for clarity - none of the network configs were passed via the command
line.  Therefore, none of the setup as described worked (outside of
using the extra parameter as you described)

some reference to leaving it blank may work as well (untested):
ip=<client-ip>::<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>
