LINUX目录详解
根文件系统一般应该比较小,因为包括严格的文件和一个小的不经常改变的文件系统不容易损坏。损坏的根文件系统一般意味着除非用特定的方法(例如从软盘)系统无法引导,所以不应该冒这个险。
根目录一般不含任何文件,除了可能的标准的系统引导映象,通常叫/vmlinuz 。所有其他文件在根文件系统的子目录中。
-LINUX Comments on the root directory system in general be relatively small, because including strict documentation and a small change of the regular file system is not easy to damage. Damage to the root system generally means that unless you use a specific method (for example, from floppy disks) system is unable to guide, they should not take the risk. Root directory generally do not contain any documents, with the possible exception of the standard guide mapping system, usually called/vmlinuz. All other documents in the root file system subdirectories.
