title: After devtool build image, files can be found in rootfs, but not found when I run on QEMU
body: <p>I used <code>devtool build-image</code> to include recipe in workspace.</p>
  
  <p>I found corresponding files in rootfs, but couldn't find files when I use QEMU to mount image.</p>
  
  <p>Here's what I done.</p>
  
  <ol>
  <li>clone openBMC</li>
  <li><p>build image for meta-evb-ast2500</p>
  
  <pre><code>export TEMPLATECONF=meta-evb/meta-evb-aspeed/meta-evb-ast2500/conf
  . openbmc-env
  </code></pre></li>
  <li><code>bitbake obmc-phosphor-image</code></li>
  <li>successful</li>
  <li><code>devtool add bbexample https://github.com/whbruce/bbexample.git</code></li>
  <li><code>devtool build-image obmc-phosphor-image</code></li>
  <li><p>files could be found in fs</p>
  
  <pre><code>$ find tmp/work/evb_ast2500-openbmc-linux-gnueabi/obmc-phosphor-image/1.0-r0/rootfs/ -name '*bbexample*'
  tmp/work/evb_ast2500-openbmc-linux-gnueabi/obmc-phosphor-image/1.0-r0/rootfs/usr/bin/bbexample
  tmp/work/evb_ast2500-openbmc-linux-gnueabi/obmc-phosphor-image/1.0-r0/rootfs/usr/lib/libbbexample.so.1
  tmp/work/evb_ast2500-openbmc-linux-gnueabi/obmc-phosphor-image/1.0-r0/rootfs/usr/lib/libbbexample.so.1.0.0
  </code></pre></li>
  <li><p>start QEMU</p>
  
  <pre><code>qemu-system-arm -m 256 -M ast2500-evb -nographic \
  -drive file=$(ls tmp/deploy/images/evb-ast2500/obmc-phosphor-image-evb-ast2500-*.static.mtd),format=raw,if=mtd \
  -net nic \
  -net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443,hostname=qemu 
  </code></pre></li>
  <li>These files were not found</li>
  </ol>
  
  <p>These files should have been included in image, right?</p>
  
  <p>Something wrong?</p>
