Sails js - how to properly throw out grunt watch in staging environment?

Question

Grunt.js

So, in a typical sailsjs project, there are tasks/register/prog.js for the production environment and tasks/register/default.js for everyone else. I also have a staging environment, which should be like production, just hangs on a different port and deploys from another branch.
The problem is that default.js is used there, so the grunt watch task hangs and eats the processor. What needs to be done so that my staging is like production, and not like development?
