I just did it myself and got nearly the same files like you. I added nginx.service to the wants of gitlab.service.

Furthermore I use unicorn_rails in daemon-mode (-D) and used the service type fork. What's the difference?

Thanks for providing your files! I'm working on a setup based on opensuse 12.1/12.2 64bit.

I'm not sure about daemon-mode. I think it doesn't matter when PIDFile parameter is specified.

I personally use these units on my ArchLinux/i686 and ArchLinuxArm setups.
