Add the following option to the kernel configuration file:
# This allows you to actually store this configuration file into
# the kernel binary itself, where it may be later read by saying:
# strings -n 3 /boot/kernel/kernel | sed -n 's/^___//p' > MYKERNEL
#
options INCLUDE_CONFIG_FILE # Include this file in kernel
Then add the following to the kernel module port:
BOOTFILE!= sysctl -n kern.bootfile
.if !defined(KOPTION_KSE)
. if ${OSVERSION} > 700040
#KOPTION_KSE!= if ${SYSCTL} -b kern.conftxt | grep KSE ; then echo "yes" ; fi
KOPTION_KSE!= if config -x ${BOOTFILE} | grep KSE ; then echo "yes" ; fi
. else
KOPTION_KSE!= if strings -n 3 ${BOOTFILE} | grep KSE ; then echo "yes" ; fi
. endif
.endif
.if ${KOPTION_KSE} == yes
CFLAGS+= -DKSE
.endif
