    Hi Jan, 
    
    What is the nature of the access between these nodes and the common
    file system?  Do the nodes mount the file system or ?

    Not sure I understand the above....  Files transferred by HTCondor
    to the Execution Point (compute node) are deposited in the "job
    scratch directory"... For Docker Universe jobs, this scratch
    directory is volume mounted into the Docker container, so Docker
    universe jobs access these files same as non-Docker jobs.
    
    
    Best regards,
    Todd
