My first simple solution that actually worked was to wrap the standard bacula-fd init script with my own as follows:

#!/bin/sh

/etc/init.d/bacula-fd $*
result=$?
echo $result
if [ $result -eq 4 ]; then
	result=3
fi

return $result

It's not elegant, and it possibly masks other errors, but heartbeat no longer complains that it can't monitor the bacula-fd.

I may  hunt for a sample template to create an OCF Resource if this simple solution doesn't work or someone can tell me why my solution is a very bad idea.

Thanks again,
