# By default, NixOS will try to refer the nixosConfiguration with
# its hostname, so the system named `nixos-test` will use this one.
# However, the configuration name can also be specified using:
# sudo nixos-rebuild switch --flake /path/to/flakes/directory#<name>
#
# The `nixpkgs.lib.nixosSystem` function is used to build this
# configuration, the following attribute set is its parameter.
#
# Run the following command in the flake's directory to
# deploy this configuration on any NixOS system:
# sudo nixos-rebuild switch --flake .#nixos-test
#"nix-laptop" = nixpkgs.lib.nixosSystem {
# system = "x86_64-linux";
# The Nix module system can modularize configuration,
# improving the maintainability of configuration.
#
# Each parameter in the `modules` is a Nix Module, and
# there is a partial introduction to it in the nixpkgs manual:
# <https://nixos.org/manual/nixpkgs/unstable/#module-system-introduction>
# It is said to be partial because the documentation is not
# complete, only some simple introductions.
# such is the current state of Nix documentation...
#
# A Nix Module can be an attribute set, or a function that
# returns an attribute set. By default, if a Nix Module is a
# function, this function have the following default parameters:
#
# lib: the nixpkgs function library, which provides many
# useful functions for operating Nix expressions:
# https://nixos.org/manual/nixpkgs/stable/#id-1.4
# config: all config options of the current flake, every useful
# options: all options defined in all NixOS Modules
# in the current flake
# pkgs: a collection of all packages defined in nixpkgs,
# plus a set of functions related to packaging.
# you can assume its default value is
# `nixpkgs.legacyPackages."${system}"` for now.
# can be customed by `nixpkgs.pkgs` option
# modulesPath: the default path of nixpkgs's modules folder,
# used to import some extra modules from nixpkgs.
# this parameter is rarely used,
# you can ignore it for now.
#
# The default parameters mentioned above are automatically
# generated by Nixpkgs.
# However, if you need to pass other non-default parameters
# to the submodules,
# you'll have to manually configure these parameters using
# `specialArgs`.
# you must use `specialArgs` by uncomment the following line:
#
# specialArgs = {...}; # pass custom arguments into all sub module.
# modules = [
# Import the configuration.nix here, so that the
# old configuration file can still take effect.
# Note: configuration.nix itself is also a Nix Module,
# ./configuration.nix
# nixos-hardware.nixosModules.dell-xps-15-7590-nvidia
