Does the kernel create global scope addresses? Maybe it does in some
more advanced IPv6 environments, but it seemed like excluding global
scope addresses in checkpoint meant that we only saved (and thus
restore) the permanent ones anyway.
I guess it's a better idea to just save the flags anyhow now that I
have a way to restore them.
