> Assuming the dfs commands follow POSIX standards, there are some problems 
> with the DFS du and dus commands. I compared the DFS output with that of RHEL 
> 4u5
> 1. du a file/directory that does not exist:
> Linux: du: cannot access `something': No such file or directory
> DFS: Found 0 items
> 2. dus a file/directory that does not exist:
> - Linux: du: cannot access `something': No such file or directory
> - DFS:  /something      0
