I hacked up a solution for service(8):

http://bsd-geek.de/FreeBSD/service.sh.enable-disable.patch

The patch adds the following directives to service(8):

enable: Grabs an rc script's rcvar value and runs "sysrc foo_enable=YES"
disable: The opposite of enable
rcdelete: Deletes an rc script's rcvar value from /etc/rc.conf using
          "sysrc -x foo_enable"

The nice thing about is that you can use one of the new directives on
one line with the old ones, as long as the new are the first argument:

# service syslogd enable
# service apache24 disable stop
# service apache24 rcdelete stop
# service nginx enable start


So after installing a package, to start and enable a daemon permanently
all you have to run is
# service foo enable start
