rc.conf is "sourced" by rc.subr. In other words, it's a shell script.
You can thus set it up so it sets some variables when called from
heartbeat and others when called by boot. For example, you can set an
environment variable by heartbeat (or by a script that heartbeat
calls...) and judge from that.
