Not really. At least not in the way that blog post has been presented. Normally you’ll be told as you install things if there is any manual amendments to configure files required. So it’s all quite discoverable. That said, if you’re used to Linux and Windows where you can just start services then daemons on FreeBSD might catch you out because you need to (or rather, get “told” to) manually edit the rc.conf file for any services you want. It only takes a few seconds to do but I can see why some people might find it an annoyance if they’re not used to manually editing system files (personally I don’t mind but I’ve been using UNIX for decades).
