 ### Why not just use nixOS?
 
 Ubuntu is the most popular mainstream Linux distribution. It's available out-of-the-box from major manufacturers. It's learning curve is low, it's polished, it's stable, and if you hit problems, you'll easily find others online with the same issue. That doesn't mean it's The Best.

And some, like nixOS, have been specifically designed for some of the same preconfiguration ideas that we're exploring here. But it just doesn't matter. This is a project for tailoring Ubuntu (and derivatives built on it and similar base elements).
