Oh my fucking god this was by far the most awful and boring and tedious day in my entire life. Also, dear FreeBSD people: please don't sue me. I tried really hard to comply with all the copyright stuff, but it is absolutely possible i made a mistake. Just DM me and i'll do everything in my power to fix it, even if that means releasing entire portions of GayBSD under the BSD license. I don't care, i just want stuff to work. (i'm including this message to use it as possible evidence in case i get sued to show my good will)
