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

[Alexander Zubkov]

There was a typo, I think. It should be:
/nix/store/*/nixos/nixos/release.nix
I also usually find this directory using ~/.nix-defepr
Also, I think that using nix-build with this release.nix is not enough, 
you should copy it and make there some changes to embed your kernel 
configuration. Because I think it does not use your system 
configuration.nix. But thus is my assumption and I'm not 100% sure.
