After kernel mount the real device to "/" , is the initramfs still usefull ? If so ,it is mounted at which entry? At the end stage of boot , kernel will execute a init file , whether this file locates at initramfs address space *or* the device mounted at "/" ? I feel confused of this point . -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
