Bear in mind the conditionals of make(1) and sh(1)?

But you don't often know if installworld attemps to install it
or not, if it wasn't here:

src/sys/boot/i386/loader/Makefile:

beforeinstall:
...
.if !exists(${DESTDIR}/boot/loader.rc)
	${INSTALL} -C -o ${BINOWN} -g ${BINGRP} -m 444 \
		${.CURDIR}/../../forth/loader.rc ${DESTDIR}/boot
.endif
