nixpkgs 8b8c811 (2026-08-08) removed services.clightning.enable,
causing btcpayserver.nix:124 to throw 'option does not exist' on
nixos-rebuild (your error). Sovran uses lnd only, never clightning,
but evaluation still throws.
- Add modules/vendor/nix-bitcoin/stubs.nix to provide missing options
as false stubs: clightning, clightning-rest, liquidd, fulcrum,
lightning-loop/pool, joinmarket
- Guard btcpayserver/rtl/lnd/mempool clightning/liquidd references
with config.services ? X checks
- Trim enable-tor.nix onionServices for removed services
