[Regression Potential] * Even in the default config (just enabling it to run) this doesn't work. Hence the risk should be next to none. I can think of setups that "are meant to work" , but so far "didn't start" now properly would start. For example if someone configured the service but ignored that it failed to start. I hope and expect that this is a rather unimportant risk, it actually is the fix we are intending to make. [Other Info] * TBH it is in main for a dependency from keepalive but I wonder how much that could be a sugegsts instead. But that is for the future. --- The launch script for ipvsadm has a bug that prevents LVS from start in synchronization mode. How to reproduce. 1. Install ipvsadm on ubuntu server 16.04 and modify /etc/default/ipvsadm to lauch LVS in master mode (or backup): AUTO="true" DAEMON="master" IFACE="eno1" SYNCID="0" 2. Start "ipvsadm" service and check systemd unit log: # systemctl start ipvsadm # journalctl -u ipvsadm What you expected to happen The log output without error: May 22 12:41:46 xxxxxxxxxxx systemd[1]: Starting LSB: ipvsadm daemon... May 22 12:41:46 xxxxxxxxxxx ipvsadm[4619]: * Clearing the current IPVS table... May 22 12:41:46 xxxxxxxxxxx ipvsadm[4619]: ...done.

As you can see in log output, there is an message: "Try `/sbin/ipvsadm -h' or '/sbin/ipvsadm --help' for more information". This message relates to bug in script /etc/init.d/ipvsadm.
