The "billions of years" is stable running time.
Well, stable is certainly a matter of opinion.
No, definatly stable, GOD has never had to ALT CTRL & DEL. Mind you he did have to do a clean insatall, and had to wipe nearly everthing (He did save a couple of templates of everyting tho). However that wasnt his fault, it was because on the original instal a virus/worm had gotten in, and currupted a couple of higher systems. Well, stable is certainly a matter of opinion.
I suppose your talking about the problem with the firewall that he tried to instal? True the virus checker did kill it, but it was OK cos a deep backup existed, and it was able to re-install itself within three working days.
