Mental Ray not creating folders for render passes

[m04arjun]

I have setup and run some .MI files using the mental cloud AMI.
I manged to get it working however run into one serious issue:

1>Mental Ray Standalone cant seem to create folders according to the passes I have setup.It says "no such file or directory".When I run the same .MI file locally,it creates the required folders ,for eg. the AO pass gets rendered and put into the /images/AOPass folder.It does render it into folders which I have to create by hand manually on the instance though,which would be very painful to do for every scene.

2>Command Line Usage :ray -v 4 -file_dir "/root/images" -o "test" layer02.mi

3>It also doesnt seem to take command line overrrides like file_name or start/end.

Is there some flag Im missing,or some lines in .bash_profile,.rayrc etc?

Am enclosing both the .mb file and the .mi file in the attached .zip file.

Regards,
Arjun

Worked out a solution, parsing through the .MI files before job submission and creating directories according to render layers within .MI file.I think Mray standalone cant create folders and subfolders on an EC2 instance.
