Error on step "Create localhost binary cache path" if "become: true" is set on whole playbook

[phidah]

I have a playbook with become: true for the whole playbook.

I use the prometheus.prometheus.redis_exporter role as so:

- name: Install Prometheus Redis Exporter
      include_role:
        name: prometheus.prometheus.redis_exporter

I, however, get stuck at this step:

TASK [prometheus.prometheus._common : Create localhost binary cache path] ***************************************************************************

Even if I try wrapping it in a non-elevated block, it still tries to sudo:

- name: Install Prometheus Redis Exporter without elevated privileges
  block:
    - name: Install Prometheus Redis Exporter
      include_role:
        name: prometheus.prometheus.redis_exporter
  become: false

In #427 an issue causing errors (or an infinite sudo prompt), if "become: true" was set on the whole workbook was fixed. It seems that my issue is the same. Some changes were done in 6209b53 where the become: false statement on the task Create localhost binary cache path moved.

It seems that somehow the become: false set in the "Download binary ..." task of the install.yml file is not being respected.

Is this a bug?

Is there any reason why you need to apply become to the whole playbook?

When you apply the become to the playbook you are overwriting the individual become configuration of every task.

I know some other roles don't specify become for individual tasks but the roles in this collection are all designed where the tasks run only with elevated privileges where needed.
