Public bug reported: Installing biosdevname can result in a system that will not have working networking on reboot. I think there should be a warning / dialog when the package is installed that warns users they need to do further system configuration after installation.
biosdevname creates a udev rule /lib/udev/rules.d/71-biosdevname.rules. This can override any existing udev naming for an ethernet device, particularly one in /etc/udev/rules.d/70-persistent-net.rules that comes from a legacy install. In practice, what this means is that after installing biosdevname the Ethernet device may be named something like /dev/p4p1 instead of /dev/eth0. After installation the user has to manually edit /etc/network/interfaces to have a working network on reboot. I believe the code is all working correctly, but it'd be a kindness if the biosdevname installer detected the potential system breakage and warned the user. I don't believe there's any warning at all that installing this package can break the system at reboot. (My story: I upgraded a working Ubuntu 10.10 system to 14.04 via do- system-upgrade. Then I stupidly and blindly installed biosdevname because some other Ubuntu 14.04 new install I had had that package. When I rebooted, I could no longer access my Ubuntu box over the network. Since the system was 1500 miles away and without a network console, that was a bit awkward.) $ lsb_release -rd Description: Ubuntu 14.04.1 LTS Release: 14.04 $ apt-cache policy biosdevname | grep Installed Installed: 0.4.1-0ubuntu6.1 See also: https://bugs.launchpad.net/serverguide/+bug/1312785 ** Affects: biosdevname (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1382600 Title: Installing biosdevname should warn about required network configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/biosdevname/+bug/1382600/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
