Modify source on Omnibus install?

I want to disable email confirmation for new users, and rather than wait for the team to do it, I thought I’d try to tackle it myself.

I have a functional GitLab instance built from the Omnibus package, so rather than build a new server from source, can I modify the code and somehow recompile things in place?

That sounds like a security nightmare if all new users are automatically valid.

Just review them manually and don’t change anything.

On a public system, of course. We’re not on the internet, though, and every user on the network has already been authorized through other means. It’s a risk management consideration - if there’s no risk, why bother with the mitigation?
