Variables are lazily evaluated and computed per host. The issues with
set_fact are that the evaluation is happening before setting the
variable as ansible evaluates the expression to pass it to the task:
so
vars:
varname: "{{expression}}" # this is lazy
- set_facts: varname={{expression}} #var is set to result of
'expression' as it is evaluated for the task.
I hope that clarifies the issue.
