caleb [1] filed a deletion request for aurto [2]: Package was recently deleted for performing user specify stuff in hook scripts. All that got moved out of the PKGBUILD and instead just stuffed into an upstream script that is still triggered. This does things like editing the system pacman.conf and deleting files in etc that aren't tracked by the package itself on pre_remove().
