nix-processmgmt VS nix-bundle

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.

(builtins.fetchTarball "https://github.com/svanderburg/nix-processmgmt/archive/6def8584c6b028c922c550859a07b989d21d6f73.tar.gz")

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/)

I admit that there is an element of, "but I chose an obscure and challenging linux variant, waaah why isn't it supported" here, but (a) there's currently no flatpak and (b) when, for goodness sakes, will major linux projects begin packaging for Nix/NixOS as a matter of course?

It's not hard, and the benefits go far outside merely supporting Nix, as e.g. a flake.nix file would allow this project to generate docker images, and appImage images, as basically afterthoughts. (See e.g. https://github.com/matthewbauer/nix-bundle.)

Nix flake support would also provide a perfectly reproducible build environment, which can help clarify dependencies, and thus help the project build achieve idempotence, but I'll save the full shill for some github issue.

In fact, I'm inclined to roll up my shirtsleeves and help make this real.

https://github.com/matthewbauer/nix-bundle perhaps?

Another way to approach this would be to advocate Nix as the build system for Flatpak or AppImage. Don't know what the status is of nix-bundle, but if it is possible to turn a Nix package into an AppImage with little extra work that would be ideal.

Nix itself is more focused on "distribute from this host with nix, to this other host with nix".

Though, here is e.g. https://github.com/matthewbauer/nix-bundle, which is supported as an experimental command in nix 2.4.

I believe this tool does: https://github.com/matthewbauer/nix-bundle

Yes, it's extremely powerful once you truly understand Nix.

There are efforts to improve documentation, but it still is lacking (I think the biggest problem is that Nix is so big, not just the OS but it can be utilized as a build system).

Just with NixOS is not exactly clear how can you for example build your custom image.

I think https://nix.dev/ is approaching the documentation from the right direction.

There are also many pieces that people built that you need to find.

For example some things that I found accidentally:

* https://github.com/matthewbauer/nix-bundle

* https://github.com/cleverca22/not-os

Unfortunately those side projects often have even worse documentation.
