A failure to reach the control node can cause slurmd to fail and the
unit remains in the failed state until is manually restarted. Instead,
try to restart the service every 30 seconds, forever:
owl1% systemctl show slurmd | grep -E 'Restart=|RestartUSec='
Restart=on-failure
RestartUSec=30s
owl1% pgrep slurmd
5903
owl1% sudo kill -SEGV 5903
owl1% pgrep slurmd
6137
Fixes: #177

The StartLimitBurst and StartLimitIntervalSec options belong to the
[Unit] section, otherwise they are ignored in [Service]:
> Unknown key 'StartLimitIntervalSec' in section [Service], ignoring.
When using [Unit], the limits are properly set:
apex% systemctl show power-policy.service | grep StartLimit
StartLimitIntervalUSec=10min
StartLimitBurst=10

The cudainfo program checks that we can initialize the CUDA RT library
and communicate with the driver. It can be used as standalone program or
built with cudainfo.gpuCheck so it is executed inside the build sandbox
to see if it also works fine. It uses the autoAddDriverRunpath hook to
inject in the runpath the location of the library directory for CUDA
libraries.

This allows running derivations which depend on cuda runtime without
breaking the sandbox. We only need to add `requiredSystemFeatures = [ "cuda" ];`
to the derivation.

These sensors are part of their air quality measurements, which just
happen to be very close to our server room.

Allows us to track ambient temperature changes and estimate the
temperature delta between the server room and exterior temperature.
We should be able to predict when we would need to stop the machines due
to excesive temperature as summer approaches.

The current select mechanism was using the memory too as a consumable
resource, which by default only sets 1 MiB per node. As each job already
requests 1 MiB, it prevents other jobs from running.
As we are not really concerned with memory usage, we only use the unused
cores in the select criteria.

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.
