Pourquoi mon unité utilisateur systemd ne démarre-t-elle pas au démarrage?

J'essaie de créer une unité utilisateur systemd et de la faire démarrer au démarrage du système. Le service démarre manuellement, mais il ne démarre pas au démarrage.

En recherchant sur Internet, j'ai appris que pour que les unités utilisateur démarrent au démarrage, je devrais supposément exécuter loginctl enable-linger <username>, mais cela semble n'avoir eu aucun effet. En effet, la page de manuel dit:

       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.

Malgré l'exécution de cette commande, mon service ne démarre pas au démarrage.

loginctl enable-linger error

L'unité:

$ cat ~/.config/systemd/user/thin\@.service

Lorsque je redémarre, il ne fonctionne pas:

Comment puis-je comprendre pourquoi ce service ne démarre pas au démarrage et le faire faire?

Le système d'exploitation est Fedora 23 x86_64, systemd 222-10.

Des chiffres que j'aurais compris par moi-même.

L'indice était ici, dans la sortie du service utilisateur:

Dec 23 19:43:27 redmine systemd[613]: Reached target Default.

Mon unité demandait à être chargée de multi-user.target, mais il n'y a pas une telle cible dans l'utilisateur systemd.

J'ai changé cela en default.target dans le fichier d'unité, a désactivé et réactivé le service, et il démarre maintenant au démarrage.

[Install]
WantedBy=default.target

et alors

$ systemctl --user disable thin@redmine
Removed symlink /home/error/.config/systemd/user/multi-user.target.wants/[email protected].
$ systemctl --user daemon-reload
$ systemctl --user enable thin@redmine
Created symlink from /home/error/.config/systemd/user/default.target.wants/[email protected] to /home/error/.config/systemd/user/[email protected].
