we (ISC) asked KAME about this, and they suggested:
% cat /etc/start_if.nge0
ifconfig nge0 inet6 fe80::1
...which for freebsd 5.2.1 at least, has the right effect. rtsol still runs,
and once the upper 64 bits are known, the obvious thing happens:
% ifconfig nge0 | grep ::
inet6 fe80::1%nge0 prefixlen 64 scopeid 0x5
inet6 2001:4f8:3:bb::1 prefixlen 64 autoconf
...so it's not as easy as the solaris "token" thing described earlier in this
thread, but it actually works fine and it's become universal on ISC's hosts.
