This patch marks the beginning of steps that would
lead to clean and easy split of the configuration
file. Common portion can then be re-used by other
configurations.

 Since the patch changes most of the file contents, it may
 not be easy to review. This sequence on individual patches
 that were squashed to make this change can be viewed at:

 Since, this was a set of patches with no real change in
 functionality, i didn't post them to the list.
