systemdユーザーユニットを作成し、システムの起動時に開始するようにしています。サービスは手動で開始されますが、起動時に開始されません。
インターネットの検索から、ユーザーユニットが起動時に起動するためにはloginctl enable-linger <username>
、おそらく実行する必要があることを学びましたが、これはまったく効果がなかったようです。実際、manページには次のように書かれています。
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.
このコマンドを実行しても、ブート時にサービスが開始されません。
loginctl enable-linger error

私はそれを手動で起動することができ、それは動作します:
$ systemctl --user start thin@redmine
$ systemctl --user status thin@redmine -l

このサービスが起動時に開始しない理由を把握し、開始する方法を教えてください。
