# NixOS module {#sec-install-nixos-module}
|
|
|
|
Home Manager provides a NixOS module that allows you to prepare user
|
|
environments directly from the system configuration file, which often is
|
|
more convenient than using the `home-manager` tool. It also opens up
|
|
additional possibilities, for example, to automatically configure user
|
|
environments in NixOS declarative containers or on systems deployed
|
|
through NixOps.
|
|
|
|
To make the NixOS module available for use you must `import` it into
|
|
your system configuration. This is most conveniently done by adding a
|
|
Home Manager channel to the root user. For example, if you are following
|
|
Nixpkgs master or an unstable channel, you can run
|
|
|
|
``` shell
|
|
$ sudo nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
|
|
$ sudo nix-channel --update
|
|
```
|
|
|
|
and if you follow a Nixpkgs version 24.05 channel, you can run
|
|
|
|
``` shell
|
|
$ sudo nix-channel --add https://github.com/nix-community/home-manager/archive/release-24.05.tar.gz home-manager
|
|
$ sudo nix-channel --update
|
|
```
|
|
|
|
It is then possible to add
|
|
|
|
``` nix
|
|
imports = [ <home-manager/nixos> ];
|
|
```
|
|
|
|
to your system `configuration.nix` file, which will introduce a new
|
|
NixOS option called `home-manager.users` whose type is an attribute set
|
|
that maps user names to Home Manager configurations.
|
|
|
|
For example, a NixOS configuration may include the lines
|
|
|
|
``` nix
|
|
users.users.eve.isNormalUser = true;
|
|
home-manager.users.eve = { pkgs, ... }: {
|
|
home.packages = [ pkgs.atool pkgs.httpie ];
|
|
programs.bash.enable = true;
|
|
|
|
# The state version is required and should stay at the version you
|
|
# originally installed.
|
|
home.stateVersion = "24.05";
|
|
};
|
|
```
|
|
|
|
and after a `sudo nixos-rebuild switch` the user eve's environment
|
|
should include a basic Bash configuration and the packages atool and
|
|
httpie.
|
|
|
|
:::{.note}
|
|
If `nixos-rebuild switch` does not result in the environment you expect,
|
|
you can take a look at the output of the Home Manager activation script
|
|
output using
|
|
|
|
``` shell
|
|
$ systemctl status "home-manager-$USER.service"
|
|
```
|
|
:::
|
|
|
|
If you do not plan on having Home Manager manage your shell
|
|
configuration then you must add either
|
|
|
|
``` bash
|
|
. "$HOME/.nix-profile/etc/profile.d/hm-session-vars.sh"
|
|
```
|
|
|
|
or
|
|
|
|
``` bash
|
|
. "/etc/profiles/per-user/$USER/etc/profile.d/hm-session-vars.sh"
|
|
```
|
|
|
|
to your shell configuration, depending on whether
|
|
[home-manager.useUserPackages](#nixos-opt-home-manager.useUserPackages) is enabled. This file can
|
|
be sourced directly by POSIX.2-like shells such as
|
|
[Bash](https://www.gnu.org/software/bash/) or [Z
|
|
shell](http://zsh.sourceforge.net/). [Fish](https://fishshell.com) users
|
|
can use utilities such as
|
|
[foreign-env](https://github.com/oh-my-fish/plugin-foreign-env) or
|
|
[babelfish](https://github.com/bouk/babelfish).
|
|
|
|
:::{.note}
|
|
By default packages will be installed to `$HOME/.nix-profile` but they
|
|
can be installed to `/etc/profiles` if
|
|
|
|
``` nix
|
|
home-manager.useUserPackages = true;
|
|
```
|
|
|
|
is added to the system configuration. This is necessary if, for example,
|
|
you wish to use `nixos-rebuild build-vm`. This option may become the
|
|
default value in the future.
|
|
:::
|
|
|
|
:::{.note}
|
|
By default, Home Manager uses a private `pkgs` instance that is
|
|
configured via the `home-manager.users.<name>.nixpkgs` options. To
|
|
instead use the global `pkgs` that is configured via the system level
|
|
`nixpkgs` options, set
|
|
|
|
``` nix
|
|
home-manager.useGlobalPkgs = true;
|
|
```
|
|
|
|
This saves an extra Nixpkgs evaluation, adds consistency, and removes
|
|
the dependency on `NIX_PATH`, which is otherwise used for importing
|
|
Nixpkgs.
|
|
:::
|
|
|
|
:::{.note}
|
|
Home Manager will pass `osConfig` as a module argument to any modules
|
|
you create. This contains the system's NixOS configuration.
|
|
|
|
``` nix
|
|
{ lib, pkgs, osConfig, ... }:
|
|
```

Once installed you can see [Using Home Manager](#ch-usage) for a more detailed
|
|
description of Home Manager and how to use it.
