hardware for the project(s) that use it, right?

Yes.  I could install gitlab-runner on my rpi2, get the "token"
from gitlab, and have it sit there waiting to build. In that case,
however, I'd essentially be letting remote run arbitrary shell
commands on the machine.

Seems most people are using the docker runner with gitlab ci.
I'm not sure how that could possibly work for OSX/Windows builds, so I
use virtualbox.

As for "clean slate", I guess that means different things.  I'm currently
cloning VM snapshots with *.deb dependencies installed because it saves
time.  Gitlab CI also allows you to save the previously cloned VM and use
it for subsequent builds.  But I don't trust gitlab, virtual, or gnu make to get
any of that right.
