I manage 4 schools running ubuntu on their computers, we install via a PXE server and our in-house apt-cacher to minimize internet bandwidth. I also run a preseed file which automates the installation completely. This works perfectly if all devices have open-source drivers, but if i have a laptop with a wireless NIC with only a proprietary driver, i have to install it manually. How can i let ubuntu automatically install proprietary drivers?

PS. Where is there a forum to discuss the direction of ubuntu development? I see many things that can be improved in terms of automation and large-scale management, and would like to know what the devs think about it.

Best regards!
