+ * within sysctl strings. no "guesses" here, a match should

+ *
+ * (2) string describing chassis type divulged by (1).
+ * must be one of "desktop", "laptop", "server",
+ * "tablet", "handset", "vm", "container" or NULL

+ * refers to OSs running on shared hypervisors like
+ * virtualbox or VMware. consider the distinction carefully
+ * as common virtualization software like KVM may share
+ * characteristics of both "vm" and "container" types.
+ *
+ * (3) string specifying icon to use. follows XDG icon spec.
+ * see http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
+ * for allowed strings.
+ *
+ * (4) chassis precedence bit. TRUE if (2) is defined and
