As I learned some years ago, rc.conf is for configuration
variable-setting, not executable code.  Ref. (from rc.conf(5)):

     The file rc.conf contains descriptive information about the local host
     name, configuration details for any potential network interfaces and
     which services should be started up at system initial boot time....

/usr/local/etc/rc.d/* generally contains executable code, though.
