ipv6 autoconf on hosts (non-routers).
to do this,
1. in sysctl.conf, add these lines:
net.inet6.ip6.forwarding=0
net.inet6.ip6.accept_rtadv=1
2. in hostname.foo, add
rtsol
specifying two or more interfaces with "rtsol" may result in strange
behavior - ipv6 spec does not permit multi-interface node to be autoconfig'ed.
