I don't think that step (1) and (2) really matter.

It's strange that this works but that assigning the hostname to be
"localhost" via "/etc/hostname" is different than having it assigned
by "/etc/init/hostname.conf". Maybe the "-b" switch allows dhcp to
override "localhost".

Out of curiosity, what's the output of "cat /proc/sys/kernel/hostname"
with your new setup?
