Also have a copy of pacman-static somewhere so that you can fix your shit in case of a partial upgrade (and trust me, it can go horribly wrong)
And thirdly, Arch is meant as a power user distro -- despite this abhorrent popularity it has gained, the fact of the matter remains that you need to know the system inside and out, if you make your arch system unable to boot..... Don't use arch
This is not my attempt at elitism. Arch was never meant to be a hassle free distro and it sure as shit is not one.
There are many maintenance-free distros you can use instead. Can I offer you a Debian in these trying times?
