Under Arch Linux, your network cards are sometimes named differently between two reboot. Configuring your network connection is hard if you don’t know if you card will be called eth0 or eth1.
A file /etc/udev/rules.d/75-persistent-net-generator.rules.optional can be used to tell udev to generate persistent network rules.
It’s very simple:
mv /etc/udev/rules.d/75-persistent-net-generator.rules.optional /etc/udev/rules.d/75-persistent-net-generator.rules
Reboot your system. A /etc/udev/rules.d/70-persistent-net.rules file has been generated. Now you can disable the generator:
mv /etc/udev/rules.d/75-persistent-net-generator.rules /etc/udev/rules.d/75-persistent-net-generator.rules.optional

I had an issue with interface renaming right after Fedora 14
installation.
The funny thing is :
arch-x86-2.cisco.com:2> pwd
/etc/udev/rules.d
arch-x86-2.cisco.com:3> ls
40-hplip.rules
70-persistent-cd.rules
90-hal.rules
56-hpmud_support.rules
70-persistent-net.rules
91-drm-modeset.rules
60-fprint-autosuspend.rules 85-pcscd_ccid.rules 97-bluetooth-serial.rules
60-sysprof.rules 90-alsa-tools-firmware.rules 99-fuse.rules
arch-x86-2.cisco.com:4>
70-persistent-net.riules exists
70-persistent-netgenerator.rules DOES NOT!!!!!
Why ? Who created the former file?
In some Linux distros, the net generator file is at
/lib/udev/rules.d/75-persistent-net-generator.rules
I don’t really know.
It must have been generated during your first archlinux install ?
You should look at the content of your persistent-net.rules file.
Apparently there is a bug in it if after your fedora install the interfaces where renamed.
