I was going to commit something like the following to pkg/INSTALL.
Would this suffice?

#!/bin/sh
#
# $NetBSD$

PKGNAME=$1
STAGE=$2

case ${STAGE} in
PRE-INSTALL)
	;;
POST-INSTALL)
	ETCDIR=/etc/netatalk

	mkdir -p ${ETCDIR}

	echo "Installing configuration files:"
	for file in \
		AppleVolumes.default \
		AppleVolumes.system \
		atalkd.conf \
		papd.conf
	do
		if [ ! -f ${ETCDIR}/${file} ]
		then
			echo "	${file}"
			cp ${PKG_PREFIX}/share/examples/netatalk/${file} \
				${ETCDIR}/${file}
			chmod 644 ${ETCDIR}/${file}
		fi
	done
	echo "done."

	if [ -f ${PKG_PREFIX}/etc/atalkd.conf ]
	then
		cat << EOF

You may want to merge the configuration files in ${PKG_PREFIX}/etc from a
previous installation of netatalk with the files in the new netatalk config
file directory ${ETCDIR}.
