This could be needed, for example, if you want to exactly restart a run from a previous one, but you need to change the barostat variables. If this option is not already implemented in the tools suite of gromacs, it would require some hack of parts of the code, I guess. Any help would be really appreciated.

The variables for Parrinello-Rahman in the energy file are the box
Exact restarts are there so that several shorter runs will give binary
results to one long run. Or to exactly redo part of a run.
When you change a barostat variable the concept of exact restarts does
