^This is what I had in mind

We'll have to duplicate it for FreeBSD anyway, so I don't understand why should
do it differently for other VM distros.

What I meant is that I don't see much value to run the builds in VMs since we
have a bunch of images ready where we can already execute the builds so it's
basically only about having resources to spawn the containers and that's where
OpenShift comes in.
I understand you reminding me that private runners cannot be used to run on
merge requests (and forks for obvious reasons), but the same applies to VMs
we're discussing in this thread. So, I wouldn't focus primarily on running the
builds there is what I'm saying.
