This isn't how PACKAGE_EXCLUDE was really intended to be used. It's telling 
you that you've effectively explicitly said "install this thing" then you've 
said "don't install this thing". PACKAGE_EXCLUDE was meant to remove (or at 
least error) a package implicitly installed through dependencies.

I have to be honest and say I think that image recipes are a special case and 
should be more or less disposable - if you need to modify them, rather than 
using a bbappend, just copy and modify as needed.

Cheers,
Paul
