title: How to force package to be recompiled on Yocto
body: <p>TL;DR: Is there a way to force to recompile a package every time an image is generated?</p>
  
  <p>I have a bbappend with a <code>do_deploy_append</code> appending to a file and if I modify this step, the recipe will not be recompiled when generating an image using it. This can lead to errors pretty hard to ind. Bitbake assumes it has been unchanged. I have only 2 packages like this, very small. </p>
  
  <p>Is there a parameter to force those package being cleaned and recompiled without manually do it?</p>
  
  <p>I am using Yocto morty</p>
