You don't have to use it if you choose not to - it's your prerogative. It's just an additional layer of security. Lastly, just because you showed little ability to learn the new tools to live peaceably with software that is ignorant of the security implications of an important tool set for security, doesn't make it bad. There are a lot of things that you do on a computer that I would surely not recommend to others - such as this suggestion to append selinux=0 to the kernel boot line as opposed to setting selinux as disabled (and there have been others as you know). As for Rahul, Steve Smalley and you going around on an issue...I would take their side every time, without the slightest bit of hesitation. Craig
