One remaining corner case is NFS/IPv6 root, whereby userland won't have 
a chance to start before the network, and hence may miss the solicited 
RA. Or would it? By default, the next unsolicited RA can be anytime 
from now to after 10 minutes, so that's not sufficient. I wouldn't 
personnaly care, but...
