Hello James, I believe that MAAS 2.x's nodes-scripts (Hardware Testing and Commissioning scripts) might be helpful for any custom code or drivers you might want to inject in the commissioning process. Here is a link to the guide for these scripts. I might suggest the cript example for "Configure HPA" might provide a good template for how you might want to inject a Mellanox driver/config into your build. https://docs.maas.io/2.3/en/nodes-scripts The MAAS server has a web server serving out a docroot from /var/www/htdocs where you can drop any files you might want to curl/wget from your scripts. I believe there are environment variables for the preseeds for the IP of the MAAS server for your URL. You might also notice that you can have the script automatically install packages from any of apt, snap, or URL. You can even tag the script to automatically run on hardware with a specific PCI ID. with the for_hardware metadata field. Documentation on managing these scripts via the CLI is here: https://docs.maas.io/2.3/en/nodes-scripts-cli In MAAS 1 environments, one would have to update the curtin preseeds manually in /etc/maas/preseeds to inject scripts of this type. I do not know if the commissioning scripts also happen at deployment time (doubtful), but hopefully the install of your chosen OS will include the drivers needed, or you've found that you can add an Ubuntu package repository or PPA that contains your packages to be installed per https://docs.maas.io/2.3/en/manage-repos. I hope this information helps. Sincerely, -Drew
