stop on net-device-removed INTERFACE=$INTERFACE should be stop on net-device-remove INTERFACE=$INTERFACE Furthermore, the DRIVERS var is not filled when the device gets plugged (add action), resulting in an infinite amount of entries in /etc/udev/rules.d/70-persistent-net.rules (because the device doesn't match the dynamically generated rule there) ** Changed in: ifupdown (Ubuntu) Status: Fix Released => Confirmed -- udev rule can fail to run ifdown, break reinserting device https://bugs.launchpad.net/bugs/130437 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
