After thinking/discussing on irc. I agree that this is the best
solution. I'll post a patch which just implements the super simple
case I just posted earlier, and then people can extend it if they
want.

I think the most important thing is that we declare separate /usr
unsupported, so we stop getting bug reports, and we can start
simplifying PKGBUILD's.

People can use this or similar hooks if they are not able to merge /usr and /.

Cheers,
