Does it work after
systemctl --user daemon-reload
?Yes, it worked after `daemon-reload`. Thank you so much!
"daemon-reload" reloads all unit files in the system. It seems to me such a big remedy for starting a single service. Is this the expected workflow or a workaround?
Also I tried to add a 2nd service "foo2.service" in the same way, now I don't have to run "daemon-reload" and it can start. I'm wondering why.
Thanks

User instance does not have this target.
