Log:
  Set a default hostname for virtual machine images.
  
  A recent bug in security/sudo causes segmentation faults when
  the system is not configured with a hostname, which causes issues
  with some virtual machine setups, notably Vagrant.  Set the default
  hostname to the output of 'uname -o'.
