The sandbox was (probably) enabled due to the .stack/shell.nix files: it made use of buildStackProject, which requires to run outside of the sandbox for some reason ( https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/generic-stack-builder.nix#L25 ). Now that this file is not used anymore, we can reenable the sandbox.
It should help fix in particular this recent issue we’re facing in the CI: https://github.com/jfischoff/tmp-postgres/issues/251
