nix-darwin VS nix-processmgmt

Just a shout out to nix-darwin[1]. It is nix, so initial setup is a bit involved. But then it truly makes it easy to configure everything in one place including mac defaults, homebrew apps declaratively and mas apps etc.

There is a sample config in nix-darwin repo[2].

nix-darwin does similar thing for MacOS

You can use https://github.com/LnL7/nix-darwin

There are many threads around where you can learn more about this (and why it's complicated...), but https://github.com/nix-community/home-manager/issues/1341 and https://github.com/LnL7/nix-darwin/issues/139 seem like two of the most comprehensive.

Nix is pretty usable for both desktops and headless servers. Personally, I even use it on macOS without much trouble.

My system looks like any other install of Ventura, but all of my configuration, ranging from the terminal and VS Code to macOS-specific system preferences and Safari, is done declaratively in Nix [1]. The overwhelming majority of my installed software also comes from Nix packages, with some exceptions for stuff that is not packaged yet (e.g., I have Podman Desktop, the macOS ZFS port, Lulu, yubikey-manager-qt installed through Homebrew -- fortunately nix-darwin [2] also just lets me have an set of brews/casks in my config).

It was been a bit of a nightmare at first since the error messages are kind of horrific, and there can be a lack of good examples/docs on flakes. But I think the weekend worth of time I invested was worth it since I no longer need to rely on hacky shellscripts or remember to manually configure anything.

Take a look at nix-darwin, this is what I use. It allows you to configure your system similar to NixOS including globally installed programs.

This — I still use mas and brew —-cask through the nix-darwin module, though. It’s not exactly reproducible, but it’s at least closer to reproducible and declarative.

I somewhere saw this project being mentioned: https://github.com/svanderburg/nix-processmgmt

That's nice and it showcases how Nix can create a declarative process management atop a script-based imperative manager. How is your experience with it? Also note that there's https://github.com/svanderburg/nix-processmgmt, a manager agnostic processes management framework supporting s6 among others, but your way seems a bit more straightforward.

There's a project still being developed: https://github.com/svanderburg/nix-processmgmt my understanding is that if home-manager would use it (I don't know if there is even plan to do that, it's not the same author), it would be able to work without needing systemd.

It's not really clear to me what you are asking. Are you maybe looking for nix-processmgmt? (NixCon 2020 talk: https://cfp.nixcon.org/nixcon2020/talk/TW79FU/)
