Comment 7 for bug 1703618

So, I ran both repo setups again to test for which architecture repos are built:

- With a repo_container only on the x86 node I do only get the repos for x86 arch
  - During TASK [Prepare group of master repo servers] the only changed item is:
    changed: [localhost] => (item=repo_servers_16.04_x86_64)
- With a repo_container on each node repos for both architecture are built
  - During TASK [Prepare group of master repo servers] two items are changed as expected:
    changed: [localhost] => (item=repo_servers_16.04_armv7l)
    changed: [localhost] => (item=repo_servers_16.04_x86_64)
  - What confused me yesterday was that this process is executed not in parallel but in sequence for each arch.
  - I was not yet able to test if the repos are accessed correctly
