[Tony Breeds]

Current ironic-conductor can fail to deploy nodes with an error like:

On a CentOS-7 this comes from systemd, on RHEL-8 (beta) this comes from systemd-udev and on ubuntu 16/18 it comes from udev.

This is a recent requirement from ironic and has been backported to queens:

Thanks for raising this Tony. It appears that RDO includes the dependency: https://cbs.centos.org/koji/rpminfo?rpmID=160048, so this will just apply for source centos/rhel images and all debian/ubuntu images.
