Ubuntu 16.04

[Mikael Abrahamsson]

Hi,

I have a pretty standard Ubuntu 14.04 machine I just upgraded to 16.04, 
which means I get a "4.4.0-21-generic" kernel.

I guess I'm using straight up network manager, because my 
/etc/network/interfaces doesn't mention anything about eth0 or wlan0, only 
lo.

In the GUI, it came default with "privacy extensions disabled".

I used to administrate this device using its EUI64 based SLAAC address, 
which was stable across reboots. Now with 16.04, I get two addresses, none 
of them stable across reboots.

Anyone know what the thought is behind this? I want to continue using 
SLAAC and I'm fine with privacy extension addresses over time, but I want 
a single stable address across reboots.
