Building Ports on a "Production" System

I am limited to one OpenBSD/amd64 box in my environment. And, unfortunately, it is my "production" server (at home).

So that I could build and test ports on my "production" server without installing millions of dependencies and polluting my environment, I set up a SSH-based chroot environment to build the ports.

2nd Install, 1 Disk

Here is the problem I'm trying to solve: I have an Intel Mac Mini that I'd like to dual boot multiple versions of OpenBSD. I need to be able to boot into another instance of OpenBSD remotely and without a serial port, I had to come up with a way to choose which OS I want to boot to.

I installed OpenBSD 4.4-current normally on wd0a (wd0b = swap, wd0d = /tmp, wd0e = /var, wd0f = /usr and wd0g = /home).

Here is how I set the machine up with OpenBSD 4.3 installed on wd0h.
