Driver replacement

FAI works a lot like an installation you'd do "by hand". You boot from a 
live image, partition the hard drive, install a base system via 
debootstrap then chroot to do the rest of the installation steps 
(install a kernel, install packages, configure grub). So, if you want to 
blacklist a module, you have to do it on the new system, not on the live 
boot image. In other words, in your case, you'd have to fcopy the module 
configuration files to the new system after the base system is 
installed. This is done by putting a script in the scripts folder of 
your FAI config root. By default this would be /srv/fai/config/scripts/.
