Except that, as written, it doesn't accomplish the desired goal. It
in order to set slapd=NO. The original version evaluates to "=NO" if slapd
is not set or to "YES=NO" if slapd=YES, neither of which is useful.
I wonder if it might not be better just to modify rc.subr to deal with
an undfined rcvar (treating that as equivalent to NO). Then rc.d scripts
wouldn't be burdened with setting their own defaults. Perhaps an associated
warning message would then be useful as a reminder that the package hasn't
been configured explicitly to run or not to run.
