title: Yocto, Petalinux 2017.1, SIGGEN_LOCKED_SIGS_T
body: <p>I think this is a more specific Yocto problem so therefore I'm trying Stack Overflow:</p>
  
  <p>During my Petalinux 2017.1 build I get the following warnings for a few packages, all of them in the recipes-core:</p>
  
  <pre><code>The init-ifupdown:do_unpack sig is computed to be cad131d20f065f81a9524376bd7d40bc, but the sig is locked to f2c445306ecd0f9936cc1b9d35a0587e in SIGGEN_LOCKEDSIGS_t-cortexa9hf-neon
  </code></pre>
  
  <p>These scripts are mostly used to substitute config files like /etc/network/interfaces and such. It seems these config files are not changed, so I was wondering if this warning is related.</p>
  
  <p>I did not have this problem in Petalinux 2016.4, so the recipes has been given a run through before.</p>
