The kernel then mounts this initrd as part of the two-stage boot process to load the modules to make the real file systems available and get at the real root file system.

内核然后会将这个 initrd 文件作为其两阶段引导过程的一部分来加载模块，这样才能稍后使用真正的文件系统，并挂载实际的根文件系统。

In a nutshell, the kernel is booted as normal; but instead of mounting the "real" root file system, a miniature root filesystem is created in RAM, and that is mounted.

简而言之，内核像平常一样引导；但不安装“真实的”根文件系统，而是在RAM中创建微型根文件系统并安装该系统。

Numerous tools, such as mkinitrd, can be used to automatically build an initrd with the necessary libraries and modules for bridging to the real root file system.

有很多工具，例如mkinitrd，都可以用来使用必要的库和模块自动构建initrd，从而用作与真实的根文件系统之间的桥梁。
