Fedora 15 Changes Network Device Naming Scheme 132

dkd903 writes "Fedora developer Matt Domsch has announced that Fedora 15 is breaking the conventional ethX naming scheme used for Ethernet devices by adopting a new scheme called Consistent Network Device Naming. The ethX naming scheme works fine as long as the system has only one Ethernet port. However if there are more than one Ethernet ports, the actual problem starts."

    <rant>this is why I don't like the /dev/sd* interfaces in Linux - you have to dig deep into /proc to find out which port SATA and SAS devices are on</rant>

    Take a look at /dev/disk. You should find what you're looking for there.

    So tell me, when, on a reboot, we cannot make sure that 'eth0' will remain 'eth0' if we have more than one ethernet device? Bullfish to the n-th factor. The boot strapping in /etc/init.d/network has MORE than compensated for this for years in any RedHat-related or spin-off distro I've been working with. For any sort of persistent device naming you can use udev rules (can be a bit over learning overhead so you don't trump rules or get your rules to work the way you want them to) or hack out one of the ifcfg-eth* network device scripts and edit the HWADDR parameter with the MAC address of the ethernet device you want to hard-line to that device name.

    To the articles defense, the new naming scheme does make sense, but regardless, it's just that: over engineered and way more complicated than it needs to be. If it isn't broke, don't fix it. And furthermore, don't call something broke when it's not.

Recent investments will yield a slight profit.
