[Nix-dev] Nix OS installation problems - Where's the hard drive?

[Joseph Joe]

Wout, your instructions worked.

So, for my purposes, changing that one line in nixpkgs and using the
release.nix file in that folder worked.

The pull request seems to have failed checks however.
https://github.com/NixOS/nixpkgs/pull/4587

Thanks for the help everyone.

Now, to finally spend time using NixOS!
