This script sends a kernel update alert email to users listed in the specified file and is intended to be run by a server node on the Thursday preceding the third Tuesday. Because cron does not directly support this kind of scheduling, the script runs every day between the 10th and 16th and exits quietly on all days except Thursday (day 4).

This script updates the kernel then reboots the node. It is meant to be started by cron just after midnight on the third Tuesday of the month and preceded by an alert email on the prior Thursday. Because cron does not directly support this kind of scheduling, the script is run each day of the third week and tests for Tuesday (day 2) and exits quietly on all other days.
