Good to have:
-------------
- Make it work for all arches.  Involves downloading from secondary arch kojis
- Make it do the install for the user.  Tie into yum to do this, etc.

Pie-in-the-sky:
---------------
- Once a koji build is narrowed down, build a vanilla kernel of the same
  NVR to rule out Fedora patches.
- If the vanilla build fails, have it do an actual git bisect.
