Licencing query

Greetings, I had posted this query a week back, but didnt receive any responses, I hope to get some replies this time. I had a query on the Yast License. I have read the license and to my understanding it means this. We can redistribute the SuSe Linux (along with Yast) if we are giving it monetarily free, but if we are selling the product then we need permission from SuSe Linux. Am I correct at my understanding. Please enlighten me. Regards. -- "Even a bumper crop may not help farmer have high yields, if there is delay in harvesting"
