F21 Interface renaming

[Weiner, Michael]

I am running a Fedora 21 workstation, and I am trying to run Schrodinger software package
which requires a license and a 'flexnet' type of license manager. The issue is
that the it expects to bind with ethXX which we all know is not the default naming
convention any more. Great, ok, I google and fine some tips about renaming:


1)      append "net.ifnames=0 biosdevname=0" to /etc/default/grub
GRUB_COMMAND_LINUX   (doesn't seem to have any affect)

2)  ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules  (which doesn't exist on
my system)

3)  /etc/udev/rules.d/70-persistent-net.rules   (file doesn't exist, in fact
/etc/udev/rules.d is completely empty)

4)  Removing biosdevname  (which of course doesn't exist on this system)

and of course renaming the config files and changing the 'Name' in the files. I
reboot, and no matter what I do it refuses to work, ifconfig still lists the old device
names, and 'ifconfig eth0' fails and complains that the device doesn't exist.

Any known good working solutions or a direction to try?

Thanks in advance
Michael
