alternate grub.conf?

Rapid reboot :)

Showing rebooting notifications in lightdm / unity greeter

[Alec Warner]

We use the reboot-required file and the freedesktop notification
framework to notify users that they should reboot.

Users have requested that we show a notice at login time (before they
login and start working.) Does anyone know if such a notification is
