nix-darwin: simplify activation script invocation 
In #587, kalbasit introduce the `-i` flag so the sudo invocation would
run in an environment with `HOME` set to the correct value for the
target user. This was necessary to be able to set up multiple users
without interfering with the invoking user's `HOME`.

In #807, I switched to `-s` instead because I managed to get an
invalid shell set for my user by switching `useUserPackages` from
`true` to `false` which changes the location where packages are
installed and `~/.nix-profile/bin/<my-shell>` was no longer valid.
This was based on the assumption that `SHELL` would be set to some
sensible value by Home Manager at this point. This turned out to be
false as reported in #2900.

In 0ced6d6d (this commit's parent at this time), I explicitly set
`SHELL` to `${pkgs.bash}` so it is definitely set to a good shell when
invoking the activation script.

However, #807 broke activation for multiple users, the original
motivation for `-i`, as reported in #2856. I fixed this in #2857 by
additionally passing `--set-home`.

Further discussion with rycee in #3040 made me realize that the
activation script already has a good Nix store bash shebang. So all
the problems have been caused, not by the shell used for the
activation script but by sudo trying to use a different shell at all.
`-i` uses the shell set in the `passwd` file for the target user, but
this can become invalid as happened to me. `-s` uses either `SHELL` if
it's defined or the invoking user's shell as set in the `passwd` file.
By explicitly setting this to a shell provided by Nix we make sure
we're not trying to launch a non-existent shell. However, we're
clearly already running in an existing shell and because of
`--set-home` we can activate other users properly so there's not
actually any need to try to have sudo start a different shell first,
it just adds an extra process that then goes on to run the activation
script with a good bash because of the shebang.

Dropping `-s` altogether and keeping `--set-home` should avoid all of
these issues.

Home Manager using Nix

This project provides a basic system for managing a user environment using the Nix package manager together with the Nix libraries found in Nixpkgs. It allows declarative configuration of user specific (non global) packages and dotfiles.

Usage

Before attempting to use Home Manager please read the warning below.

For a systematic overview of Home Manager and its available options, please see

If you would like to contribute to Home Manager then please have a look at the contributing chapter of the manual.

Words of warning

Unfortunately, it is quite possible to get difficult to understand errors when working with Home Manager, such as infinite loops with no clear source reference. You should therefore be comfortable using the Nix language and the various tools in the Nix ecosystem. Reading through the Nix Pills document is a good way to familiarize yourself with them.

If you are not very familiar with Nix but still want to use Home Manager then you are strongly encouraged to start with a small and very simple configuration and gradually make it more elaborate as you learn.

In some cases Home Manager cannot detect whether it will overwrite a previous manual configuration. For example, the Gnome Terminal module will write to your dconf store and cannot tell whether a configuration that it is about to be overwritten was from a previous Home Manager generation or from manual configuration.

Home Manager targets NixOS unstable and NixOS version 22.05 (the current stable version), it may or may not work on other Linux distributions and NixOS versions.

Also, the home-manager tool does not explicitly support rollbacks at the moment so if your home directory gets messed up you'll have to fix it yourself. See the rollbacks section for instructions on how to manually perform a rollback.

Now when your expectations have been built up and you are eager to try all this out you can go ahead and read the rest of this text.

Contact

You can chat with us on IRC in the channel #home-manager on OFTC. There is also a Matrix room, which is bridged to the IRC channel.

Installation

Home Manager can be used in three primary ways:

  1. Using the standalone home-manager tool. For platforms other than NixOS and Darwin, this is the only available choice. It is also recommended for people on NixOS or Darwin that want to manage their home directory independently of the system as a whole. See Standalone installation in the manual for instructions on how to perform this installation.

  2. As a module within a NixOS system configuration. This allows the user profiles to be built together with the system when running nixos-rebuild. See NixOS module installation in the manual for a description of this setup.

  3. As a module within a nix-darwin system configuration. This allows the user profiles to be built together with the system when running darwin-rebuild. See nix-darwin module installation in the manual for a description of this setup.

Home Manager provides both the channel-based setup and the flake-based one. See Nix Flakes for a description of the flake-based setup.

Translations

Home Manager has basic support for internationalization through gettext. The translations are hosted by Weblate. If you would like to contribute to the translation effort then start by going to the Home Manager Weblate project.

Translation status

Releases

Home Manager is developed against nixpkgs-unstable branch, which often causes it to contain tweaks for changes/packages not yet released in stable NixOS. To avoid breaking users' configurations, Home Manager is released in branches corresponding to NixOS releases (e.g. release-22.05). These branches get fixes, but usually not new modules. If you need a module to be backported, then feel free to open an issue.
