After update to sd-switch 0.5.0, `home-manager switch` failed with the
following error message:
> Error: Error switching
>
> Caused by:
> 0: Failed to build switch plan
> 1: No such file or directory (os error 2)
This was caused by a non-existing target unit directory due to no user
services being managed by home-manager. This change makes sd-switch
run with pkgs.emptyDirectory as the target in such cases.
Closes: https://github.com/nix-community/home-manager/issues/5552
Due to the defaults in `systemd.user.settings`, the default value when
there are no settings explicitly set is `{ Manager = { }; }`. This
means an empty file is created even when `systemd.user.settings` is
never used in home-manager configuration. Since user’s `user.conf` is
preferred to the global `/etc/systemd/user.conf`, this can cause any
values set in the latter to be discarded.
The `systemd.user.extraConfig` provides a way to generate a
`systemd-user.conf(5)` file for the user.
This is the home-manager equivalent of NixOS’s option of the same
name, with the difference that NixOS’s option generates a `user.conf`
file that is shared between all users.
These (and the `*MD` functions apart from `literalMD`) are now no-ops
in nixpkgs and serve no purpose other than to add additional noise and
potentially mislead people into thinking unmarked DocBook documentation
will still be accepted.
Note that if backporting changes including documentation to 23.05,
the `mdDoc` calls will need to be re-added.

This process was automated by [my fork of `nix-doc-munge`]. All
conversions were automatically checked to produce the same DocBook
result when converted back, modulo minor typographical/formatting
differences on the acceptable-to-desirable spectrum.

`nix-doc-munge` can't handle these, which is understandable as I can
barely handle them either. There are a few infelicities here: the
current processor can't handle multiple terms to one description in
a description list so they get comma-separated in one case, and one
case that should ideally render as a `<figure>` with a `<figcaption>`
in HTML is reduced to a paragraph with some `<strong>` text. (Which, in
fairness, is how it rendered in practice with the DocBook anyway.) The
docs generator has since been updated to handle figures, but we can't
use it until moving off DocBook output.
Allow modules to define systemd services on macOS. It won't actually
have any effect, but it would allow modules to define both systemd
services and launchd agents without boilerplate conditionals.
As a consequence of this change, each module would have to check for
compatibility with the OS target instead.
Units with
Install.RequiredBy = [ target ]
set will now be linked in the
${target}.requires
directory. Similar to how `Install.WantedBy` already causes a link in
the
${target}.wants
directory.

There is a need to manage XDG Base Directory system directory
environment variables in Home Manager modules. There is an existing
mechanism in `targets.genericLinux.extraXdgDataDirs', but this does not
apply to NixOS systems.
Furthermore, it is important that `XDG_CONFIG_DIRS' and `XDG_DATA_DIRS'
are set in both login shells (to support getty and SSH sessions) as well
as the systemd user manager (to propagate them to user services and
desktop environments).
The first need is addressed by adding the `xdg.systemDirs' module, which
configures lists of directory names for both `config' and `data'
directories. These are then set in
`$XDG_CONFIG_DIR/environment.d/10-home-manager.conf' and picked up by
the systemd user manager.
To make these, and other variables set in
`systemd.user.sessionVariables', available in login shells, an
additional step is added to `etc/profile.d/hm-session-vars.sh' which
exports the result of
`user-environment-generators/30-systemd-environment-d-generator' which
is shipped with systemd. The effect of this generator is to print
variables set on the systemd user manager such that shells can import
these into their environment.
This causes list values to be emitted as a list of key-value pairs
instead of a single key-value pair where the value is space separated.
This is useful, e.g., for socket units that would like to specify more
than one `ListenStream=` address.
This makes the systemd module use the sd-switch application to perform
the unit switch during a generation activation.
Since the closure of sd-switch is relatively lightweight we
unconditionally pull it in as a dependency. We simultaneously remove
the `systemd.user.startServices` option and perform the switch action
automatically.

Otherwise, the pager (typically `less`) pauses execution of
`home-manager switch` until the pager is dismissed, if the content is
larger than would fit on the screen.
PR #1175
This change makes use of the `extend` function inside `lib` to inject
a new `hm` field containing the Home Manager library functions. This
simplifies use of the Home Manager library in the modules and reduces
the risk of accidental infinite recursion.
PR #994
This should allow more sensible merging behavior. In particular, with
this change it is possible to use, for example, `mkForce` for greater
control of merging.
Fixes#543
The current documentation does not provide guidance to users on how
systemd units are defined in Home Manager. A user may expect the
configuration to be similar to NixOS, when it actually differs.
Fixes#418
This removes the need for monolithic unit definitions and allows
users to modify existing units.
Example:
```
{
systemd.user.services.owncloud-client.Unit.OnFailure = "my-notify-service";
}
```
Curiously the `who` command sometimes does not list logged-in users,
resulting in systemd not being reloaded. Instead we use
systemctl --user is-system-running
to more directly detect whether systemd is running.
This is a NixOS module that is intended to be imported into a NixOS
system configuration. It allows the system users to be set up directly
from the system configuration.
The actual profile switch is performed by a oneshot systemd unit per
configured user that acts much like the regular `home-manager switch`
command.
With this implementation, the NixOS module does not work properly with
the `nixos-rebuild build-vm` command. This can be solved by using the
`users.users.<name?>.packages` option to install packages but this
does not work flawlessly with certain Nixpkgs packages. In particular,
for programs using the Qt libraries.
Unfortunately systemd derives nonsensical unit names when the unit
file is a link to a link to a file. This commit ensures that any file
whose target path matches the pattern `*/systemd/user/*` will be
reachable with only one link hop.
This also reverts f52ec0df7c, which
contained a temporary fix. This commit is an improvements in that it
is more explicit and also handles unit files given directly as a home
file source.
