…eation Preserving ArgvZero is supported from MacOS 14 Sonoma forward, which is the current minimum supported version of nixpkgs. See https://developer.apple.com/documentation/virtualization/running-intel-binaries-in-linux-vms-with-rosetta#Mount-the-Shared-Directory-and-Register-Rosetta The necessity of this fix came up with python virtual environments, because python uses the path of the executable (argv zero) to determine if it should load a virtual environment or not. In the past this was overriden with NIX_PYTHONEXECUTABLE, NIX_PYTHONPATH and NIX_PYTHONPREFIX, but we stopped doing that for the python interpreter so it works more like a normal python interpreter in nix. Without those variables, in the rosetta emulated case, python was no longer able to determine where it was called from, and thus could not correctly activate virtual environments in that case. (cherry picked from commit f5eb10b)
