boot.initrd.services.swraid -> boot.swraid 

Since the option affects both stage-1 and stage-2, it does not make
sense to keep it within the boot.initrd namespace.

- The Caddy module gained a new option named `services.caddy.enableReload` which is enabled by default. It allows reloading the service instead of restarting it, if only a config file has changed. This option must be disabled if you have turned off the [Caddy admin API](https://caddyserver.com/docs/caddyfile/options#admin). If you keep this option enabled, you should consider setting [`grace_period`](https://caddyserver.com/docs/caddyfile/options#grace-period) to a non-infinite value to prevent Caddy from delaying the reload indefinitely.



- mdraid support is now optional. This reduces initramfs size and prevents automatic import of software RAID pools, which may not be desired. It is disabled by default in new configurations (determined by `stateVersion`), but the appropriate settings will be generated by `nixos-generate-config` when installing to a software RAID device, so the standard installation procedure should be unaffected.

- mdraid support is now optional. This reduces initramfs size and prevents the potentially undesired automatic detection and activation of software RAID pools. It is disabled by default in new configurations (determined by `stateVersion`), but the appropriate settings will be generated by `nixos-generate-config` when installing to a software RAID device, so the standard installation procedure should be unaffected. If you have custom configs relying on mdraid, ensure that you use `stateVersion` correctly or set `boot.swraid.enable` manually.
