Próbuję utworzyć systemową jednostkę użytkownika i uruchomić ją podczas uruchamiania systemu. Usługa uruchamia się ręcznie, jednak nie uruchamia się przy rozruchu.
Po przeszukaniu Internetu dowiedziałem się, że aby jednostki użytkownika mogły rozpocząć się przy starcie systemu, podobno muszę uruchomić loginctl enable-linger <username>
, ale wydaje się, że nie miało to żadnego wpływu. Rzeczywiście strona man mówi:
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.
Pomimo uruchomienia tego polecenia moja usługa nie uruchamia się przy rozruchu.
loginctl enable-linger error
Jednostka:
$ cat ~/.config/systemd/user/thin\@.service

Mogę uruchomić go ręcznie i działa:
$ systemctl --user start thin@redmine
$ systemctl --user status thin@redmine -l

Jak dowiedzieć się, dlaczego ta usługa nie uruchamia się przy rozruchu, i przekonać się do tego?
System operacyjny to Fedora 23 x86_64, systemd 222-10.
