I haven’t taken the plunge into home manager yet, but I’ve done this with my `/etc/nixos/configuration.nix`.

My approach is to keep my configuration in a git repo, with clones on my home and work machines.

I have an import like `adminInfo = import ./admin-info.nix {};` in `configuration.nix`. And I have two files in the repo:

`home-admin-info.nix`:

```nix
{}:

{
  user = "matt";
  hostName = "alpha";
  domain = "mchenryfamily.org";
}

```

`work-admin-info.nix`:

```nix
{}:

{
  user = "mmchenry";
  hostName = "mmchenry-nixos";
  domain = "work.com";
}

```

The only thing that’s not version controlled in git is the `admin-info.nix` symlink, which points to the appropriate `*-admin-info.nix` on each machine.

Then elsewhere in `configuration.nix`, I can refer to these variables, e.g. `networking.hostName = adminInfo.hostName`.

I also have `hardware-configuration.nix` symlinked to `home-hardware-info.nix` or `work-hardware-info.nix`, since the machines need different kernel modules etc.
