Puppet Enterprise might be a bit more popular than Uyuni. We know about 1 link to it since March 2021 and only 1 link to Uyuni. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Uyuni (https://uyuni-project.org), SUSE fork of Spacewalk and Upstream of SUSE Manager. But CentOS 6 will be a problem because it's EOL. I suggest to setup Uyuni, attach all Systems which are not yet EOL and take care about the EOL Systems via Ansible or whatever else you prefer and as soon they are running an up to date OS attach them to Uyuni as well.

Now that the system requirements have been verified we need to download the Puppet Enterprise installer. To download the installer, go to the Puppet website to access the free 10 node trial (https://puppet.com/try-puppet/puppet-enterprise). - Source: dev.to / over 2 years ago
