OK, first things first. For an 'experiment' with FreeBSD I first needed it installed somewhere... for the purpose of my own mental and psychical health, I choose to get FreeBSD running in a virtual machine first.
Since I'm not eager to see it (...yet) as a viable fully fledged desktop system, I was not interested in the X part of this install so I chose a minimal install, by using the "boot only" CD.
