I recently installed CentOS 6 Minimal distribution on my old Dell desktop. CentOS Minimal only weighs in at 396MB and is a basic installation. It’s so basic that no X windowing and networking is not configured. However, SELlnux is included and in Enforcing mode…cool! This system is dedicated to automated notifications via scripting. Actually, I’ll probably release a few homegrown web-based applications.
The most “GUI” thing you’ll see in this installation, is the startup status bar (see below). If you want to play on this system, leave your GUI skills behind, cuz it’s all command line here.
