20200726 After an upgrade there may be times when a reboot is required (such as when the kernel is upgraded). We can check if a reboot is required by checking for the file /var/run/reboot-required. If it exists then the computer requires a reboot and the contents of the file may explain why. Wajig can do this check:
$ wajig reboot *** System restart required *** To reboot use "sudo reboot"
To reboot a computer usually requires admin privileges, hence the use of sudo with the reboot command. Wajig itself will not reboot the computer.
