In which module sub-directory should custom facts be placed to allow for synchronization using plugin sync?

Custom facts in Puppet are a way to extend the default set of facts provided by Facter, which Puppet uses to gather information about the system it is managing. To ensure that these custom facts can be synchronized across agents, they need to be placed in the correct directory structure specified by Puppet.

The lib/facter sub-directory is the appropriate location for custom facts intended for synchronization via plugin sync. This directory is designated for loading custom facts by Facter, which allows Puppet agents to retrieve and use these facts during their runs. When you place your custom facts here, they become accessible to all nodes that are connected to the Puppet master, ensuring consistency and allowing you to leverage the specialized information within your Puppet manifests.

Setting up the directory in this way takes full advantage of Puppet’s built-in mechanisms for fact gathering and data synchronization, making it crucial to adhere to this structure for proper functionality.
