Issue description

PR #6253 proposed a standardized format for Wayland-specific graphical systemd services, controlled by an option wayland.systemd.target.

It seems that services.wlsunset was missed, and it still uses a hard-coded value for After= and PartOf=, along with its own configuration option for WantedBy=. This should be fixed to adhere to the format and the option introduced in #6253, with the existing option defaulting to the value of wayland.systemd.target.

Of note: Another recent PR #5785 identifed and fixed a large number of services that incorrectly used graphical-session-pre.target, including wlsunset. It's possible that that PR includes additional Wayland services that were overlooked, so it's worth a look.

A very non-exhaustive search (literally just for systemdTarget and systemd.target) found me two more Wayland-only services that use their own option, that should default to use the new wayland.systemd.target one:

• services.cliphist
• services.swayr
