Given I expect CSPs will have to add-in specific version support for their own special version-pair needs, I think it would be helpful in the long run to have a tool that reported what versions a kernel build wrote and parsed. Test-to-learn the same information sounds a bit too difficult. Something with ELF is probably how to do that, but I don't imagine a use in a runtime check consuming this information. Jason
