Estou tentando criar uma unidade de usuário systemd e iniciar quando o sistema inicializar. O serviço inicia manualmente, no entanto, não inicia na inicialização.
Ao pesquisar na Internet, aprendi que, para que as unidades de usuário iniciem na inicialização, eu supostamente preciso executar loginctl enable-linger <username>
, mas isso parece não ter tido nenhum efeito. De fato, a página de manual diz:
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.
Apesar de executar este comando, meu serviço não inicia na inicialização.
loginctl enable-linger error
A unidade:
$ cat ~/.config/systemd/user/thin\@.service
[Unit]
Description=A fast and very simple Ruby web server
[Service]
Type=simple
EnvironmentFile=/home/error/.config/thin/%i

[Install]

Quando eu reinicio, ele não está em execução:

Eu posso iniciá-lo manualmente e funciona:
$ systemctl --user start thin@redmine
$ systemctl --user status thin@redmine -l

Como faço para descobrir por que esse serviço não inicia na inicialização e como fazê-lo?
O sistema operacional é o Fedora 23 x86_64, systemd 222-10.
