  42  *               within sysctl strings. no "guesses" here, a match should
  43  *               reliably indicate the chassis/icon.
  44  *
  45  *           (2) string describing chassis type divulged by (1).
  46  *               must be one of "desktop", "laptop", "server",
  47  *               "tablet", "handset", "vm", "container" or NULL
  48  *               if only icon string can be ascertained. "vm" refers
  49  *               to operating systems running on baremetal hypervisors
  50  *               (hardware virtualization, like XEN) while "container"
  51  *               refers to OSs running on shared hypervisors like
  52  *               virtualbox or VMware. consider the distinction carefully
  53  *               as common virtualization software like KVM may share
  54  *               characteristics of both "vm" and "container" types.
  55  *
  56  *           (3) string specifying icon to use. follows XDG icon spec.
  57  *               see http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
  58  *               for allowed strings.

  60  *           (4) chassis precedence bit. TRUE if (2) is defined and
  61  *               we're certain it is the proper string. FALSE in the
  62  *               circumstance (2) may be the correct string, unless
  63  *               a match with this bit set to TRUE overrides it.
  64  *               if (2) is NULL, this bit is inconsequential.
  65  *
  66  *           (5) icon precedence bit. see previous definition.
