- Simplify kernel/detect.h logic; introduce detectKernelVersion() - Use the detected kernel version during early startup as a first approximation of the current HOS version (which only goes up to 6.0.0) - Use set:sys (if available) during __appInit in order to refine it to the actual current HOS version
