Hello Pasquale, if your compute nodes are identical and all of them need the Nvidia driver, you can use a basefile that already has Nouveau removed and Nvidia installed. Then there is no need for a Nvidia installation script at all.
Just as an unconventional idea… Best, Frank -- Frank Morawietz Von: linux-fai <[email protected]> Im Auftrag von Pasquale Cantiello Gesendet: Donnerstag, 25.

If you are unsure please click the button "Report suspicious email" Dear John, thanks for your answer. 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: - blacklist the nouveau - reboot - install the proper nvidia driver - reboot again - continue with software installation And this sequence, I think, cannot be fully automated with those scripts. So I have been searching for a way to prevent the nouveau installation since the beginning. I will study the fai-scripts in order to better understand how this happens. Best regards Pasquale --- ing.

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/.
