If with this you mean requiring a restart then arent' you wrong? Ubuntu is linux, right, so it's an operating system, and it has stuff like /var/run/reboot-required.pkgs so it's not like all linux flavors out there don't ever require reboots. If you meant forced restarts at a given time (or whatever windows 10 does) then you're right. For now, and hopefully forever.
