[Swift-devel] Mosaswift update

[Jonathan Monette]

I am not sure.  I thought readlink returned the absolute path of the link which is what I wanted to use.  I am not sure how readlink behaves on the compute nodes.  This was my first attempt at getting around the link but I do not think this is working.

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.
