Hi Paul, thanks for Ardour.

For anyone curious, this wiki page describes how to package and run some precompiled binaries on NixOS, particularly the section "The Dynamic Loader": https://nixos.wiki/wiki/Packaging/Binaries

NixOS tries to insist that programs reference only other paths within the nix store (e.g. /nix/store/9rabxvqbv0vgjmydiv59wkz768b5fmbc-glibc-2.30/lib64/ld-linux-x86-64.so.2 which is a specific version built by a specific compiler, rather than /lib64/ld-linux-x86-64.so.2). This is the source of the per-program isolation that enables all the nifty features of NixOS.

NixOS _does_ make exceptions to that though, for example providing both /bin/sh and /usr/bin/env at those paths.
