The raccoon workstation has a Nvidia GTX 960 GPU which will be used for
CUDA experiments. The configuration uses the production Nvidia driver
at version 550 which still supports the GPU. The current CUDA 12.2
version is also supported by the driver.
The workstation has Internet access directly from the gateway, but name
resolution via Google DNS servers seems to be blocked, so we use BSC
servers for now.
The NixOS system is installed in a partition alongside the old Debian
system, until we decide that is no longer neccesary to keep both. The
old /home partition is not used as we are using the same UIDs and groups
from the xeon machines, which don't match the ones here.
To accomodate the raccoon knights workstation, some of the configuration
pulled by m/common/main.nix has to be removed. To solve it, the xeon
specific parts are placed into m/common/xeon.nix and only the common
configuration is at m/common/base.nix.
The users.jungleUsers configuration option behaves like the users.users
option, but defines the list attribute `hosts` for each user, which
filters users so that only the user can only access those hosts.
The /tmp directory was using the SSD disk which is not erased across
boots. Nix will use /tmp to perform the builds, so we want it to be as
fast as possible. In general, all the machines have enough space to
handle large builds like LLVM.

This is done to prevent accidental evaluations where the nixpkgs input
of bscpkgs is still pointing to a different version that the one
specified in the jungle flake. Instead use jungle#bscpkgs.X to get a
package from bscpkgs.
