On a Bionic/Stein cloud, after a network partition, we saw several units (glance, swift-proxy and cinder) fail to start haproxy, like so:

The Debian maintainer came up with the following patch for this:

  https://<email address hidden>/msg30477.html

Which was added to the 1.8.10-1 Debian upload and merged into upstream 1.8.13.
Unfortunately Bionic is on 1.8.8-1ubuntu0.4 and doesn't have this patch.

Please consider pulling this patch into an SRU for Bionic.
