The flake only defined x86_64-linux and aarch64-darwin devShells, so `nix develop` on the Jetson kits (aarch64-linux) failed with "does not provide attribute devShells.aarch64-linux.default". Mirror the x86_64-linux shell for aarch64-linux, but source CUDA from the system JetPack install (apt: nvidia-jetpack) rather than nixpkgs: wire the driver/runtime libs into LD_LIBRARY_PATH and point TRITON_LIBCUDA_PATH at the JetPack driver dir (/run/opengl-driver/lib doesn't exist off NixOS).

Problem
nix developon the Jetson kits (e.g.delta-dev1,aarch64-linux) fails:The flake only defined
x86_64-linuxandaarch64-darwindevShells.Change
Add
devShells.aarch64-linux.default, mirroring thex86_64-linuxshell (same tooling: nushell/git/git-lfs/uv-wrapped/ytt/just/prek/skim/openssl/ffmpeg).Key difference: on Jetson, CUDA comes from the system JetPack install (
apt: nvidia-jetpack), not nixpkgs. So the shell:LD_LIBRARY_PATH(/usr/local/cuda/lib64,/usr/lib/aarch64-linux-gnu/{nvidia,tegra}) so uv-installed wheels (torch, etc.) find CUDA at runtimeTRITON_LIBCUDA_PATHat the JetPack driver dir (/run/opengl-driver/libis a NixOS-only path and doesn't exist here)Test
Verified on
delta-dev1(aarch64 Jetson):nix developenters successfully,uv --version→0.11.16 (aarch64-unknown-linux-gnu), and git/just/nushell resolve.🤖 Generated with Claude Code
