How to gracefully shutdown scripts running through forever on OS reboot?

Question

linux

Greetings. Question to those who use forever.
In general, it is clear that in my case, forever should be started with --killSignal=SIGTERM.
Then, forever stopall will send SIGTERM to the scripts, and there, in the signal handler, I do everything I consider necessary before calling process.exit ().
But! If there is a reboot of the OS, then it does not work?

Answer 1

and forever stop you do before reboot?
