Re: [Nix-dev] ioquake3 on nixos

[Máté Kovács]

Hi all,

I made a small improvement to the derivation for playing the game:

{ nixpkgs ? import  { } }:
with nixpkgs.lib;
let
  paks = nixpkgs.stdenv.mkDerivation {
name = "quake3-arena";
sources = sourceFilesBySuffices ./baseq3 [".pk3"];
buildCommand = ''
  install -D -m 644 $sources/* -t $out/baseq3/
'';
  };
in nixpkgs.quake3wrapper {
  paks = [ paks nixpkgs.quake3pointrelease ];
}

This will copy all pk3 files to the destination baseq3, which comes in
handy if you have custom maps and mods.

(In case you're wondering: I didn't yet figure out what's wrong with my
channels, so I'm pointing to a clone of the nixpkgs github repo using the
-I option for building the game.)

Cheers,
Mate

[Nix-dev] Synchronizing a the binary cache

[Evan Rowley]

Hello,

I am wondering if it is possible to somehow synchronize a machine with the
nix binary cache, so that on a separate network, it may service NixOS
client requests to download binaries.

I'm interested in any other tips / guides on using NixOS on networks with
limited or no connectivity to the internet.

I don't use NixOS at the moment, but if this were possible, then it would
bring me one step closer towards using it. My home internet connectivity is
extremely unreliable due to it's remote location, so am looking for a way
to cache packages and other necessary things locally.

The OS I use the most now is FreeBSD and it is simple to cache packages and
binary sets used to perform installations.

Hi Nix'ers,

This is an Nix Ops related question.

How can I specify which channel to use inside the nix expressions (*.nix
files) for nixops?

Thanks in advance!
