<p class="MsoNormal" style="margin-left:35.4pt">Putting a script in the /srv/fai/config/scripts/ is the way I was trying but, if the system boots with the nouveau driver already installed, the sequence to install correctly the new one is:<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:35.4pt">FAI works a lot like an installation you'd do "by hand". You boot from a
<br>
live image, partition the hard drive, install a base system via <br>
debootstrap then chroot to do the rest of the installation steps <br>
(install a kernel, install packages, configure grub). So, if you want to <br>
blacklist a module, you have to do it on the new system, not on the live <br>
boot image. In other words, in your case, you'd have to fcopy the module <br>
configuration files to the new system after the base system is <br>
installed. This is done by putting a script in the scripts folder of <br>
your FAI config root. By default this would be /srv/fai/config/scripts/.<br>
