nix-dram as default nix binary isn't worth the
maintenance work anymore, CI builds started
failing because of it:
https://ci.b12f.io/pub-solar/os/533/1/2
Automatic builds still happen each night and can be
checked in our fork of nix-dram:
https://github.com/pub-solar/nix-dram/actions
Users of nix-dram can continue to use it via devshells
or nix run github:dramforever/nix-dram -- --version
