  +After updating the host software, if you're using the PUEL-licensed extension
   pack, don't forget to update it as well. A nice automation was posted on the

  = Applying and using the patch to (un)install a VirtualBox package
  
  There are two approaches: partially install the unmodified package, fail
  in the configuration step on an unsupported OS, patch the installed script
  and resume configuration to complete the installation, or to fix the SVR4
  package file. The former is more simple in practice, while the latter is
  more suitable for distro maintainers or LAN admins who want to suffer the
  complicated procedure once per upgrade, not once per host.

  NOTE: Thanks to "russell" from the OpenIndiana mailing list for pointing
  in the right direction for this simplified procedure.
