Nix is a lie, and that's ok

Nix was designed to abandon the Filesystem Hierarchy Standard (FHS) for reproducibility, but graphics drivers expose a fundamental exception. Because user-space libraries like libGL.so must match the host kernel and GPU, NixOS and Home Manager introduce an intentional impurity: a global convention path at /run/opengl-driver/lib. This effectively re-introduces an FHS-style convention. Users running Nix on non-NixOS Linux distributions are left without this workaround, hitting the classic 'cannot open shared object file' error. Available workarounds include nixGL, manually setting $LD_LIBRARY_PATH, or symlinking host drivers to the expected path.
