About a year ago the Armbian build framework made its transition to the next generation. Tons of code have been rewritten, new features added, existing one were rewritten in Python from scratch. The main driving force behind it was Ricardo Pardini. With this transition some build options regular users were quite familiar, KERNEL_CONFIGURE or CREATE_PATCHES for example, were deprecated and this lead to confusion and incomprehension, last but not least due to the more or less constant lack of detailed framework documentation. So users had to conjecture how things work from reading the code, forums and answers to issue reports. This situation even forced the Armbian developers to bring back the old switches to some extend. In today’s topic I want to break down kernel-config as the now modern way to configure your Linux kernel configuration before building.
