由于与外围设备进行交互所需要的模块可能是initrd的一部分，因此内核可以非常小，但是仍然需要支持大量可能的硬件配置。
Since the necessary modules needed to interface with peripherals can be part of the initrd, the kernel can be very small, but still support a large number of possible hardware configurations.
我们不再将用户想像成代码模块，或者驱动计算机的外围设备，而想像成一个探索者在探索未知的世界。
We cease to imagine the user as a module of code or a peripheral that drives the computer, and we begin to imagine him as an explorer, probing the unknown.
