I'm in no hurry to get to 2.60-final. There are no pressing problems 
with 2.59, and a lot of touched code on 2.60, so we'll take it slow and 
try and get it right. It's amazing how the bug-report rate has increased 
since rc1 though :-).

I'll fix those problems for the next RC, Matthias. Thanks for that.

A question: does the BSD network stack always fix the prefix length at 
exactly 64 bits? That's the "correct way" and as I can't find a way to 
read the prefix length from an interface in *BSD, I've assumed that it's 
always-and-forever 64. On Linux it's possible to set a longer prefix 
length on an interface and dnsmasq handles that. I know a subnet should 
be 64 bits, but one advantage of DHCPv6 is that you don't need 64 bit 
subnets for stateless addressing to work,  and I foresee a lot of people 
getting /64s from an ISP and then subnetting them.


Cheers,

Simon.
