Amen to that.  Not too long ago, I blew about 3 hours trying to debug an odd
networking issue on my laptop - finally tracked it down to the fact that my
IPv4 default route was pointing out the ethernet on the docking station, but
IPv6 was defaulting to the wireless card.  Took a while because I knew *damned*
well that Fedora had long ago included my patch to allow specifying a
preference metric for multiple interfaces, and that I had set it to prefer the
ethernet when both were connected.

Turns out that the patch worked just fine for v4, but nobody ever carried it
forward for v6....

(I probably should cook up a patch for the v6 side.. :)
