I have a small script that uses dhcp6c (from net/wide-dhcpv6) in info-req mode to grab the nameserver from DHCPv6. That means I have to set up DHCPv6 in addition to router advertisements, but I am the administrator of all v6-only networks I have access to so that's not to big of a deal. While setting that up, I noticed a small bug in rtsold. When called as rtsol it does not recognize the -O option. I will cook up a small patch to fix that soon(ish). -- Gregor Best
