Service Unit Missing Parameters

[natriumpt]

Formula Name

sunshine-beta

Homebrew Version

Homebrew 5.1.7

Operating System

Bazzite 43.20260420

Describe the Issue

The installation works correctly, but the created service unit is missing parameters.

The service unit created by Homebrew doesn't match the one that exists in dev.lizardbyte.app.Sunshine.service.in on the main repository.

When setting up the service using brew services start sunshine-beta it enables a service unit that is missing the After=graphical-session.target xdg-desktop-autostart.target xdg-desktop-portal.service line, resulting in Sunshine attempting to initialize before Wayland is ready.

Depending on your setup, this may lead to errors due to WAYLAND_DISPLAY not being set.

It works correctly after restarting, and it works as expected on boot after overriding the service unit file.
