I’m using Documenter on NixOS. When I run `julia --project make.jl`, I get the following error:

```julia-auto
┌ Warning: Unable to determine HTML(edit_link = ...) from remote HEAD branch, defaulting to "master".
│ Calling `git remote` failed with an exception. Set JULIA_DEBUG=Documenter to see the error.
│ Unless this is due to a configuration error, the relevant variable should be set explicitly.

│ IOError: could not spawn setenv(`/home/laikq/.julia/artifacts/8cb25db9a73519e871cc50d6915f8ab2770096f3/bin/git remote show origin`

```

Obviously, calling `git` fails. This comes as no surprise, since `ldd ~/.julia/artifacts/8cb25db9a73519e871cc50d6915f8ab2770096f3/bin/git` also shows:

```julia-auto

```

I’m not sure what’s the best way to proceed to get Documenter to use git normally. I know that I can also disable git, but this doesn’t work (or I don’t know how to make it work) for the function `doctest`. Maybe [nix-alien](https://github.com/thiagokokada/nix-alien) or [nix-ld](https://github.com/Mic92/nix-ld) are part of the solution, or [artifact overrides](https://pkgdocs.julialang.org/v1/artifacts/#Overriding-artifact-locations).

An ad-hoc solution is adding this to `Overrides.toml`:

```julia
[f8c6e375-362e-5223-8a59-34ff63f689eb]
Git = "/run/current-system/sw"

```

where the UUID is of `Git_jll`.

Hm. It would be nice to have a per-project `Overrides.toml` such that I can use a version of git as specified in `flake.lock`.
