Description
Hi.
TL;DR: See Nix installer issue that seems to happen only on Rust coreutils (and not GNU's).
I've been trying to install several versions of Nix with its installer on Ubuntu 25.10 dailys, which come with Rust-based coreutils. And I have experienced some permission errors that shouldn't happen. Actually, removing Rust coreutils and using GNU Coreutils allows the installation to complete successfully.
I don't know exactly where the problem is, but I filed a bug with the Nix installer where there's additional details about the error and versions affected.

Research direction
Start with the linked Nix installer issue #14101 and compare the Rust-based coreutils with GNU coreutils on Ubuntu 25.10 dailys. Reproduce the installation failure, identify the affected utility and permission behavior, then add a regression test showing that the installer completes successfully.
