Hey guys,
I'm pretty new to Nix and NixOS and one of the reasons I installed it is because I know there's some way to install the KDE 6 Beta before the official stable release. I wanted to use the kde2nix overlay, but appearantely KDE 6 has been merged into the official nixpkgs repository. How do I switch from Plasma 5 to 6? I'm already on the unstable channel if that matters.
But kde2nix is archived on GitHub? And it doesn't have any instructions in the README, it just says "Merging into Nixpkgs: NixOS/nixpkgs#286522". How do I actually use it, what do I have to put in my configuration.nix file?
