[RndTbl] Linux patching best practices

[Kevin McGregor]

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?
