As title says. Obviously I could setup different virtual machines or spend the time and install all the DEs in one VM if it is even possible without breaking the OS. I'm wondering if there is an already made iso or something that installs all the maintained DEs for trying.
wow. I gotta check out nixos. That is incredible. Do you happen to know if fedora silverbue or any of the other immutable distros do this, or is this something specific to nixos?
Guix might also be able to do this but I don't think the others can.
This relies on NixOS' declarative configuration which Silverbluae and the like do not have; they are configured imperatively.
I did some research yesterday and it looks like silver blue has some rebase command that does something similar. Universal Blue is using that to make it easy to switch between DEs, netting a very similar result!
