Paul began working to address the package feed churn issue some time
back using the tool build-compare from the openSUSE project.

You can find links to various trees and a summary of the progress so
far in this bugzilla entry:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=8318

It still needs some more work; most notably I'd like to see some tests
that validates the functionality.

Regards,

Joshua
