Hello,
It's just an upgrade to fedora 20...
but il use a lot of methods to rename ethernet device to eth0... (the same methods in fedora 15, 16, 17 and 18) but NOPE.
I got em1:, I used biosdevname=0, I removed biosdevname package, I change data and files in /etc/sysconfig/network-scripts...
Now I have enp1s0:
and MATLAB is not activated. *%#@!&%£## !!! grrrrrrrrr.
Does any body could help me, please !
Thanks a lot.
Bernard, from France.
PS. Any way, if I have to downgrade to fedora 19, I will do it, but tell me !!

RESOVED
The easiest way to restore the old way Kernel/modules/udev rename your ethernet interfaces is supplying these kernel parameters to Fedora 19:
net.ifnames=0
biosdevname=0
To do so follow this steps:
Edit /etc/default/grub
At the end of GRUB_CMDLINE_LINUX line append "net.ifnames=0 biosdevname=0"
Save the file
Type "grub2-mkconfig -o /boot/grub2/grub.cfg"
Type "reboot"
If you didn't supply these parameters during the installation, you will probably need to adjust and/or rename interface files at /etc/sysconfig/network-scripts/ifcfg-*.
Up to Fedora 18, just biosdevname=0 was enough.
As an example, in a certain machine, in a exhaustive research, I got:
-No parameters: NIC identified as "enp5s2". -Parameter biosdevname=0: NIC identified as "enp5s2". -Parameter net.ifnames=0: NIC identified as "em1". -Parameter net.ifnames=0 AND biosdevname=0: NIC identified as "eth0".
