Hello.  
how to update the local vars, after receiving the input parameter  
example:

roles/new/vars/main.yaml  
list:

- name: service1  
pckg: namepckg  
version: trunk

- name: service2  
pckg: namepckg  
version: trunk

run playbook start.yaml

- hosts: somehost  
remote\_user: ansible  
connection: ssh  
become: yes  
gather\_facts: nj  
vars:  
revision: “tags-2.6”  
roles:
- new

I want to update vars pckg for service2 and/or service1 (use with\_subelements) to a value revision

should get

- name: service1  
pckg: namepckg  
version: tags-2.6

- name: service2  
pckg: namepckg  
version: tags-2.6

how to do it?
