Estou tentando criar uma unidade de usuário systemd e iniciá-lo quando o sistema for inicializado. O serviço é iniciado manualmente, mas não é iniciado na inicialização.
Pesquisando na Internet, aprendi que, para que as unidades do usuário iniciem na inicialização, eu supostamente preciso executar loginctl enable-linger <username>
, mas isso parece não ter tido nenhum efeito. De fato, a página man 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

Quando reinicializo, não está em execução:

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

Como descubro por que este serviço não inicia na inicialização e o faz assim?
O sistema operacional é o Fedora 23 x86_64, systemd 222-10.
