GitLab: How to disable automatic startup?

Question

I have not found a way to disable the automatic startup and it ends up using too much RAM when I'm not using.

The init files are not inside /etc/init or init.d.

I try update-rc.d gitlab remove and no results.

I am using GitLab 8.5.4 in Debian 8.

Problem is solved!

I contacted the GitLab by their official page on Facebook and here is the answer.

I am using GitLab in a Desktop and it was using ~700MB. If you too want turn off GitLab on startup, just execute in a terminal:

sudo systemctl disable gitlab-runsvdir.service
