Bernardo Meurer 6e849e3b0a 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. Fixes: #4598		2021-03-04 18:54:45 -08:00
