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.

Using the option
wayland.windowManager.hyprland.systemd.enableXdgAutostart
users can now choose to start applications present in
`$XDG_CONFIG_HOME/autostart` when starting their sway session.

We currently have no way of specifying the sender's name inside the
From field, making a patch sent through `git send-email` appear as
coming from "xxx@domain.com".
In this commit we make this field follow the standard
realName <email>
format.
In the generated neomutt configuration, source the optional
`vim-keys.rc` before applying the `binds` configuration, to allow the
user to override keybindings from `vim-keys.rc`.
Adapt the test files to account for the empty space left by the unset
`vimKeys` option.
This enables a module system feature documented here:
https://nixos.org/manual/nixpkgs/stable/index.html#module-system-lib-evalModules-param-class
For example, it allows a mistake to be caught, which is loading a
NixOS module into home-manager. This only works when the offending
module declares what it's for with a `_class` attribute.
It is not expected that users declare the `_type`, because the payoff
is small. It is only expected to be set by generic code, such as
functions or libraries that help with the "publishing" of modules
(e.g. flake-parts, flake-utils).
The class feature has been available in the module system since
https://github.com/NixOS/nixpkgs/pull/197547, merged May 6, 2023. It
has been part of all releases since 23.05-beta. The last NixOS release
that did _not_ support it has been end-of-life for close to a year
now.
Example:
(lib.homeManagerConfiguration {
pkgs = nixpkgs.legacyPackages.x86_64-linux;
modules = [{ _class = "nixos"; imports = [ ./foo.nix ]; }];
}).activation-script
Corresponding error:
error: The module <unknown-file> was imported into homeManager instead of nixos.
(`<unknown-file>` can be improved by also setting `_file`, if known; a
much older feature)
