Clean up the nixos option tree

[Profpatsch]

Is there a guideline on where to put new options?

I can find categories like ec2, gnu, qtPlugins and zramSwap in the option root, on the same level as e.g. hardware, nix and lib.

Apart from fulltext option search it is hard to find anything in the current structure.
I’m all for flat hierachies, mind you, but designed systematically.

Ouch, that's very ugly. Those definitely should not be at top-level.

A strategy for the cleanup is needed. Since renaming options causes a lot of user breakage, a sensible deprecation model is needed first. Therefore this issue depends on #15357.

There are still zramSwap, gnu, dysnomia and powerManagement that look out of place to me. Do we have a deprecation model by now ?

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

I’ll close this for now, because I don’t think it’s an extremely important thing to do. Grepping for keywords is much easier in any case.
