I'm not sure why one would want to autoconfigure eth0 in this case?

Changes in radvd 0.7.1 probably kill this approach (if "all") is used -- 
radvd will not start unless "all" forwarding is enabled.

Having conf/eth0/forwarding=0 is effectively a DoS for the clients for the 
period it's 0, but in simple scenarios this may not be a problem.
