I'm running a small (but growing) Linux environment comprising of no more than 10 Linux servers.
The environment consists of CentOS 5 & 6, and Oracle Linux 5 & 6 boxen. All of these are patched individually via their appropriate yum repos.
Can anyone suggest a method of centralising patch management for these servers? I've heard that Puppet is often used to do this but I've never used it myself, and would be interested in hearing from other system administrators.
