	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
	some cases.

	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)
