Re: Debian 8 how to install and run init.d scripts?

5.) 
Instead of init.d scripts create systemd units.

https://freedesktop.org/wiki/Software/systemd/

About your gitlab-runner.service failure:

https://wiki.debian.org/systemd#Failed_units
HINT: Extensive debugging information about systemd is on this
FreeDesktop page. https://freedesktop.org/wiki/Software/systemd/Debugging/

What is in gitlab-runner.service on that one server anyways?

Somewhen in 2016-2018 someone on debian planet posted multiple blogs of
a great systemd introduction series, I can't find my bookmark right now
:(
