Yup, rtadvd can autoconfigure itself by querying ifconfig'ed prefixes
in the kernel by doing SIOCGIFPREFIX_IN6 (basically similar to
doing SIOCGIFCONF). you can leave /etc/rtadvd.conf unedited in

Yes, that is the reason. for example, pkgsrc/net/zebra can configure
interface address in its configuration file. The change will be
reflected into the kenrel and then reflected to rtadvd.
(I personally try to keep router configuration more static,
so I don't use this feature much)
