It is not reasonable to flash a large cluster with current methods, which involve writing a floppy disk or CD image and attending to each computer individually; an alternative is required.

用当前的方法不能合理地刷新大型集群，需要写入一张软盘或CD镜像，并需要对每台计算机分别执行刷新；所以需要另一种方法。

What this has meant is that, in order to insure against computer crashes (which are eventually inevitable), you've had to back up your files to a remote disk (another drive, a CD-ROM, etc.).

这意味着，为了避免计算机崩溃带来的损失(计算机终究是会崩溃的)，我们必须把文件备份到远程磁盘中(其他硬盘或CD - ROM等媒介)。

You can copy the /etc/hosts file that you have just created to a floppy disk or CD-ROM (if you have a writeable CD-ROM drive) and copy that file to the /etc directory of each computer in your LAN.

你可以将 /etc/hosts 文件拷贝到软盘或光盘（如果你拥有一个光盘刻录机）上，然后再从软盘或光盘上拷贝到待配置计算机的 /etc 目录下。
