module ChefHelpers
# This is for "introspection" helpers in the sense that we are inspecting the
# actual server or image under management to determine running state (duck-typing the system).
# The helpers here may use the node object state from ohai, but typically not the big 5: platform,
# platform_family, platform_version, arch, os. The helpers here should infer somewhat
# higher level facts about the system.
