I've noticed that while the Webmin update notification system works reasonably well, there are a couple of curious omissions: information shown when logging in to the Ubuntu terminal, that is not shown anywhere in Webmin. Specifically, the "restart required" and "new release available" messages.
Is there a Webmin setting I've overlooked? Is there a technical reason why Webmin can't show this information?
My own research revealed this: "The shell script /usr/share/update-notifier/notify-reboot-required updates /var/run/reboot-required and /var/run/reboot-required.pkgs." Could this information be added to the System Information page?
