初始ram磁盘最初是设计用来通过一个临时根文件系统来作为内核到最终的根文件系统之间的桥梁。
The initial RAM disk was originally created to support bridging the kernel to the ultimate root file system through a transient root file system.
应该将这当作一根临时需要的拐杖，但最后一定可以摆脱它。
You should treat this as a crutch - necessary, but something you want to do without in the long run.
因为根用户可以更改系统上的任何文件，它可以在临时构建R PM期间随意添加外部文件或删除重要文件，从而更改正在运行的系统。
Because root can alter any file on the system, it was easy to inadvertently alter a running system by adding extraneous files or removing important files during interim builds of an RPM.
