nixos/nextcloud: doc improvements, remove httpd parts from manual (#451407)

  of the [4.3 release](https://github.com/netbox-community/netbox/releases/tag/v4.2.0),

  make the required changes to your database, if needed, then upgrade by setting `services.netbox.package = pkgs.netbox_4_3;` in your configuration.

- `pkgs.nextcloud30` has been removed since it's out of support upstream.

- `privatebin` has been updated to `2.0.0`. This release changes configuration defaults including switching the template and removing legacy features. See the [v2.0.0 changelog entry](https://github.com/PrivateBin/PrivateBin/releases/tag/2.0.0) for details on how to upgrade.

- `rocmPackages.triton` has been removed in favor of `python3Packages.triton`.

  See the neovim help page [`:help startup`](https://neovim.io/doc/user/starting.html#startup) for more information, as well as [the nixpkgs neovim wrapper documentation](#neovim-custom-configuration).

- `cloudflare-ddns`: Added package cloudflare-ddns.

- `nextcloud32`: Added for the Nextcloud 32 major release.

  See https://nextcloud.com/blog/nextcloud-hub25-autumn/ for more details on the new major version.

- `services.clamsmtp` is unmaintained and was removed from Nixpkgs.

- The latest available version of Nextcloud is v32 (available as `pkgs.nextcloud32`). The installation logic is as follows:

  - If [`services.nextcloud.package`](#opt-services.nextcloud.package) is specified explicitly, this package will be installed (**recommended**)

  - If [`system.stateVersion`](#opt-system.stateVersion) is >=25.05, `pkgs.nextcloud32` will be installed by default.

  - If [`system.stateVersion`](#opt-system.stateVersion) is >=24.11, `pkgs.nextcloud31` will be installed by default.

  - `nextcloud30` is EOL and was thus removed.

  - Please note that an upgrade from v30 (or older) to v32 directly is not possible. Please upgrade to `nextcloud31` (or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You can upgrade by declaring [`services.nextcloud.package = pkgs.nextcloud30;`](#opt-services.nextcloud.package).

- `services.eris-server` was removed from Nixpkgs due to a hostile upstream.

- `prosody` gained a config check option named `services.prosody.checkConfig` which runs `prosodyctl check config` and is turned on by default.

However, it's possible to use e.g. `httpd` by explicitly disabling

`nginx` using [](#opt-services.nginx.enable) and fixing the

settings `listen.owner` & `listen.group` in the

[corresponding `phpfpm` pool](#opt-services.phpfpm.pools).

An exemplary configuration may look like this:

```nix

{

  config,

  lib,

  pkgs,

  ...

}:

{

  services.nginx.enable = false;

  services.nextcloud = {

    enable = true;

    hostName = "localhost";

    # further, required options

  };

  services.phpfpm.pools.nextcloud.settings = {

    "listen.owner" = config.services.httpd.user;

    "listen.group" = config.services.httpd.group;

  };

  services.httpd = {

    enable = true;

    adminAddr = "webmaster@localhost";

    extraModules = [ "proxy_fcgi" ];

    virtualHosts."localhost" = {

      documentRoot = config.services.nextcloud.package;

      extraConfig = ''

        <Directory "${config.services.nextcloud.package}">

          <FilesMatch "\.php$">

            <If "-f %{REQUEST_FILENAME}">

              SetHandler "proxy:unix:${config.services.phpfpm.pools.nextcloud.socket}|fcgi://localhost/"

            </If>

          </FilesMatch>

          <IfModule mod_rewrite.c>

            RewriteEngine On

            RewriteBase /

            RewriteRule ^index\.php$ - [L]

            RewriteCond %{REQUEST_FILENAME} !-f

            RewriteCond %{REQUEST_FILENAME} !-d

            RewriteRule . /index.php [L]

          </IfModule>

          DirectoryIndex index.php

          Require all granted

          Options +FollowSymLinks

        </Directory>

      '';

    };

  };

}

```
