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 (http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/), 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.
