Description Stefan Assmann 2013-07-26 06:09:45 EDT
Description of problem:
The wired ethernet NIC e1000e on Lenovo T500 laptops is named enp0s25 instead of something useful. I assume it should be em1, right?

Comment 1 Václav Pavlín 2013-07-26 08:01:39 EDT

The names enp0s25 and wlp3s0 reffer to systemd's Predictable Network Interface Names (, so biosdevname is not use at all in this case and they are perfectly ok wrt. mentioned feature. -> Closing as NOTABUG.

Thanks for enlightening me Václav.
