Description

the code should only added the extra line for the hostname if there isn't already a line for the hostname in /etc/hosts. It was a failsafe that was added since the step was often skipped/forgotten in the docs, and multiple services (particularly rabbitmq) are quite picky about the name being in /etc/hosts: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html-single/director_installation_and_usage/#sect-Setting_the_Hostname_for_the_System That being said, I didn't realize that technically that syntax with the same IP on multiple lines is invalid. You should be able to workaround the issue if you set it yourself though. Yes, I completely understand the reasoning behind adding the setting to undercloud.conf. Just wanted to bug report it so it does eventually get fixed.
The manpage for /etc/hosts reads:
This manual page describes the format of the /etc/hosts file. This
file is a simple text file that associates IP addresses with
hostnames, one line per IP address. For each host a single line
should be present with the following information:
IP_address canonical_hostname [aliases...]
