[split] Maintaining config.txt

[adrii]

Hi Tim

In config.txt, if user settings come after Moode settings then they can override them. It seems like the options are:

• put user settings in a separate file and include it last in config.txt, but then raspi-config changes (which I imagine will occur even if unnecessary) might be added both before and after the include statement
  
• put Moode settings in a separate file and include it first in config.txt, then any settings in config.txt are user settings (including changes made by raspi-config) and always come after Moode settings.
  

The second option seems better from the point of view that it ensure that user settings come after Moode settings. However, there may be other aspects to consider, and I don't know all the details of the config system.

Adrian.
