<div dir="ltr"><div>Dear John,</div><div>thanks for your answer.</div><div>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:</div><div><br></div><div>- blacklist the nouveau</div><div>- reboot</div><div>- install the proper nvidia driver</div><div>- reboot again</div><div>- continue with software installation<br></div><div><br></div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>And this sequence, I think, cannot be fully automated with those scripts. <br></div><div>So I have been searching for a way to prevent the nouveau installation since the beginning.

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>
