em1 instead of eth0?

Since a little while, few machines using "biosdevname" started appearing.
One of the consequences of having em1 instead eth0 for part of the autoyast autoinstallation process is to end up with a machine without network at the end of stage 2.

If you are one of the lucky owners, make sure to append "biosdevname=0" so to get rid of once and for all of the em device.
