Detailed Description
Upstream (David) has a new pyparted to be included as part of the standard parted. We have switched anaconda to using this in February.

Chris Lumens and David Cantrell started a rewrite of pyparted to completely expose the libparted C API to Python programmers. It became difficult working with pyparted in anaconda because certain pieces of information were not available and the module would have to be slightly expanded.

The rewrite will come in two phases. The first phase will be reimplementation of the current pyparted API on top of the new _ped module. This ensures an easy transition within anaconda. The second phase will complete the rewrite of the new parted module's classes. Eventually the deprecated API code can be removed.

Both phases are complete, would like to add additional unit tests as time permits.

Benefit to Fedora
Closer to upstream, picks up extensive unit tests that have been added, more maintainable.

Scope
Internal to anaconda's partitioning code. Potentially useful to other projects.

Test Plan
Test that installs can correctly partition in all the currently supported ways. New code also includes extensive unit tests.

User Experience
No change.

Dependencies
Getting the pyparted bits working well enough to do the switch

Contingency Plan
Keep using the old pyparted
