Fedora Core 2 included it. IIRC it was set to permissive mode or disabled. I can't remember which. But I'm not sure what the significance of your "correction" is other than to prevaricate, since the SELinux nightmare did begin in earnest in Fedora Core 3. (I recognize a tactic that you have employed previously.) It was only in FC6 that users were even provided the tools to fight SELinux effectively. Does the fact of its introduction being in FC2 or FC3 really make a difference today, 4 years later?
