Restructure `computer` and `server` folders.

[soupglasses]

Is your feature request related to a problem? Please describe.

Currently a lot of folders inside ./nixos follows a set of "concepts" so to say, like hardware, mixins, modules, and roles. It seems out of place that the default configs for servers and computers are put into this top level, especially since they are both essentially single files of default.nix.

Describe the solution you'd like

This is very much up in the air, and very much for discussion. But something among the lines of ./nixos/kind/server.nix or ./nixos/kinds/computer/default.nix could be a better structure here to follow the idea of having top level "concepts".

Describe alternatives you've considered

Continuing having the ./nixos/computer and ./nixos/server folders.

Additional context

Changing this now would break the import paths. srvos.nixosModules.server is bascially the default import for all servers.

One could also add back the module names as aliases too. Either with or without a trace warning, or simply have them as top level without any kind of kind- prefix.

I am primarily focused on the folder structure, and do not see a problem with the name of nixosModules.server itself.

What is the computer one referring to? We have "server", "desktop" and "common".

I understand the tension but would rather keep the folder structure as shallow as possible. If we add more "kinds" of machines then it would make sense to create that folder.

Yeah sorry. When I stated computer I was thinking about desktop. Sorry for the confusion
