Solid playbook, but why not use `apt` for Debian-based systems?

I think the playbook structure looks right, but I'm a bit confused about how to handle the `hosts` declaration for the Development Tools installation. Should it be separate?

I believe we should definitely include the `exclude` option for the kernel packages when updating, but I wonder if there are other packages we should exclude as well.

I practiced a similar question where we had to install multiple packages, but I can't recall if we used `vars` correctly in this context.

I think I remember that we need to use the `yum` module for installing packages, but I'm not entirely sure about the syntax for the `state` parameter.

The playbook structure looks good. I like how they're using variables for the package names. That'll make it easy to update in the future.

Okay, I see we need to install packages on different host groups. The tasks look clear, but I'm a bit unsure about the "state: latest" part. Does that mean it will update all the packages?

Hmm, not sure about the "hosts" line. Do we need to specify the host groups explicitly or can we just use "all"?

This seems like a pretty straightforward question. The users need a single screen in a model-driven app, so I think the answer is to modify the site map. That should give me the functionality I need to configure the app correctly.
