alt Hacker NewsThe privileged path is already there. `/usr/bin/env` is no different from `/bin/bash`, `/bin/sh`, or any other ELF artifact at a known place. The argument is made, the argument is spurious. It is made in the other direction regarding the driver run path, just as religious, opposite ruling from purity court. No one even knows why, the trail goes cold in a mysterious 2012 commit about Mesa, it's literally a performance to bring the plane cargo back. Receipts for claim: #141803.
Disagreeing with you doesn't make something a rant. If it's not clear how deep my Nix expertise is I will demonstrate it to any level you like: I'm just as entitled to an opinion as you are and I would appreciate it if the nixpkgs community was a little less rude to anyone who disagrees with some dogma no matter their knowledge. The nixpkgs community is not regarded as healthy or friendly after an internecine faction war that split three ways twice, producing four implementations none of which work, and if that reputation is ever going to mend, it will be because less than every Nix person has precisely zero chill the nanosecond anyone disagrees with them about anything.
It's no different other than it's a layer of indirection which allows bash to change in a way that would not be possible if scripts directly referenced /bin/bash or /usr/bin/bash. The only thing you can't change is the /usr/bin/env binary itself but that's not something that changes very much if at all. On my nix box, bash is at /run/current-system/sw/bin/bash and "current-system" is a symlink to a particular build in /nix/store. So /usr/bin/env is creating a layer of indirection so if I rebuild the system, the previous version can be kept around and I can roll back instantly at the boot menu and it will roll everything back to a consistent package set. Now as I say, you could achieve this in other ways eg fs snapshots etc. But to say that the change doesn't give you anything is just very obviously wrong.
And you don't need to worry- it's perfectly obvious how deep your Nix expertise is.
