Naming
DNF stands for Dandified yum. Since DNF is a tech preview in Fedora 18 the Python module names can not be 'yum.*' as that would clash with yum itself.
Why not zif/zypp?
People are asking why we didn't choose to adopt zif (or SUSE's zypp) instead of fixing yum. The reasons are:
dnf looks for a middle ground between a sane API and some backwards compatibility.
dnf and hawkey are first steps toward using the same resolver across the entire stack.
Libsolv is a well tested and proven code base, currently the most sophisticated and optimized dependency solving implementation.
Benefit to Fedora
Hawkey clients will get:
easier bindings to other languages than Python
concise, clear package management API
better performance (through utilizing libsolv)
The set of possible hawkey API consumers:
dnf (the next generation yum)
release engineering tools
PackageKit
graphical package management tools
Anaconda
DNF clients and users will get:
Faster and simpler package manager.
Simplified client code.
