I think this is overengineering. I personally just put few lines in
root's crontab:
?	?	*	*	*	*	make -C /usr/src update' >/dev/null
and /etc/make.conf:
SUPHOST=cvsup?.xx.FreeBSD.org
SUP_UPDATE=	true
SUPFILE=	/etc/site/supfile-rel
#PORTSSUPFILE=	/etc/site/supfile-port
DOCSUPFILE=	/etc/site/supfile-doc
