# This doesn't reliably trigger. It's a rare race condition, on some machines it always works, on others it's # maybe a 1:20 chance it doesn't work. Apparently udev tries to remember whether a device was already handled # by systemd and ignores further add events. So if you think this problem doesn't exist anymore, make sure # you're not just lucky and not hitting this issue, and also make sure you understand what the initial problem # was. I assume it's something to with switching from initrd to final root, but this isn't worth the effort tbh. #ACTION=="add", SUBSYSTEM=="net", KERNEL=="br0", TAG+="systemd", ENV{SYSTEMD_ALIAS}="/sys/subsystem/net/devices/$name", ENV{SYSTEMD_WANTS}="network-interface@$name.service" # So use a more crude approach that triggers every time (consecutive invocations shouldn't do anything) ACTION=="add", SUBSYSTEM=="net", KERNEL=="br0", RUN+="/bin/systemctl --no-block start network-interface@$name.service" # Also don't match br-nic-* here, it's conditionally started via systemd-bridge_additional_nics
