TASK [dev-sec.os-hardening : remove deprecated or insecure packages | package-01 - package-09] *******************************************************************************************************************
[DEPRECATION WARNING]: Invoking "yum" only once while using a loop via squash_actions is deprecated. Instead of using a loop to supply multiple items and specifying `name: "{{ item }}"`, please use `name: ['{{
 os_security_packages_list }}']` and remove the loop. This feature will be removed in version 2.11. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
ok: [host1] => (item=[u'xinetd', u'inetd', u'ypserv', u'telnet-server', u'rsh-server', u'prelink'])
