> Assuming the dfs commands follow POSIX standards, there are some problems with the DFS
mkdir command. I compared the DFS output with that of RHEL 4u5:
> 1. mkdir a directory that exists:
> Linux: mkdir: cannot create directory `test': File exists
> DFS: No output
> 2. mkdir a directory with the name of a file that already exists:
> - Linux: mkdir: `test/one' exists but is not a directory
> - DFS: mkdir: java.io.IOException: Invalid directory name: <home directory>/test/one
