The only way I know of is to do rolling updates- take certain servers = out of the farm, patch them, and then put them back in. One way to do this is disable new logins on target servers for a period of time before the = planned outage to reduce the number of users that would need to be knocked off. = If you have enough servers, you could make the period of time very long so = that there would no one logged in when the time came to patch and reboot.
