My system at work seems to take a long time to start the network. I have this suspicion it is waiting for an IPv6 DHCP server to respond (which won't happen).
It looks like the F18 install writes out ifcfg-* files with "DHCPV6C=yes", which should probably not be set by default, especially since so few environments (even IPv6 environments) will have a IPv6 DHCP server. Comment out that line or set it to "no" and it should fix the slowdown.
RA will be more common. That is what I have.

Belts and suspenders: check both.
The ISP's that give you IPv6 addresses (Comcast for one) will also use dhcp to give you a whole 64-bit network of addresses via DHCP-PD.
My ISP gave me a /48 allocation :)
I'm curious how many of the people that are disabling their IPv6 actually have painless access to IPv6 and are ignoring it.
