Hi all, With SystemD, how can I make certain service dependent on certain network interfaces being up? For example, I have an 802.1ad bond interface I need to wait on for being up (this interface has no ip address assigned, it is used to capture networks packets with a tcpdump?s script). Every time this service fails because bond interface is not up. I have configured the service as:

Sorry for replying to this ancient thread. There was some remaining issue that I don't think the initial net_failover patch got addressed cleanly, see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1815268 The renaming of 'eth0' to 'ens4' fails because the udev userspace was not specifically writtten for such kernel automatic enslavement. Specifically, if it is a bond
