What I tend to do that scratches the distro-hopping itch is I keep an external drive with a bunch of virtual machines on it that I can spin up and tinker around with as needed, like little specimen jars lol. I think I have about 5-6 on the go at the moment. So like my actual computer runs Arch (btw), but I have VMs for NixOS, OpenSUSE, Mint and so on, as well as another one that’s as close to my main system as possible so if I want to try a weird experiment I can try it on there first to see what breaks. Just today I tried upgrading it to Plasma 6 to see what broke and the answer was everything lol.
I used to keep ones for Mac and Windows on the go too, but they tend to eat up a lot of drive space.
