Select proprietary NVIDIA driver in raccoon
...
The NVIDIA GTX 960 from 2016 has the Maxwell architecture, and NixOS
suggests using the proprietary driver for older than Turing:
> It is suggested to use the open source kernel modules on Turing or
> later GPUs (RTX series, GTX 16xx), and the closed source modules
> otherwise.

Add proxy configuration for internal hosts
...
Access internal hosts via apex proxy. From the compute nodes we first
open an SSH connection to apex, and then tunnel it through the HTTP
proxy with netcat.
This way we allow reaching internal GitLab repositories without
requiring the user to have credentials in the remote host, while we can
use multiple remotes to provide redundancy.
