emily	uh, what does GHC want an `xattr(1)` for, anyway?	14:27:04
sterni	https://gitlab.haskell.org/ghc/ghc/-/commit/bf65a7c388b	14:41:54
sterni	I never checked whether it is actually necessary, Randy set XATTR=/does-not-exist for some bindists. I just packaged the darwin one when GHC started failing because it started executing /usr/bin/xattr	14:42:43
sterni	emily: ah it used to be a literal fork of the python one (i.e. apple distributed the original (?) tarball and an ed(1) script) http://github.com/nixos/nixpkgs/commit/283d622397539f196416657da9dc804a4ca89846	14:48:17
sterni	I guess now that that has changed, we it is better to use the C one	14:48:29
emily	the Nix store can't contain `xattr`s	14:48:50
emily	I believe it strips them automatically	14:48:55
emily	so most likely you do not need to give it anything	14:49:01
sterni	but on write or on fixup	14:49:14
sterni	though I guess that doesn't matter	14:49:33
emily	https://github.com/NixOS/nix/commit/d798349ede3d6eb6e92a2e4f95f6b2179407ceb9	14:49:35
emily	uhh, `#if __linux__` :)	14:49:44
