Another example: console / keyboard config. In OpenBSD, I set this up through wscons. If set here, my keyboard settings get propagated in a robust, non duplicative way to X11. Contrast this with Linux, where you need to set up your keyboard config in at least two places to have, say, Dvorak in X11 and the console.
It's a minor thing, and one that Linux distros "solve" during installation by setting up the relevant configs. But it's more elegant in OpenBSD. Maybe that's because OpenBSD writes documentation that answers questions like, "How do a change my keyboard layout?" In OpenBSD, it's a simple answer. If the situation were the same as Linux, the answer would be longer. Maybe seeing that inessential redundancy in print is what spurs the project to action.
