40 * (1) string to be matched against runtime machine's sysctl output.
41 * can be either the exact string or a substring contained
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.
59 *
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.
