Looks like backports would be needed for cosmic-updates, bionic-updates,
and (presumably) xenial-updates.

Title:
  [SRU] Keepalived update from 1.2.19 to 1.2.24 breaks support for
  /dev/tcp health check

Status in keepalived package in Ubuntu:
  Fix Released
Status in keepalived source package in Xenial:
  Triaged
Status in keepalived source package in Bionic:
  Triaged
Status in keepalived source package in Cosmic:

Bug description:
  Previous configuration that works fine:

  vrrp_script chk_trigger_port {
      script "</dev/tcp/127.0.0.1/53"
      interval 5
      weight 30
  }

  This syntax is documented all over, and worked properly in 1.2.19, but
  update to 1.2.24 package broke it.

  Resulting symptom is that keepalived will continuously fail with a
  FATAL error and respawn, and will not ever come online fully.

  Tracing the service, it is getting a no such file or directory on the
  /dev/tcp script. I have not looked at the code changes, but I suspect
  there was some optimization to not use bash, or change in how the
  script is executed - breaking support for that syntax.

  I was able to work around with:

      script "/bin/bash -c '</dev/tcp/127.0.0.1/53'"

  but that still leaves all of the incorrect documentation.

  Looks like it may have already been corrected upstream - please
  backport this fix to ubuntu 16.04 package train please:
