutdown which is a "low-level" function brought to OpenOS from the bios environment. It becomes obvious that no event is fired when a computer is shutting down. You can override computer.shutdown to fire an event, wait for it to be processed, and then finally stop the machine.

OpenOS already fires an event called "shutdown" when computer.shutdown is called. Please don't override any system methods, nor add metatables to nor remove metatables from system libraries.

However, pressing the power button on the machine, losing power, or breaking -- do not send any such signal
