I’m writing a step by step setup for a self hosted gitea instance (on CentOS 7) and hit the stupidest bug (if you can call it that) of systemd. After writing the gitea service file I was getting the following error:
[root@gitea ~]# systemctl start giteaselfhost Failed to start giteaselfhost.service: Unit not found.
After a few hours of maddening permission checks and debugging, the problem was that I had a
Requires dependency to a service file that wasn’t there.
Removing the broken dependency made the service work, so hopefully at some point systemd will give nicer errors when missing dependencies.
