What is the schedule for applying patches to Linux machines in CS?

Each machine in the CS department that is running Linux is set to download and install patches that Redhat/Fedora deems critical (in other words, security related), as well as other upgrades to the OS or patches for other programs that Lab staff deem important. Patches will be downloaded as they become available, and every Wednesday morning at approximately 4:00 am, each computer running Linux will install any new patches that have been downloaded. If any of the patches requires a reboot, the machine will reboot when the installation is completed.
