Correct. Hence my reference to "eCos Configuration Tool" rather than 
"ecosconfig" above.

This was a design decision intended to prevent users from modifying 
their configuration to such an extent that it was effectively targetting 
a different board. The eCos Configuration Tool uses the selected 
"Hardware Template" (target) for more than just package selection. For 
example, the "Run Tests" feature requires knowledge of the selected board.
