if you don't have 8gb memory, but forget to disable-system-checks, it will put your system in a state of unfixable without editing the script itself
Created from redmine issue http://projects.theforeman.org/issues/20430
Upstream bug assigned to email@example.com
Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/20430 has been resolved.
The katello-change-hostname.rb installer script has been updated and added the "disable-system-checks" line. This was verified both on a system that has 8gb and a system that has greater than 8gb.
# grep "disable-system-checks" /usr/share/katello/hostname-change.rb
installer << " --disable-system-checks" if disable_system_check_option?
Verified on 6.5.0 snap 7.0
