Some tasks involved in the administration of a distributed file system package are the same, whether you are using NFS or some other file system package. The Virtual File System architecture of UnixWare provides a mechanism for administering file system types in a general, or generic, way. Administrators of NFS or other file system types are provided with a common set of commands which can be used to administer NFS (as well as any distributed file system type that may be supported in the future).
In earlier versions of NFS, to make a local resource available, you would ``export'' it, using the exportfs(1Mnfs) command. If you were to run another distributed file system package, keeping the corresponding package-specific commands consistent might be difficult. Multiply this by the number of corresponding package-specific commands in both packages, and the job becomes even more difficult.
DFS Administration provides generic commands that call package-specific commands, freeing you of the need to learn two sets of corresponding commands.
