Think of it as multiple user lands on one distro. So, why?
What if I really love the stability and familiarity of Debian Stable but applications that are either ancient versions or totally missing in Debian? Well, I could use Distrobox on Debian to get access to the Arch Linux repositories ( the largest collection of Linux software anywhere ).
What if I do not want to install huge Flatpaks for the above and prefer more traditional package management and more timely updates?
What if I want to setup a dev or test environment, want to be able to make a mess and remove it later, not also want access to my other tools and files from that environment?
What if i want to experience other package managers and userlands without having to lose my existing system only to discover I do not like it?
What if I want to build software for a specific disto and want to access files and tools on my main distribution to do so?
I am sure there are many, many more reasons.
Anyway, it is just one way to do things with pros and cons like anything else. Personally, I really like it.
One use case I had was I wanted to use STM32 Cube IDE, but it has a dependency on python 2.7 I think it was. I had some trouble installing it on my main OS, but I was able to get it to work on Ubuntu 22.04 running in a Distrobox.
Why would you need multiple distros at the same time?
