FWIW, I've made the same mistake thinking that "inet autoconf" and
"dhcp" are functionally equivalent.
I based the assumption both on the commit message[0]:
The flag can be set by "ifconfig $if inet autoconf" or by
adding "inet autoconf" to /etc/hostname.if. An existing
"dhcp" line should be removed.
i.e. no mention of additional "up"; and the fact that "up" is already
implied when "dhcp" is being used.
I can understand both sides to the argument, i.e. on the one hand
you can configure several interfaces without bringing any of them
up; or why would you configure an interface if you don't want to
use it, not to mention one command less to run or one less option
to use in hostname.if(5), on the other.
