Why not create a system user that has access to input and run the service with that user?
I personally have this in my configuration to use ydotool with libinput-gestures:
let
configFile = ...;
in
{
# https://github.com/NixOS/nixpkgs/issues/70471
# Chown&chmod /dev/uinput to owner:root group:input mode:0660
boot.kernelModules = [ "uinput" ];
services.udev.extraRules = ''
SUBSYSTEM=="misc", KERNEL=="uinput", TAG+="uaccess", OPTIONS+="static_node=uinput", GROUP="input", MODE="0660"
'';
users.users.libinput-gestures = {
group = "input";
description = "libinput gestures/gebaard user";
isSystemUser = true;
inherit (config.users.users.nobody) home;
};
systemd.services.libinput-gestures = {
description = "Touchpad gesture listener";
reloadIfChanged = true;
partOf = [ "graphical.target" ];
requires = [ "graphical.target" ];
after = [ "graphical.target" ];
wantedBy = [ "graphical.target" ];
serviceConfig = {
Type = "simple";
ExecStart = "${pkgs.libinput-gestures}/bin/libinput-gestures -c ${configFile}";
#ExecStart = "${pkgs.gebaar-libinput}/bin/gebaard";
#Environment = [ ''"XDG_CONFIG_HOME=${configFile}"'' ];
User = config.users.users.libinput-gestures.name;
Group = config.users.users.libinput-gestures.group;
};
};

This still needs a daemon. |

services are almost always put under multi-user.target.

The tool re-execs itself, right?

Isn't systemPackages available in the systemd unit?

No. Our systemd units specify PATH.

Motivation for this change
ydotool requires a daemon to be started for it to be used:
