Dude wrote:DTrace is Open Source, Ksplice is not. DTrace however is licensed under the CDDL, not the GPL. Neither of them fit into the GPL licensing directly, nor the tasks of the Linux Foundation. I'm not entirely sure what you're asking, though. DTrace and Ksplice are additional value-added components that are available to Oracle Linux support subscriptions. However, neither of them are required or distributed with Oracle Linux itself, and thus neither of them are required to be licensed under the GPL.
Some of the Oracle Linux enhancements, such as Dtrace and Ksplice require a ULN support subscription. It seem obvious that not all Oracle enhancements are freely available. Are Dtrace and Ksplice open source projects? How does it fit into GPL licensing and the tasks of the Linux Foundation?
I'm not entirely sure what you're asking, though.Well, I guess I don't really expect to receive an answer for the following, but I was wondering:
Dude wrote:Could Oracle? Sure. Would Oracle? Probably not. :) Oracle Linux support is already significantly cheaper than any other Enterprise Linux support vendor, and we provide lots of value-added components in your support subscription at no extra cost: something that no other vendor does. Also, we provide production support for btrfs in the core Oracle Linux product, so it's very unlikely we'll ever port/distribute ZFS to Oracle Linux.
Now since Dtrace, Ksplice, and also ZFS are owned by Oracle, couldn't Oracle just provide all these and future enhancements for a free subscription? I understand Oracle being a business needs to make profit, but are paid support subscriptions to allow customers to use exclusive or new technologies the best strategy, especially in Linux?
