[Nix-dev] cabal2nix, nix-shell and persistence trick

[Ruben Astudillo]

Hi all.

When using `cabal2nix --shell . > shell.nix` and the persistent
environment trick[1] as shown in the wiki, the resulting environment
correspond to the actual one. Instead if I just launch `nix-shell` with
the output of cabal2nix --shell I get the correct setup.

Anybody with experience on this?. How do you set-up persistent
environment with cabal2nix?
