摘要
在嵌入式Linux中,根文件系统至关重要,它是所有文件和设备节点的起始点,是决定系统能否正常启动的关键。本文从一般Linux根文件系统出发,详细分析了根文件系统的构成,结合嵌入式系统的特点,提出如何利用Busybox工具建立根文件系统原型,并在此基础上添加必要的文件以实现一个简单的根文件系统,以及如何编写系统启动脚本和配置脚本来引导系统正常启动。最后在实际的ARM开发平台上验证了新生成的根文件系统。
In the embedded Linux system, the root file system is so important that it is the beginning point of all files and device modules, and it determines whether system can boot up successfully or not. In this paper, the architecture of the root file system on embedded Linux system, how to implement a root file system with the Busybox tool, and how to compose the system booting scripts are discussed. Finally, the new root file system is realized in an arm developing board, and it is verified.
