/dev/fd/3: Permission denied in build environment

[bemyak]

Hi!

I'm trying to build a Rust package inside a nix-on-droid environment, but the build fails on the installation phase:

Running phase: installPhase
@nix { "action": "setPhase", "phase": "installPhase" }
searching for bins/libs to install from cargo build log at cargoBuildLog3y5q.json
installing /tmp/nix-build-zola-new-0.1.6.drv-0/source/target/release/zola-new
searching for bins/libs complete
stripping references to cargoVendorDir from:
tee: /dev/fd/3: Permission denied

(the origin is here I believe)

Seems like there's something wrong with the permissions of /dev/fd/3. I can write in it in:

• adb shell
• termux shell
• nix-on-droid shell

… but not in the build environment.

Any ideas how to fix this?
