By adding `key`, this allows users to disable this shared module or they can choose to not disable this shared module (by filtering by key before disabling)
This means users can disable all shared modules if all modules are paths or attrsets with a key:
`configuration.nix`:
```nix
{ config, ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = config.home-manager.sharedModules;
};
}
```
Or disabling just this module specifically:
```nix
{ ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = [ { key = "home-manager#nixos-shared-module"; } ];
};
}
```
Or disabling all modules when you have modules you can't disable (like lambdas):
```nix
{ ... }:
{
home-manager.users.enzime = { ... }: {
disabledModules = lib.filter (v: lib.isString v || lib.isPath v || (lib.isAttrs v && v ? key)) config.home-manager.sharedModules;
};
}
```
