     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.
