While Puppet may get all the glory, Facter, the hard working information gathering library that can, seldom gets much exciting new functionality. However with the release of Facter 1.7 Puppetlabs have standardised and included a couple of useful facter enhancements that make it easier than ever to add custom facts to your puppet runs.
These two improvements come under the banner of ‘External Facts’. The first allows you to surface your own facts from a static file, either plain text key value pairs or a specific YAML / JSON format.
