You may need to make it very visible that there is CentOS under the hood. You need to make available the source to the CentOS bits you deliver to your customer including changes you make. Your application need not be GPL as long as you are 100% the sole author. Give special attention to "derived" work in the GPL. If part of your application is GPL then it may well all be GPL. To simplify your package requirements collect all the CentOS iso images and deliver them to your customer (both source and binary iso images). Then add media for the changes you make to CentOS. Lastly add separate media for the application you are selling. Lastly pay attention to updates and security fixes that you deliver from CentOS or other repo. If the customer does not download them then you have some obligations.... -- T o m M i t c h e l l Found me a new hat, now what?
