	I agree.

	And to disable '@unexec %D/etc/rc.d/isc-dhcpd forcestop', I wrote
	/etc/rc.conf.d/dhcpd in my machines like following:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
stop_precmd="nothing_to_do"
nothing_to_do () {
	[ x"${rc_force}" = x"yes" ] && exit 1
}
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	If needed, we (administrators) can disable a mechanism such as thus.
