Hi,

here is my site.yml:

---
- name: apply common configuration
  hosts: all
  remote_user: zgansible
  become: "yes"
  tasks:
  - name: get package facts
    package_facts:
      manager: "auto"
  - import_role:
      name: mlocate
    when: ansible_facts.packages["mlocate"] is defined

That one doesn't work:
fatal: [emptysid86]: FAILED! => {"msg": 
  "The conditional check 'ansible_facts.packages[\"mlocate\"]
     is defined' failed.
   The error was: error while evaluating conditional
     (ansible_facts.packages[\"mlocate\"] is defined):
     'dict object' has no attribute 'packages'
   The error appears to have been in 
'/home/mh/git/zgdebansible/roles/mlocate/tasks/main.yml':
   line 2, column 3, but may
   be elsewhere in the file depending on the exact syntax problem.
   The offending line appears to be:- name:create symlinks for mlocate
                                      ^ here
"}

The alternative, writing the when clause into all tasks in the role,
clutters up the roles and makes them unportable. Also, I need to have
all my roles depend on package_facts, which for some weird reason causes
the package_facts role to be re-executed over and over and over again
which takes ages.

How would I make the ansible_facts.packages dictionary universally
availabe while only collecting the list of installed packages once?

Greetings
Marc
