homeConfigurations

man home-managerに書いてる予約されたattr名

--flake flake-uri［#name］

Build Home Manager configuration from the flake, which must contain the output homeConfigurations.name.

If no name is specified it will first try username@hostname and then username.

こんな感じで定義したとき

code:flake.nix

{

description = "my dotfiles";

inputs = {

nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";

home-manager = {

url = "github:nix-community/home-manager/release-24.11";

inputs.nixpkgs.follows = "nixpkgs";

};

};

outputs = { nixpkgs, home-manager, ...}: {

homeConfigurations = {

mrsekut = home-manager.lib.homeManagerConfiguration {

pkgs = import nixpkgs {

system = "aarch64-darwin";

};

};

};

};

}

こんな感じで指定して呼び出す

$ home-manager switch --flake .#mrsekut

manの説明の通り、

usernameが一致していれば、雑に

$ home-manager switch --flake .

とかでも同じ挙動になる
