configure command line in installed directories?

[Thomas Doerfler]

Ralf and others,

I have been silent in this thread for two days, because I really had to 
calm down. I think I am calm enough to answer again ;-)

Yes, I definitively did. But I think that when using RTEMS you will 
almost always have these three steps intermixed. AFAIK the things 
Gaisler is doing are more or less unique. They ship a selected and 
properly configured version of RTEMS matching their customers needs. And 
if I have problems with their distro, I can call them.

But from my understanding there are very few properly 
integrated/configured/packaged distros of RTEMS right now (although this 
may be the goal for the future).

Currently, most projects using RTEMS have to start working from the 
source code package, and at least in 20% of the projects I asume that 
configuring RTEMS, installing it and checking it with the application is 
an incremental process.

In your responses you mentioned somewhere, that configuring RTEMS 
properly is the job of the system integrator. I agree (and that is 
exactly the model I assumed). But:
- What if he did a poor job.
- What if he did not document properly what he did?
- What if he is ill or on holidays?
- Or fired (because he did a poor job)?
- Or he simply did not (yet) realize that it would be a good idea to 
store the configuration?
- Or just did a quick tryout of a certain configuration which works 
surprisingly well an after a week he has no idea which of the ten tries 
was the right one?

I only see few harms in my recommendation:
- we will consume about 1KByte more space in the installed directory
- we have to generate/store/install the information somehow.

Thomas.
