(NetworkManager-0.8.0-10.git20100502.fc12.x86_64)

In a network with SLAAC and RDNSS-in-RA (no DHCPv6), the nameserver jumps in and out of /etc/resolv.conf.  My radvd.conf is as follows:

> interface eth0 {
> 	AdvSendAdvert on;
> 	MaxRtrAdvInterval 30;
> 	prefix 2001:16d8:ee47::/64 {
> 		AdvAutonomous on;
> 	};
> 	RDNSS 2001:16d8:ee47::5:1aac {};
> };

I'm attaching a log from activating a wired ethernet on my test host.  2001:16d8:ee47::5:1aac showed up in /etc/resolv.conf immediately following the device activation, but it disappeared at 07:50:01 (leaving only the DHCPv4-learned name server in there).  At 07:50:17 a RA was received, and this caused the IPv6 name-server to be re-added.  This seems to happen constantly - at 07:50:47 it also disappeared and at 07:50:17 it reappeared (following the receipt of a RA).
