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.
This is done by exploiting the fact that home files will be copied if
the executable bit of the source file and the target file is
different. This should be considered a hack until some nicer solution
is found.
Note, we still pull in the user's `PATH` in case the user has defined
their own activation blocks that depend on additional tools.
Eventually this will be deprecated and removed.
See #99.
This commit causes an error to be printed if running under a non-Linux
system when a systemd service, target, or timer is active.
It will also prevent running systemd during activation if running
under a non-Linux system.
