Is there an easy way to create a Linux distribution for fun?

For simpler guides, I’d recommend looking up YouTube tutorials; they can guide you through creating the basic structure you need without requiring extensive knowledge. I recently found a pretty straightforward video that’s great for beginners!

Unfortunately, there's no one-stop solution for creating a full distribution without some coding. Most distros started with someone piecing together the kernel and various components, so it's a bit of a learning curve. However, you could create themes and introduce modifications using platforms like Pling.com to get a custom Ubuntu flavor, but it won’t give you a fully unique distro without more effort.

You might want to check out Kiwi-NG. It's a tool that helps you deploy customized versions of a Linux distro. It originally started with OpenSUSE but supports other distros as well. It could simplify some of the process for you!
