    Why is it a class though?

      What’s the problem?

      Any NixOS user can tell me if the only way to have the latest version of everything is to use the unstable channel? Basically I want Arch but with an easy undo button so I don’t look like a fool at work when upgrades go bad.

        I’m an Arch -> NixOS convert and run unstable, it’s basically what you’re looking for.

          Thanks you very much.

          Even better, you can run stable, but then manually pull unstable packages out and install them. I ran 17.09 but pulled in the unstable LLVM 6.0 for example. The same would work for firefox/chrome or other packages.

          for example:

          let
          unstablePkgs = import ((import <nixpkgs> { }).fetchFromGitHub {
            owner = "NixOS";
            repo = "nixpkgs";
            rev = "Some future unstable nixos version with a version of firefox you want";
            sha256 = "XXX";
          }) { config = { }; }
          in
            unstablePkgs.firefox
          

          If you paste that into a file default.nix and run “nix-build” (or now in this release “nix build”) it will give you exactly the right firefox like magic you can also install it into your user profile with nix-env -i.

          edit: Or what you could do, is run unstable, but pull in old packages from the past if you don’t want the new one.

            like magic

            that is also my experience in using nix.

              That’s a super easy way to do it. If you wanna add unstable and have a tool track the commits, you can use nix-channel, add it then install it via nix-env and a prefix.

                True, I have never tried having multiple channels, but it works too.
