At work I have two Ubuntu and two CentOS servers. What do you recommend as the best practice for applying updates? Specifically, do you do any testing on test machines first, or just wait until the updates are a certain age without hearing of any issues? Automatically apply them, or manually? Do you reboot the servers regularly regardless of whether you've patched them (something Windows administrators still do for their Windows servers!), or just wait until a kernel or other update requires it?<br>
