I don't seem to be able to reproduce this. On my target box I have: -bash-4.1$ nix-channel --list nixpkgs http://nixos.org/channels/nixpkgs-unstable -bash-4.1$ NIX_STORE_DIR=/u/c/mk440/localsoftware/nix/store nix-instantiate --readonly-mode '<nixpkgs>' -A hello warning: you did not specify `--add-root'; the result might be removed by the garbage collector /u/c/mk440/localsoftware/nix/store/bxfj2spplwca162s2yklrxngjj4cb4r7-hello-2.9.drv -bash-4.1$ uname -a Linux lcpu1.bath.ac.uk 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 23:32:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux And on the box I wish to compile on: [shana@lenalee:~]$ nix-channel --list nixpkgs-local http://nixos.org/channels/nixpkgs-unstable nixos http://nixos.org/channels/nixos-unstable [shana@lenalee:~]$ NIX_PATH="nixpkgs-local=/home/shana/.nix-defexpr/channels/nixpkgs-local" NIX_STORE_DIR=/u/c/mk440/localsoftware/nix/store nix-instantiate --readonly-mode '<nixpkgs-local>' -A hello warning: you did not specify `--add-root'; the result might be removed by the garbage collector /u/c/mk440/localsoftware/nix/store/1h8sxxyp8jn832l0fn3d1wf43jcbcf4b-hello-2.9.drv [shana@lenalee:~]$ uname -a Linux lenalee 3.12.21 #1-NixOS SMP Thu Jan 1 00:00:01 UTC 1970 x86_64 GNU/Linux So I end up with two different hashes. What could I be overlooking? If it's about software outside of the nix store then I don't think it's feasible to get that to match up. > On Fri, Jun 13, 2014 at 7:56 PM, Mateusz Kowalczyk <[email protected]> > wrote: > >> On 06/13/2014 02:33 PM, Vladimír Čunát wrote: >>> On 06/13/2014 02:19 PM, Andreas Herrmann wrote: >>>> Given a case where you can't get the admin to give you `/nix`, and where >>>> you have space/compute constraints on the target, would it be possible >>>> to create the full nix install on your own local machine in the correct >>>> paths, and then just copy it to the target?
