There is no way to set a 'preference' for Python 3. Either version of 
Python is pulled into images either through dependencies, or explicit 
inclusion into some package list.

I'm going to move recipes that are dependent on Python 2 to Python 3, 
whenever possible. I'm not porting the upstream code from Python 2 from 
Python 3, just configuring the recipes to use Python 3, when the Python 
code in them has already been ported.

Not sure what you mean here exactly, but if the scriptlets are executed 
by bitbake, then I'm not addressing that.

Again, can you provide an example?

Please start using the question mark (?), so I can see more easily what 
is a question when responding.

Thanks,
