I thought you were going to bbappend this instead of overlaying the whole recipe.

I always had issue with this.  I'm not sure that this statement holds true because whether a new SRCREV will cause a rebuild would depend on whether that SRCREV sorts higher than the old one.  Unless something else has changed.  This is useful though if you want to know what SRCREV was used for a build.

That being said if you were going to overlay this recipe the PR should be something like

PR = "${INC_PR}.0"

Right now you are appending to the default since PR is not defined.  With a bbappend you should append a -arago flag.

So this comes back to why no bbappend?  Is it because the base version in oe-core is 2.4.39 and not 2.4.41?  Can you not append the _git version of the recipe and update the PV appropriately?
