I discovered this while attempting to install 1.3ALPHA.  I have not seen
this before.  Is it worth send-pr'ing?

(boot single user, or install, without configuring networking)
ifconfig ne1 206.248.33.198
ping 206.248.33.197
PING endplay.inode.org (206.248.33.197): 56 data bytes
64 bytes from 206.248.33.197: icmp_seq=0 ttl=255 time=1.234 ms
ping: failed to clear cached route: Network is unreachable

This problem persists, on all interfaces, until:

ifconfig lo0 127.0.0.1
ping 206.248.33.197
PING endplay.inode.org (206.248.33.197): 56 data bytes
64 bytes from 206.248.33.197: icmp_seq=0 ttl=255 time=1.199 ms
64 bytes from 206.248.33.197: icmp_seq=1 ttl=255 time=1.462 ms
64 bytes from 206.248.33.197: icmp_seq=2 ttl=255 time=1.438 ms
64 bytes from 206.248.33.197: icmp_seq=3 ttl=255 time=1.434 ms
(etc.)


I have installed lots of machines and/or rescued them from single-user by
hand-configuring networking, and this is the first time I've ever had to
configure the loopback device in order to use another interface.
