[arch-releng] Removing packages from archiso

Hi, I am trying to build an iso that includes LTS kernel at the moment I can add linux-lts to package list. Need a clean way to remove linux [kernel]. Thinking along the lines of adding a 'pacman -R' to mkarchiso, possibly adding something like _pacman () maybe _pacman_remove(). Not sure it will be a possible patch as it may be of any other use to anyone. Ideas are easy creating them is a different story Mr Green
