[arch-releng] mkarchiso feature request

[Mr Green]

I am currently loading xorg-driver group packages from a package list, 
overnight thought about adding ignore package to pacman.conf but now get

xf86-video-intel-sna is in IgnorePkg/IgnoreGroup. Install anyway? [Y/n]

Of course this means

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: xf86-video-intel-sna and xf86-video-intel-uxa are in conflict

Is there a way or possible addition of a feature that will take notice 
of any packages I do not want installed?
