see http://wiki.archlinux.org/index.php/User:Allan/Pacman_Hooks Before implementing anything, I would like to see the maximum of actions which are currently done in real package scriptlets converted to the new hook system. So that we are sure we have a good coverage. Scriptlets are just another case of code duplication which is my big enemy. Once we are confident enough that the proposed system achieves that, I think I would be interested and motivated to do the implementation.
