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...

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.
Here a difference how script should be updated to get it work:

[Impact]
* the init script has an argument twice, which makes the service fail to
start
* Without the fix the service is rather unusable as it can't be started
[Test Case]
* Needs a VM (no container)
$ sudo apt install ipvsadm
$ echo 'AUTO="true"' | sudo tee -a /etc/default/ipvsadm
$ echo 'DAEMON="master"' | sudo tee -a /etc/default/ipvsadm
$ sudo systemctl restart ipvsadm
$ systemctl status ipvsadm
With the bug this will show the sevrice failing
[...]
Try `/sbin/ipvsadm -h' or '/sbin/ipvsadm --help' for more information.
...fail!
[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.
