I have a 1TB harddrive on my desktop computer that isn't doing much of anything, so I'd like to dual-boot something "interesting". Suggestions are greatly appreciated, so let me know what y'all find intriguing/interesting/frustrating/innovative.
The logo is just for attention, but EFF is a great cause that we should all support.
I haven't had an opportunity to test it myself yet, but I've heard very good things about NixOS. The basic premise is that all of your system state, every config file in /etc, every package you have installed, everything, is defined by a single configuration file called configuration.nix. If you back up just your home directory and that file, you can plonk it into a brand new copy of NixOS, run a single command, and have it redownload and re-set-up everything else exactly how you left it.
Speaking of, how is NixOS for gaming? I remember trying it a while ago but not being able to get the Nvidia drivers working. I've since switched to a machine with AMD graphics though.
Steam with Proton works OOTB for me if you enable the option in the system config.
It's even better with flakes. I barely touched the surface but I just run nix run . boot all and rebuilds all systems with the same build / versions. This the run . Part executes a python script that loops through each host and runs nixos-rebuild. I run my k3s cluster with it.
