I run a student operated server, and I inherited an ancient Debian install that I had little control over. I proceeded to wipe for FreeBSD9 (partially the decision of the operator just before me), had that for about six months. Now that I am on Debian Testing again, life is simple again. I appreciate this about Debian.
But given the nature of the 'student' part, I cannot have a compiler that is ancient considering the C++11 stuff people are using. Even in testing it is a great system.
