If you have such a problem with Arch or rolling release in general. The simple answer is to not use it. No one is forcing you. And obviously you have some kind of problem with either or as you're nit picking and puposely seeking stuff to be wrong. Like I said in a previous post, you can go to any 'stable' distro's forums and find plenty of 'horror' stories alike. If you dig through Ubuntu, Debian, Red hat, Fedora, Slack, BSD, or any archive you can find 'spectacular failures'.
I don't use Arch (any more) so I don't really have a problem with it, nor do I care that people use it. Use what you like for all I care. All I'm doing is simply arguing the merits of the OS with people who think Arch is the bees knees and have started a discussion about how great it is.
