A few days ago, I got a mail from Microsoft saying it wanted to load updates and reboot one of my systems. It had a "button" to poke to delay this act which I pressed. I had a job running, which had been grinding through a number set for days and was showing 80% complete. The next day, it popped up again, but this time, no way to back it off again, it simply said it was rebooting in 5 minutes, save and exit. It did, and I lost my work, two weeks of work. Do Linux distros ever do this?
