I am looking for a way to assure that all Redhat boxes have same packages and configuration. For example, when I add new server, it is configured and the packages installed.
Same for Ubuntu.
I can make manually script which will replicate the master server, but I need to know if there is any other solution to accomplish this in a way that clueless operator can handle it, or it's fully automatic without need of command-line.
On Windows, I use Domain Controller, it works OK - it configures and updates all systems. I have only two Linux boxes, hence the issue is not big versus hundreds of Windows ones, but eventually I will scale the setup globally, so I need to prepare some plan for Linux too.
