Hi,

I have CentOS Atomic Host ([http://www.projectatomic.io/](http://www.projectatomic.io/)).

When I execute:

ansible -m setup my\_atomic\_os

I have:

“ansible\_os\_family”: “RedHat”

I see nowhere that this is a Atomic version of RedHat / CentOS (on Atomic host I can’t install package…).

How can I detect this with facts mechanism?

I need to create an Ansible issue on GitHub about this feature request?

Best regards,  
Stéphane

Start with: how would I tell the host is an Atomic host without Ansible?

Then you can combine a command: with a register:clause,  
and run set\_fact with a when: .

For the effort, I'd just add a custom fact. But without knowing how to tell,  
that's tricky 🙂

Thanks

It is possible to override ansible\_os\_family fact?

I try that:

[all]  
[atomic-test-node.example.com](http://atomic-test-node.example.com) ansible\_user=root ansible\_os\_family=atomic

But it don’t work ☹

This don't override default Ansible facts.
