: because your kern.bootfile still pointed at kernel.old.  the makefile=

: your currently running kernel, both for this reason and to get the

	-thiskernel=3D`sysctl -n kern.bootfile` ; \
	if [ ! "`dirname "$$thiskernel"`" -ef ${DESTDIR}${KODIR} ] ; then \
		chflags -R noschg ${DESTDIR}${KODIR} ; \
		rm -rf ${DESTDIR}${KODIR} ; \
	else \
		if [ -d ${DESTDIR}${KODIR}.old ] ; then \
			chflags -R noschg ${DESTDIR}${KODIR}.old ; \
			rm -rf ${DESTDIR}${KODIR}.old ; \
		fi ; \
		mv ${DESTDIR}${KODIR} ${DESTDIR}${KODIR}.old ; \
		sysctl kern.bootfile=3D${DESTDIR}${KODIR}.old/"`basename "$$thiskerne=

	fi

Seems that way.
