38 * Here we define the NetBSD OS Version in an ELF .note section, structured
39 * like:
40 *
41 * [NOTE HEADER]
42 *	long		name size
43 *	long		description size
44 *	long		note type
45 *
46 * [NOTE DATUM]
47 *	string		OS name
48 *
49 * OSVERSION notes also have:
50 *	long		OS version (__NetBSD_Version__ constant from param.h)
51 *
52 * The DATUM fields should be padded out such that their actual (not
53 * declared) sizes % 4 == 0.
54 *
55 * These are used by the kernel to determine if this binary is really a
56 * NetBSD binary, or some other OS's.
