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

[Joseph Joe]

David, that modification worked and set the hard drive parameter. Thanks!

I now would like to create an image file from the configuration.

I issued the command:
$ export NIX_PATH=$NIXREPOS

But, the command:
$ nix-build -A iso_graphical.x86_64-linux $NIXREPOS/nixos/release.nix

returns with the error:

error: getting status of `/nixos/release.nix': No such file or directory


Wout, I do not have a directory /nix/store/*/nixpkgs for some reason.
I am pretty sure I have nix pkgs installed since it comes with Nix OS.

my current path in the non root account is
/nix/store/6kkqnidx9k0j137zs2mwvd2f8j7fzlxp-kde-workspace-4.11.6/bin:/home/joej/bin:/var/setuid-wrappers:/home/joej/.nix-profile/bin:/home/joej/.nix-profile/sbin:/home/joej/.nix-profile/lib/kde4/libexec:/nix/var/nix/profiles/default/bin:/nix/var/nix/profiles/default/sbin:/nix/var/nix/profiles/default/lib/kde4/libexec:/run/current-system/sw/bin:/run/current-system/sw/sbin:/run/current-system/sw/lib/kde4/libexec

In the root account, the path is
/root/bin:/var/setuid-wrappers:/root/.nix-profile/bin:/root/.nix-profile/sbin:/root/.nix-profile/lib/kde4/libexec:/nix/var/nix/profiles/default/bin:/nix/var/nix/profiles/default/sbin:/nix/var/nix/profiles/default/lib/kde4/libexec:/run/current-system/sw/bin:/run/current-system/sw/sbin:/run/current-system/sw/lib/kde4/libexec
