Pulp

roles/pulp_common/tasks/main.yml executes command systemctl show-environment, which fails on a freshly installed CentOS 7.7 or 7.9 box.

fatal: [localhost]: FAILED! => {"changed": false, "cmd": "set -o pipefail\nsystemctl show-environment | grep -E '^PATH=' | sed 's/PATH=//g'\n", "delta": "0:00:00.009917", "end": "2021-02-01 11:35:20.328111", "msg": "non-zero return code", "rc": 1, "start": "2021-02-01 11:35:20.318194", "stderr": "Failed to get environment: Operation not permitted", "stderr_lines": ["Failed to get environment: Operation not permitted"], "stdout": "", "stdout_lines": []}

Adding become: true to this step fixes the issue,
