Ruby

A systems integration framework, built to bring the benefits of configuration management to your entire infrastructure.

Chef::Node#run_context=

RunContext will set itself as run_context via this setter when
initialized. This is needed so DSL::IncludeAttribute (in particular,
#include_recipe) can access the run_context to determine if an attributes
file has been seen yet.

TODO: This is a pretty ugly way to solve that problem.
