# In Chef, when a resource is defined all its variables are evaluated during
# compile time and the execution of the resource takes place in converge phase.
# So if the value of a particular attribute is changed in converge
# (and not in compile) the resource will be executed with the old value.
# Example problem:
# Let's consider this situation where there are two steps involved in a recipe
# Step 1 is a Ruby block that changes a node attribute. Rubyblocks get executed
# in converge phase
# Step 2 is a Chef resource that makes use of the node attribute that was
