Why? I can envision two likely scenarios for using a USB adapter. (a) you need to test something, so you plug in a handy USB adapter and configure it statically. So you're root and mucking about in /etc anyway, so also adding a one-liner to /etc/udev/rules.d/70-persistent-net.rules which names the adapter statically should not be a problem. (b) you're a client (e.g. you configure a new router), likely to use NetworkManager to just run a dhcp client on the adapter or configure a one-off RFC1918 address. So what if the adapter gets a different name next time? Most likely you need to configure a different device in a different '1918 subnet anyway. Or, if you use DHCP, there's no difference either way. In all other situations, quickly configuring a static address is no problem IMHO. > Despite the problems of the MAC-based system that we use currently, the > ifnames method appears way worse to me than what we have now. > On a server, a missed rename due to interfaces showing up in exactly the wrong order makes the system unreachable. Frankly, I cannot imagine anything "way worse" than that. Not in this context. -- -- Matthias Urlichs
