Not to nitpick, but the title should have AS capitalized. It’s confusing with the current capitalization.
I think HN tends to undo all caps words unless it's an acronym HN specifically recognizes. Guessing BGP, GRE, and FreeBSD are understood but AS is not.
Right! I was confused for a bit until I started reading it.
Otherwise, getting to know the power of FreeBSD is awesome. Thanks for creating the blog!
