Using the same bsd.rd's:
$ cat ifconfig.bad.dhclient
vio0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 96:00:00:34:06:8e
llprio 3
groups: egress
media: Ethernet autoselect
status: active
inet 95.217.7.62 netmask 0xffffffff
$ cat ifconfig.good.dhclient
vio0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 96:00:00:34:06:8e
llprio 3
groups: egress
media: Ethernet autoselect

inet 95.217.7.62 netmask 0xffffffff

$ cat ifconfig.bad.-soii
vio0: flags=408843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,INET6_NOSOII> mtu 1500
lladdr 96:00:00:34:06:8e

I think AUTOCONF4 is missing because it wasn't added until July (from my
reading of the commit logs), so the images under test, being built from
commits in May, just don't contain that code yet :)
I can of course repeat any of these tests on a -CURRENT system vs. a
-CURRENT system that has the commit that introduced the problem
reverted, if you like.
