RHEL 7 Delta rpms.

Last year there was a discussion whether delta rpms should be activated or not by default in the Fedora 22 distribution, whether this feature should be kept or simply removed.

But do you know exactly what delta rpms are? How do they work? What is the default behaviour? Which are the available parameters to change this default behaviour?

To improve your knowledge and decide whether to use them or not, read the delta rpms tutorial.
