At a very basic level, "inet autoconf" is a signal to something running in the background and other startup proceeds right away, whereas "dhcp" is "run a program and wait until either the address is configured or times out" (which is behaviour some people want). > 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.

For the hostname.if case, it's easy enough, netstart could do "up" automatically after configuring if there is no "down" in the file.
