message:
  Added an hook mecanism in order to dynamically patch virtual machines built (and installed) after July 2013. When the user selects a machine, for instance `machine-debian-wheezy-42007', marionnet searches for a related file ending with the suffix ".relay", for instance `machine-debian-wheezy-42007.relay'. If such file is found, marionnet makes a copy of this file into the guest directory /mnt/hostfs/. In this way, the file will be sourced as final step of the script `/etc/init.d/marionnet_relay' during the bootstrap process of the virtual machine. Example: if a new feature that requires the existence of /dev/tty12 on VM is developed in marionnet but our `machine-debian-wheezy-42007' doesn't have /dev/tty12, we can simply create a file `machine-debian-wheezy-42007.relay' with the following lines:  
  ---
  [[ -e /dev/tty12 ]] || mknod /dev/tty12 c 4 12
  chown -v root:tty /dev/tty12
