This is the easiest way to handle this. Another way would be to put this
file in the path relative to the application. That way, DMTCP will try to
use the relative path if the abspath is not found.
- Perhaps a dmtcp plugin that would transform the name? Is that possible?

That's a good idea but with a catch. Atleast in the current svn, I am not
sure how easy would it be to integrate the plugin. The hardship comes
mainly due to shared file descriptors. In case of non-shared file
descriptors, we can put some hooks to enable us to write the plugin.
