PLEASE IGNORE THIS !
This post was made late in the night in the middle of frenzied network troubleshooting. I was not thinking stright. It is not possible to configure DHCP for ue0 on bootup, and given the nature of USB Tethering, it is not useful even if it did exist. You will always have the delay needed to go to the phone's GUI and enable tethering. Then your phone will talk to the kernel . And of course, you won't need this all the time, so it makes no sense to wait 30 seconds while ifconfig waits for an non existant ue0.
TL;DR :
So basically it seems as though we aren't able to setup

TL;DR :
So basically it seems as though we aren't able to setup
ue0
for ifconfig_ue0="DHCP"
during boot. But, simply doing a sudo dhclient ue0
lets it work. Why, and what can be done to fix this ?DETAILS :
