   to cater for these systems some fixes were needed.

  +== Flag-files
  +
  +The original script supports influence on its configuration by having the
  +administrator touch certain files before installation begins. This patch
  +extends such approach with more files to touch (e.g. if your environment
  +does not fit the expectations of the existing script).
  +
  +Useful names (relative to the package installation root directory) include:
  +
  +* `/etc/vboxinst_vboxflt` -- install NetFilter (STREAMS) networking module
  +(applicable for illumos)
  +
  +* `/etc/vboxinst_vboxbow` -- install CrossBow networking module (for
  +Oracle Solaris 11 snv_159+)
  +
  +* `/etc/vboxinst_vboxusb` -- force-attempt installation of the USBMonitor
  +module and the USB module (otherwise requires that the script detects that
  +your host kernel is Solaris 11 build 124 or Solaris 12)

   The "downloaded" branch shall contain occasional snapshots of the script
   provided by the upstream VirtualBox downloadable distributions.
  
positive.code: in pre-packaged distributions, be it the original Oracle VirtualBox, or
  any of the OSE builds in illumos distributions.

  ----------------
  
negative.code: The "illumos-fix" is my work in progress as I develop and test the script,
  as well as rebase it to newer upstream versions over time.
  
  The "master" branch is a sort of release variant of the "illumos-fix" --
  whatever seems stable enough to publish and use for everybody daring enough ;)

  Common license for the script is GPLv2 as in VirtualBox OSE.
