My experience with Arch has frequently been:

1. Run pacman -Syu

2. Pacman failed.

3. Go to Arch website

4. Learn that I shouldn't have run pacman just then, and now I have to follow these steps to un-break my system

The most notable instance was when Arch decided that /usr/lib should be a symlink to /lib. Yeah, barely recovered from that... it was also a reinforcement of my position that basic utilities should be statically linked.

I finally gave up on Arch when a GRUB update broke my system and locked me out of my encrypted root.
