文详细分析了MINIX文件系统的磁盘布局及其在Linux OS中的实现。站在当今时代，MINIX文件系统是如此简陋，以至于在现实中几乎没有实用

价值。但它毕竟曾经是教学操作系统MINIX的主文件系统，最初的Linux也是在MINIX文件系统上开始成长的。在Linux内核源代码树中依然保留

着MINIX File System的分支，而且它依然被维护，以与Linux文件系统的架构变化同步。从实用角度说，实在没有这个必要，但Linus Torvalds

还保留着它，或许Linus有点舍不得吧？从学习文件系统角度说，MINIX文件系统是一个极好的起点，它简单，但拥有Unix文件系统的主要要素。以

它为基础，再学习Linux OS的主流文件系统，比如ext2/ext3，会轻松得多（最起码这是我的学习体会）-Wen detailed analysis of the disk layout MINIX file system and its implementation in the Linux OS. Standing in the modern era, MINIX file system is so simple, that in reality almost no practical value. But it is, after all, was the main teaching MINIX operating system, file system, Linux is the first on the MINIX file system begins to grow. Still retains the MINIX File System branch in the Linux kernel source tree, and it is still being maintained to structural change and Linux file system synchronization. From a practical point of view, it is not necessary, but it retained Linus Torvalds, Linus perhaps a little reluctant, right? File system from the learning perspective, MINIX file system is an excellent starting point, it is simple, but with the main elements of the Unix file system. Based on it, and then learn the mainstream Linux OS file system, such as ext2/ext3, will be much easier (at least this is my learning experience)
