摘要
通过对Linux系统中的虚拟文件系统机制的深入分析,采用内核模块与用户服务程序相结合的思想,设计和实现了一种基于嵌入式Linux的分层文件系统。在该文件系统的支持下,既方便对系统软件进行升级,又保护了重要系统文件的只读性,其应用价值显著。
Based on the deep analysis of the VFS mechanism,a hierarchical file system based on embedded Linux is designed and implemented by combining the kernel module and user service application.It provides both the convenient update of the system and the better protection of the read-only system files,which is obviously of great value in commercial purposes.
