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. | |
