It always puts the process entry point (_start) at address 0x00000000. This gives us valid memory (a zero-byte string, since the first two bytes of procedures like _start on VAX (those called with "callg" instr.) are the saved register-mask, and in _start's case this is zero (does not matter). Furthermore, this line in kern_exec.c checks if: if (ap == NULL && uap->envp) { uap->argp = NULL; ... } So we don't need a valid argv at address zero.
