From 6e849e3b0a6eb46e6dc65cbd091cc829eab09a5f Mon Sep 17 00:00:00 2001 From: Bernardo Meurer Date: Wed, 3 Mar 2021 14:46:15 -0800 Subject: nix-build: set execfail When starting a nix-shell with `-i` it was previously possible for it to silently fail in the scenario where the specified interpreter didn't exist. This happened due to the `exec` call masking the issue. With this change we enable `execfail`, which causes the script using `nix-shell` as interpreter to correctly exit with code 127.
