Some improvements I'd like to suggest please:

* Put this in the image .bb file, we don't need a generic class for 
  this in the core, at least at this point
* Don't import things you don't need (logging, sys)
* Use something like 'if "x11" in packages' instead for that for loop
* Use SkipPackage instead of bb.fatal like I suggested (grep will show 
  some examples)
* Use True instead of 1
* Rename the variables to be meaningful (packages is confusing here)

Cheers,

Richard
