ฉันพยายามสร้างหน่วยผู้ใช้ systemd และเริ่มต้นเมื่อระบบบูท บริการเริ่มต้นด้วยตนเอง แต่ไม่เริ่มทำงานเมื่อเริ่มระบบ
จากการค้นหาอินเทอร์เน็ตฉันได้เรียนรู้ว่าเพื่อให้หน่วยผู้ใช้เริ่มการบูทฉันควรจะเรียกใช้loginctl enable-linger <username>
แต่สิ่งนี้ดูเหมือนว่าจะไม่มีผลเลย แท้จริงหน้าคนพูดว่า:
Enable/disable user lingering for one or more users. If enabled for a specific user, a user manager is spawned for the user at boot and kept around after logouts. This allows users who are not logged in to run long-running services.
แม้จะใช้คำสั่งนี้ แต่บริการของฉันก็ยังไม่เริ่มการบู๊ต
loginctl enable-linger error

ฉันจะทราบได้อย่างไรว่าเหตุใดบริการนี้จึงไม่เริ่มทำงานเมื่อเริ่มระบบและให้ทำเช่นนั้น
