notification of system reboots

[Chandler A. Collins]

Actually, we've had similar mechanisms in place in the past, but we're trying to find a clean way to use Nagios to handle this task that won't involve the installation and maintenance of a separate script.  We already have to add a new host to a specific hostgroup in Nagios to make sure all the right services are being monitored.  We'd like to make it so that notification of a system reboot is simply part of the suite of services that are being monitored under this hostgroup.
