That would be an option too. I could easily deal with 2 filesystems. But 
how do you build the second (user) project? It seems you need to 
duplicate almost all settings in the second config file. And that is 
very error prone in my eyes.

Shouldn't it already be possible to do something like this;

OS project create ptxdistconfig and platformconfig

Than in the user project include the OS ptxdistconfig and platformconfig.

But how to tell the user project not to rebuild everything again. That's 
my main problem.
