[Nix-dev] Nix fatal error

[Pjotr Prins]

Ah, it is easier than I thought. I could rebuild the coreutils with
the patch applied using an older version of nix in the tree:

  /nix/store/gn7d1rl6i6sm36lxdwa8xyy9bg61jp1y-nix-0.12pre12409/bin/nix-env -f . coreutils

Neat.

See, sometimes it just helps to post a problem.

Pj.
