puppetlabs-stdlib/lib/facter/puppet_vardir.rb

# This facter fact returns the value of the Puppet vardir setting for the node
# running puppet or puppet agent.  The intent is to enable Puppet modules to
# automatically have insight into a place where they can place variable data,
# regardless of the node's platform.
#
# The value should be directly usable in a File resource path attribute.
