Quick question, when you are applying patches to a production server do you stop the services (ssh, sendmail, nfs, etc) or do you keep the services running during updates? Thanks....

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Assume you refer to doing updates with the system package manager such as yum, then the answer is that you keep them running. The installation scripts that will run will shutdown and restart the services and unload/reload any drivers that were updated. The only time you need to shut down anything, is when you update the kernel and you want to start the system with the new kernel. In that case, you need to reboot.
    Sometimes, real fast is almost as good as real time.
