@brian, so, for Roon to work on NixOS automatic update would have to be disabled. This is because NixOS keeps binaries in a read only, hash addressed volume called a “store.” This allows users to guaranty that their system is identical to another system by comparing the hashes of the dependencies.
When finished, the script would likely have to remove/patch the auto update functionality, then allow users to update the normal way using nix-env update roon or whatever.
That said, making progress on getting it started, turns out there are unpatched bash scripts in Appliance as well, with those fixed, I now get
[nix-shell:~/code/roon-nix/RoonServer/Server]$ sudo ./RoonServer
