I don't care about SDN per se, but I do desire a home network that I can configure and deploy (or easily re-bootstrap) from a git repo with a plain text editor.

I don't care about SDN per se, but I do desire a home network that I can configure and deploy (or easily re-bootstrap) from a git repo with a plain text editor. The result is that I use NixOS for my NAT gateway/firewall, and simply live without fancier network features (I only have two NICs in that machine). For wifi I begrudgingly use an off-the-shelf wifi router combo in bridge mode.
