Hi Xie,
We solved the problems with the yum repos an other way.
Maybe a way to solve this is by using when with your task. You pass a
variable with your role and check that with the when clause of your task.
If you for example define your role the following way:
- { role: foo_role, execute: false }
And then in your task you say:
- command: /bin/something
when: execute
