Any setting a user must adjust or manage to make things work is a bug. Everything must work instantly and reliably in any minimally functional environment, and installation must be single-step. This has its own problems, as you risk building hidden dynamic behaviour that can behave unpredictably. The notion of "everything must work instantly" also suggests enabling all possible services immediately, which is widely known as a terrible idea security-wise (although it may well be usable).
