[arch-general] Pacman trigger

[Nilesh Govindarajan]

Is there some app that will do some actions on updating some software ?

Like for example, I want that in 
/usr/lib/firefox-<version>/defaults/preferences/firefox.js user agent is 
set to Firefox/<version> instead of its brand name ?

Or copy the previous version of kernel to /boot/stable before update ?
