Add a new setting to the update manager specifically for SysAdm:

"auto_update_reboot" = "0"-"23" (hour of the day)
If this is set (to a valid number), then SysAdm will automatically reboot the system to finish performing updates at the specified hour. Any other setting (or the value not being set) disables this option.
