Thank you hadmut for taking the time to report this bug and helping to make Ubuntu better. It seems this was missed in the Christmas time :-/
I currently can't find a matching bug, but I'm pretty convinced I've heard most of the context before in discussions around networkd/netplan. It is somewhat related to the old discussion in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673490 (in regard to the layering violation), but that is not what I'm looking for. Until I find the discussion I could link I'll mark it as confirmed for now. But this always is a topic with a huge complexity due to the interdependencies of the tools. ** Bug watch added: Debian Bug tracker #673490 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=673490 ** Changed in: bridge-utils (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bridge-utils in Ubuntu. https://bugs.launchpad.net/bugs/1652269 Title: udev script shortcuts ifup-scripts Status in bridge-utils package in Ubuntu: Confirmed Bug description: Hi, I just ran into a problem. I've configured a bridge as a virtual lan (for lxc, lxd, and these things), but also configured an USB Ethernet dongle to be part of the bridge. If the dongle is present at boot time or if the dongle is put in while the bridge is down, then /lib/udev/bridge-network-interface tries to take the bridge up. Nice. But it does not call ifup, instead it directly calls IFACE=$port /etc/network/if-pre-up.d/vlan This ifup is not aware that the interface is up and still thinks it would be down, and all the other settings (up/down-scripts ...) are not executed. Breaks functionality (and can be a security problem, since firewall settings my be skipped.)
