No, it's not solved. Even if you have persistent names once you install,
if you ever re-image, you're likely to get *different* persistent names;
the first load will always be non-detmerministic.

The only way around this would be to have some sort of screen like:

  Would you like your network devices to be enumerated by

  [ ] MAC address
  [ ] PCI device order
  [ ] Driver name
  [ ] Other

which is just all sorts of fail in and of itself. Especially since
once you get to the point where you can coherently ask this in a
native installer, the drivers have already loaded.
