If you have an existing configuration on **NixOS** or **nix-darwin**, the easiest way
|
||||
to switch to Lix is currently by using our provided _NixOS module_. Fortunately, this
|
||||
usually means adding only a couple of lines to your configuration.
|
||||
If you have an existing configuration on **NixOS** or **nix-darwin**, there are
|
||||
a couple of ways to switch to Lix, all of which are relatively easy.
|
||||
|
||||
- Using Lix from nixpkgs:
|
||||
- Potentially slightly older version of Lix
|
||||
- Working binary caching
|
||||
- Programs like nix-eval-jobs and colmena still use the default version of
|
||||
Nix (may be unacceptable depending on your use case)
|
||||
- Using the Lix NixOS module:
|
||||
- Fresh version of Lix right out of the freezer
|
||||
- You will be compiling Lix yourself, for now at least
|
||||
- Programs like nix-eval-jobs and colmena have the version of Nix they use
|
||||
overridden by an overlay such that most of the system uses Lix.
|
||||
|
||||
# Using Lix from nixpkgs
|
||||
|
||||
This approach has some caveats: since it is not using an overlay, it does not
|
||||
set the version of Nix depended on by other tools like colmena or
|
||||
nix-eval-jobs. Consequently, those tools will be using whichever version of
|
||||
CppNix is default in nixpkgs, likely leading to an inconsistent experience. It
|
||||
is, however, easy, and it does not take the few minutes to compile Lix from
|
||||
source.
|
||||
|
||||
Add the following code to your NixOS configuration:
|
||||
|
||||
```nix
|
||||
{ pkgs, ... }:
|
||||
{
|
||||
nix.package = pkgs.lix;
|
||||
}
|
||||
```
|
||||
|
||||
That's it, you're done.
|
||||
|
||||
You can verify that it works by running the following command:
|
||||
|
||||
```sh
|
||||
$ nix --version
|
||||
nix (Lix, like Nix) 2.90.0-rc1
|
||||
```
|
||||
|
||||
# Using the Lix NixOS module
|
||||
|
||||
The Lix NixOS module is the way to get the most consistent experience using
|
||||
Lix, and to have a system that has Lix as the default Nix implementation
|
||||
wherever possible by using an overlay to replace `pkgs.nix`. It will result in
|
||||
building Lix from source, which takes a few minutes on every update, which is a
|
||||
perfect time to get up, get some water, and stretch for a bit.
