The RFC says that you shouldn't add a LLA address to an interface that already is configured with a routeable address. Configuring LLA via rc.conf should probably be done like DHCP, by using a magic word in the ifconfig_ifX-line. We could have two words, one called LLA that would run in the "forced" mode and another LLA2 (I can't come up a good name) which would run in the RFC compliant way. Fredrik Lindberg
