So that actually fixed the issue.  So we have a working example of using CDM and intermediate file storage that Emalayan can use for testing his mosa store set up.

This is not happening as the final output for the file contains only the last line(a Hello from <id> line). I believe this is due to how CDM using symlinks for the files that is matched, so a symlink is being overwritten instead of at the file it points to.  I ran into this problem in the past(but this is documented in the user guide) and just need verify that this is indeed the issue.
