I was setting up networking for MAAS and discovered that the device names were ridiculous: bladernr@critical-maas:/etc/udev$ ifconfig |grep HWaddr eno1 Link encap:Ethernet HWaddr ec:a8:6b:fb:9f:66 enx8cae4cff4099 Link encap:Ethernet HWaddr 8c:ae:4c:ff:40:99 In the previous Trusty install on this NUC with the same USB dongle, they were named eth0 and em1. The predictable standard device names.
