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

DESCRIPTION
     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.

Peace,

I submit that "conspiracy" would be an appropriate collective noun for cats.
