I think what's most likely happening here is that your IMAGE_INSTALL += is 
actually overriding the value because a statement parsed later that sets the 
default value of IMAGE_INSTALL is doing it with ?=, and since the value was 
already set it doesn't include any of the defaults. You can confirm this by 
using bitbake -e your-image | less and searching (with / ) to find 
^IMAGE_INSTALL - above that line you will find the history of how the variable 
got set. If that is the problem, use IMAGE_INSTALL_append, or better still 
create your own custom image recipe and then you can completely specify the 
value of IMAGE_INSTALL.

Cheers,
Paul
