Comment 33 for bug 1815101

FYI I stumbled on this problem after a system update (which broke production!) and collected data in a troubleshooting session and documented this here https://www.claudiokuenzler.com/blog/959/keepalived-virtual-ip-addresses-gone-lost-after-systemd-update. Once I found out the restart of systemd-networkd causes the keepalived vips to be gone, I finally came across this bug.
