> If the MAC address isn't a UUID for the device, then *what* is? MAC is technically per system if desired (eg old Sun boxes) and that is quite valid by IEE802.3. In that case you need MAC + topology. If you are running DECnet your system runs on assigned MAC addresses so you also have to be careful to use the EPROM MAC (if one exists which is 99.9% of the time) + topology. > Either people want (a) a name assigned to a specific device (which > implies a UUID like a MAC address stored on that device somewhere > accessible to the driver at plug/boot time), or they want (b) to assign > a name to a *position* on the PCI or USB or firewire or whatever bus, or > they (c) don't care about this at all. I'd argue the fumdamental problem is that I can do this ln -s /dev/sda /dev/thebigdiskunderthefridge but cannot ln -s /dev/eth0 /dev/ethernet/slot0 and the SIOCGIF/SIF BSD style ioctl interface doesn't do pathnames or file handles of network devices. Anyone feel up to putting all the network devices into dev space and fixing the ioctls ;) -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
