Okay, I've determined the cause of my problem.  The target skeleton  
is not copied into the new root filesystem if the .root file exists  
in the project build directory.  This is to prevent the skeleton from  
being copied to the root filesystem on every build.  I must have  
removed the root directory at some point without also removing  
the .root file.  I think my confusion was exacerbated by the fact  
that the .root file isn't deleted when 'make clean' is run.  I've  
created a patch to remove the .root file when 'make clean' is run.   
Let me know if this is not the proper way to do it, or if there's  
another way to solve it.

Cheers,
Alex
