Use the nixpkgs version locked by this flake for `nix-bitcoin.pkgs`.
|
|
Only relevant if you are using a nixpkgs version for evaluating your system
|
|
that differs from the one that is locked by this flake (via input `nixpkgs`).
|
|
If this is the case, enabling this option may result in a more stable system
|
|
because the nix-bitcoin services use the exact pkgs versions that are tested
|
|
by nix-bitcoin.
|
|
The downsides are increased evaluation times and increased system
|
|
closure size.
|
|
|
|
If `false`, the default system pkgs are used.
