title: run chroot within docker
body: <p>I've a commercial app, that is shipped in a chroot environment : the startup script is making the chroot, and starting the exe.</p>
  
  <p>The App is pretty complex, and also for support purposes, I don't want to change the all environment.</p>
  
  <p>Is it possible to run chroot, and start the service in docker ? Or are the two incompatible ?</p>
