I'm not sure I consider configuring firewall rules at startup using an init script "really really shady". Turns out (quite unsurprisingly) that you can't run multiple instances of the iptables command simultaneously. I don't really want to get into the whole debate about whether parallelizing startup scripts is better or not. I'm not saying it's not, but that's beside the point. The point was that parallelizing startup scripts leads to a set of problems that didn't exist before. It's annoying to see people argue that those problems don't exist. It's like arguing that the problem of flat tyres aren't more common for people driving cars than they are for people riding horses. It's utter nonsense, no matter how many other advantages cars may have.
