This option provides access to the overridden result of `programs.singularity.package`.
For example, the following configuration makes all the Nixpkgs packages use the overridden `singularity`:
```Nix
{ config, lib, pkgs, ... }:
{
nixpkgs.overlays = [
(final: prev: {
_singularity-orig = prev.singularity;
singularity = config.programs.singularity.packageOverriden;
})
];
programs.singularity.enable = true;
programs.singularity.package = pkgs._singularity-orig;
}
```
Use `lib.mkForce` to forcefully specify the overridden package.
