i think is not necessary a installation test

I think we'd like a separate profile for this, rather than inject it on all desktop profiles (even tho, I agree, this would raise the minimum level security of desktops).

But consider users selecting the server profile. We'd want to increase security there too.

So ideally, what we would like is a separate "security" profile - and allow multi-select on profiles so that people can select:

[x] Desktop
[x] Security
[ ] Server

(Just as a crude example)

I think this is too opinionated. There are multiple competing ways to set this up, like ufw for instance. Firewalls could be a post-installation configuration item for the end user.

I agree, for now I'll close this in the current form it's implemented.
