This commit deprecates profile management from the activation script. The profile management is instead the responsibility of the driving software, for example, the `home-manager` tool in the case of standalone installs. The legacy behavior is still available for backwards compatibility but may be removed in the future. The new behavior resolves (or moves us closer to resolving) a number of long standing open issues: - `home-manager switch --rollback`, which performs a rollback to the previous Home Manager generation before activating. While it was previously possible to accomplish this by activating an old generation, it did always create a new profile generation. This option has been implemented as part of this commit. - `home-manager switch --test`, which activates the configuration but does not create a new profile generation. This option has _not_ been implemented here since it relies on the current configuration being activated on login, which we do not currently do. - When using the "Home Manager as a NixOS module" installation method we previously created an odd `home-manager` per-user "shadow profile" for the user. This is no longer necessary. This has been implemented as part of this commit. Fixes #3450

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](#words-of-warning).
|
|
|
|
For a systematic overview of Home Manager and its available options, please see:
|
|

|
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-24.05`). These branches get
|
|
fixes, but usually not new modules. If you need a module to be backported, then
|
|
feel free to open an issue.
|
|
|
|
Words of warning
|
|
----------------
|
|
|
|
Unfortunately, it is quite possible to get difficult to understand errors when
|
|
working with Home Manager. You should therefore be comfortable using the [Nix][]
|
|
language and the various tools in the Nix ecosystem.
|
|
|
|
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 24.05 (the current
|
|
stable version), it may or may not work on other Linux distributions and NixOS
|
|
versions.
|
|
|
|
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.

You can chat with us on IRC in the channel [#home-manager][] on [OFTC][]. There
|

is also a [Matrix room](https://matrix.to/#/#hm:rycee.net), which is bridged to

|
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][manual standalone install] for instructions on how to perform this
|
|
installation.
|
|
|
|
1. 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" in the manual][manual nixos install] for a description of
|
|
this setup.
|
|
|
|
1. 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" in the manual][manual nix-darwin install] for a
|
|
description of this setup.
|
|
|
|
Home Manager provides both the channel-based setup and the flake-based one. See
|
|
[Nix Flakes][manual nix flakes] for a description of the flake-based setup.
|
|
|
|
Translations
|
|
------------
|
|
|
|
Home Manager has basic support for internationalization through
|
|
[gettext](https://www.gnu.org/software/gettext/). The translations are hosted by
|
|
[Weblate](https://weblate.org/). If you would like to contribute to the
|
|
translation effort then start by going to the [Home Manager Weblate
|
|
project](https://hosted.weblate.org/engage/home-manager/).
