puppet-module-puppetlabs-host-core 1.0.3-2 (amd64 binary) in ubuntu lunar

 Puppet lets you centrally manage every important aspect of your system using a
 cross-platform specification language that manages all the separate elements
 normally aggregated in different files, like users, cron jobs, and hosts,
 along with obviously discrete elements like packages, services, and files.
 .
 The host_core module is used to manage host entries in a hosts file. For most
 systems, the hosts file is located in /etc/hosts.
