>Description:
This is the THIRD time I've tried to report this. mail.n.o appears to be eating my prs.

After the giant commit:
Subject: CVS commit: [netbsd-8] src
From: "Soren Jacobsen" <snj%netbsd.org@localhost>

I can no longer "ping6 www.kame.net". I also notice that I can't get routes when I run "sudo dhcpcd -dB6T --nodhcp6 wm0".

I used the git mirror and reverted the change and everything works.
