It’s not so much OCD as it is DISA STIG. The RHEL6 STIG rules explicitly state for specific services that if it’s not needed on a host it must be disabled/uninstalled. Granted I don’t need to do that for every possible service, but I do have to do it for specific services. What I may end up doing is have a general ‘base’ OS playbook for when I’m setting up host that only turns on stuff. And then have a separate STIG playbook that I run occasionally to ensure that only those needed services on a given host are actually enabled and other STIG-identified services are not.

It would be impossible to define all the things a server could not be.

I’m sure this can all be done a better way, but right now, I’m just not seeing it. Can anyone offer suggestions of what else to try here? I'm sure that there are many better ways... First, you can detect you OS programmatically and add it to the appropriate group... I start with a playbook that has this... --- # file: group.yml - hosts: all gather_facts: true tasks: - group_by: key={{ ansible_os_family }} - group_by: key={{ ansible_product_name.split()[0] }} This creates a group for each OS family (RedHat/Debian/AIX) but you can be more specific if you want, and one that lets me detect HP Proliant hardware (I have some tasks specifically for that...) Then I run some playbooks with generic tasks some of which have alternatives for different OSes. Equally I could split these into four roles, one for Generic tasks, and one for each of the OS variants... If the only difference between two tasks is some parameters (This file should be owned by group "sys" on this OS but "root" on that...) then I use variables for those differences and set variables for different groups in the group_vars directory. And I did this for *EVERY SERVICE* (xinetd, vsftpd, httpd, etc….) on my hosts. In short, if it didn’t have to be on, it had to be explicitly disabled. [If there’s a better form for these types of patterns, PLEASE let me know – it’s so verbose and ugly, especially duplicated for every service I have on my boxes.] Much better would be to have a list of services to disable and use with_items... - name: Ensure servers removed yum: name={{ item }} state=absent with_items: remove_server_list You can get fancier still, but this should be enough to get you moving along cleaner lines...
