Why do I just want to scream TROLL!!!!
Seriously, by all reasonable accounts the Wiki page referenced seems to be referring to any variant of *NIX, including any of the BSD variants. Are you going to write out every variant of *nix every time you reference this stuff? Your posts will end up two miles long on the first mention.
Now, if you have specific knowledge as to why this particular issue is not an issue with BSD variants, or pfSense in particular, I'd love to hear it.
