=== Declarative Configuration ===

The only configuration file officially associated with Nix is <code>nix.conf</code> (usually found in <code>/etc/nix/</code>), which defines a number of settings relating to how Nix, including build, garbage collection, sandboxing, and user permissions. Details on the available options are found in the [https://nixos.org/nix/manual/#sec-conf-file|nix.conf section of the manual].

~~Work~~ on ~~Nix user profiles~~ is ~~well underway, see {{pull|9250|PR 9250}}~~.

[[Home Manager]] is the preferred way to manage declarative environments for a single user.

For system configuration on macOS [https://github.com/LnL7/nix-darwin nix-darwin] is the preferred solution.
