I just wasn't able to figure out why you didn't already have this file created, nor why my laptop had it but not my desktop. So the story is that 75-persistent-net-generator.rules will call the script when ethernet devices are added, and it is up to the write_net_rules script to generate 70-persistent-net.rules. The problem is that when udev starts very early in the boot process, your root filesystem may still be mounted read-only, preventing this file from being created. This worked on my laptop, because I added module aliases to prevent udev from coldplugging the ipw3945 driver, since it requires a daemon to be running in order to work and that required /var to be mounted. The module is loaded later in the boot process, after all of the filesystems are mounted read-write, and that allowed udev to create the rules file for me, but only for that adapter. The upshot of this is this: by far the easiest way to solve the net-naming problem is to run /lib/udev/write_net_rules all_interfaces This will generate the rules for all interfaces, and then you can just edit the file to change the names as you like. So I guess I'll know that for the next person that asks. :-P -Richard -- gentoo-user@gentoo.org mailing list
