NixOS / Nixpkgs§

  • Nixpkgs Committer. Commit nomination/grant discussion

    I’ve worked with @LunNova on finally enabling PIE by default, CMake 4 fixes, and LLVM packaging changes relating to ROCm. I’ve found her to be highly skilled, easy to collaborate with, good at diving into unfamiliar issues across diverse areas quickly, and to have good taste for maintainable solutions. I strongly endorse her for commit access. ~ emilazy, nixpkgs core team member

    I nominate @LunNova for commit access. Luna is currently the most active maintainer on the ROCm (compute on AMD GPUs) package set which, since earlier this month, gets redistributed via cache.nixos.org! I have found her to be very capable when dealing with the enormous size of these packages and in her communication with upstream. Other notable contributions are the PIE enablement on packages built with GCC and the Go compiler. Luna has 94 merged PRs and close to 300 reviewed PRs. She started contributing in 2022, but really ramped up her contributions in 2025. I am confident that nixpkgs will benefit from granting LunNova commit privileges. I enjoy interacting with her! ~ mweinelt, nixos infra

  • De facto ROCm team lead. Driven all major version bumps after 6.0.2 (which was handled by mschwaig.)

ROCm packaging§

De facto lead for ROCm package set in Nixpkgs.

Major version bumps:

  • #367695 — rocmPackages: 6.0.2 -> 6.3.3
  • #427944 — rocmPackages: 6.3.3 -> 6.4.3

  • #436500 — python3Packages.triton: always support ROCm
  • #454399 — onnxruntime: add ROCm support

  • #457885 — whisper: set knownVulnerabilities due to dated vendored libraries

Security hardening: PIE by default§

Led the initiative to enable Position Independent Executables by default for GCC in nixpkgs, improving ASLR coverage across the distribution. Attempted and reverted similar effort for Go due to time constraints near release window.

  • #439314 — gcc: build with --enable-default-pie
  • #442510 — {cc-wrapper,bintools-wrapper}: drop pie hardening flag
  • #442965 — go: build PIE by default
  • #449771 — treewide: remove usages of obsolete pie hardening flag
  • #452791 — gcc: disable enableDefaultPie when !hasSharedLibraries
  • #461615 — go: revert default PIE changes

Nix (package manager)§

  • NixOS/nix#15417 — libstore: handle root path in RemoteFSAccessor::maybeLstat. Fixed nix build --store ssh-ng:// crashing with "path '/nix/store/' is not in the Nix store" — a regression since nix 2.29 (fixes NixOS/nix#15418)

CMake 4 transition§

Compat fixes across many packages for the CMake 4 transition in nixpkgs staging. Part of wider effort with many people helping out.

  • #445015 — yajl, libuvc: CMake 4 compat
  • #445579 — docker-tini, openhmd: CMake 4 fixes
  • #447855 — playwright-webkit: apply CMake 4 compat patch to overridden libjxl
  • #448902 — clblast: fix build with CMake 4
  • #444478 — magma: apply patch for CMake 4
  • #444483 — python3Packages.triton: relax build-system CMake 4 dep
  • #443947 — rocmPackages.rocm-device-libs: cmake 4 compat

  • #176312 — edk2-uefi-shell: init at 202202
  • #458517 — opencl-cts: init — Full KhronosGroup conformance test suite for OpenCL to aid in validation of ROCm bumps (ROCm includes an OpenCL runtime!)

Minecraft modding§

Core developer of the Feed the Beast Launcher (2012-2013), the dominant Minecraft modpack platform of its era. FTB's platform was later folded into CurseForge, which was acquired by Twitch/Amazon (2016) and then Overwolf (2020). ~20 merged PRs including the auto self-updating system, logging framework rewrite, window management, and performance improvements. Managed via custom IRC chatops system, source lost to the sands of time.
