After I hand-walked busybox through getting an IPv6 address, everything worked just fine until cloud-init couldn't fetch the instance data, because it insisted on bringing up the interface in IPv4, and there is no IPv4 DHCP on that vlan. - Please work with initramfs and friends on getting ipv6 netboot to + Please work with initramfs and friends on getting IPv6 netboot to actually configure the interface. This may be as simple as teaching it about "inet6 dhcp" interfaces, and bolting the pieces together. Note that "use radvd" is not really an option for our use case.
