When kernel-parameter "ip=dhcp" you can't set stuff like netmask, ip,
or nameservers.

As stated in the commit message, due to current lack of a
env-2 testing environment, I'm not sure how to implement the
following snippet from env-1 in env-2:

diff --git a/defaultenv/bin/boot b/defaultenv/bin/boot

+	bootargs="$bootargs ip=$eth0.ipaddr:$eth0.serverip:$eth0.gateway:$eth0.netmask::eth0::$net.nameserver0:$net.nameserver1"
 fi
