It doens't fail without the patch. Could I ask what issue the
build-sandbox-paths introduce for you? Also it would be helpful
if you
provide terminal output with an error you occurred.
Ah, sorry I didn't see that there where system tests.
This is how I ran into the issue (nixpkgs/ folder is a checkout of
the nixpkgs repo).
```

The build succeeds if I do following:

--option build-sandbox-paths

Note that I need to use sudo as otherwise Nix would simply ignore
my request to override system configurations. And I had to run
`nix-build -A busybox` to make sure busybox was in the /nix/store.
The build-sandbox-paths I manually supplied seem to be the
defaults (as stated in documentation linked in John Soo's mail),
so I assumed that just removing the build-sandbox-path setting
from the nix.conf would solve the issue. I was a bit sloppy with
testing it completely...
This might be an upstream issue with how OCaml is built in Nix. I
think Nix builders should use ${stdenv.shell} instead of /bin/sh
(https://github.com/NixOS/nixpkgs/issues/183). But maybe good if
we can fix it in the Guix nix-service as well.
