 Innen 24h skal alle systemene hente ned den nye konfigurasjonen og deploye den.

 Du kan tvinge en maskin til å oppdatere seg før dette ved å kjøre:
-`nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git --upgrade`
