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:
=2E..
=2Eif !exists(${DESTDIR}/boot/loader.rc)
${INSTALL} -C -o ${BINOWN} -g ${BINGRP} -m 444 \
${.CURDIR}/../../forth/loader.rc ${DESTDIR}/boot
=2Eendif

Nope, mergemaster(8) deals with updating of /etc only, unless
I'm horribly mistaken (I don't use it personally, but pretty
much do what it does manually).
