Describe the bug

I found that there is a flake.nix and flake.lock in the repo
I tried to install warp with home-manager, and it was failed with:
error: the package 'warp' does not contain this feature: nld_improvements

To reproduce

add warp to flake.nix:

    nixpkgs = {
      url = "github:NixOS/nixpkgs/nixos-unstable";
      # url = "github:NixOS/nixpkgs/nixos-unstable-small";
    };
    crane = {
      url = "git+https://github.com/ipetkov/crane";
    };
    rust-overlay = {
      url = "git+https://github.com/oxalica/rust-overlay";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    warp = {
      url = "git+https://github.com/warpdotdev/warp";
      inputs.crane.follows = "crane";
      inputs.nixpkgs.follows = "nixpkgs";
      inputs.rust-overlay.follows = "rust-overlay";
    };

add the package to home.packages:

inputs.warp.packages.${pkgs.stdenv.hostPlatform.system}.warp-terminal-experimental

then try home-manager switch --flake .

Expected behavior

warp terminal can be used

Does this block you from using Warp daily?

No

Is this an issue only in Warp?

Yes, I confirmed that this only happens in Warp, not other terminals.

Here's what I found while triaging this issue:

This looks like a stale feature flag in the experimental Nix flake rather than a local Home Manager configuration issue. #9296 is related background for the flake support, but I did not find enough matching duplicate reports to mark this as a duplicate.

Maintainer details

I concluded that the experimental Nix flake package currently fails because it still enables the removed Cargo feature nld_improvements..

Triage summary

This appears to be a reproducible Linux/Nix packaging bug in the experimental flake package. The provided build log shows the Nix package invoking Cargo with --features=release_bundle,gui,nld_improvements, and Cargo fails because the warp package no longer declares nld_improvements.

Likely root cause

The repo's Nix package still includes nld_improvements in flake.nix under buildFeatures, while the current app/Cargo.toml feature list no longer defines that feature after the NLD feature cleanup. Removing or replacing that stale feature in the flake build feature list should unblock this stage of the Nix build.

Duplicate check

I scanned all open non-PR issues plus recently closed issues. #9296 is related because it requested first-party Nix flake support and was closed recently, but I did not find two existing issues with the same nld_improvements Cargo feature failure, so this should not be marked as a duplicate.

This is my automated analysis and may be incorrect. A maintainer will verify the details.
