That's exactly the point. I _DONT_ want to feed it into any automated 
process to build my application (because all the information is already 
in place, thanks to your constant effort to improve the build 
environment). I just want a place, where EVERY installed RTEMS has 
stored, how it has been configured. And it must _ONLY_ be available in 
human readable form.

I can't speak for Pavel, but _I_ would really only like to store the 
command line. And it will be very useful for _only_ two questions:

- How the hell did you configure this particular RTEMS installed here?

- How can I configure/build/install a newer version of RTEMS to match my 
2 year old previous installation as close as possible

Ok, let's go back to the basics: I see a support request on the mailing 
list. I guess, that the poster has somehow missconfigured RTEMS. Which 
questions can I ask to prove this?
