 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`
+`nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --upgrade --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git`
 
 som root på maskinen.
 
+Hvis du ikke har lyst til å oppdatere alle pakkene (og kanskje måtte vente en stund!) kan du kjøre
+
+`nixos-rebuild switch --override-input nixpkgs nixpkgs --override-input nixpkgs-unstable nixpkgs-unstable --flake git+https://git.pvv.ntnu.no/Drift/pvv-nixos-config.git`
