It's easy to use instances of sharing configurations in IDEA - just create a configuration and check the Share box:

I already manage the versions of the files in .idea/runConfigurations(in the corresponding project) and part ~/.IntelliJIdea*(for the puppet desktops). However, I cannot find where the IDEA saves the default settings - it does not seem to be in any of these places. Obviously, they must be somewhere in it, because it works through reboots. The official documentation is unusually useless in this case:
This check box is not available when changing the default settings for starting / debugging.
In the particular case, I want all future Behave configurations to have an environment variable DISPLAYset to :1to run browser tests in VNC, and not in the foreground.
