I have to agree with pyther. You, devs, have been doing all you can to warn the users. There is the arch-announce mailing list, there are messages from pacman when it installs something that might break others, there is the forum, there are announcements on Arch's home page... Damn! there are even RSS feeds! Even though, many users will complain, just like when X got updated and HAL needed to be running. IMHO, you should say "We're sorry, but we did try to warn you". I mean, what else could you do? Call every user and tell them that there'll be a big update? You're doing a great job, don't let the few people from the Arch community that don't know how to read upset you.
