+# NixOSインストール手順（SOPSなし・ディスク暗号化なし）
+
+この手順は、SOPSによるシークレット管理とLUKSによるディスク暗号化を
+使用しないホスト向けの、独立したインストール手順である。
+
+SOPSとディスク暗号化を使用する場合は、[暗号化ありの手順](install.md)を参照。
+
+## 事前準備
+
+1. [ISOビルド](iso-build.md)を参照してISOを作成
+2. USBに書き込んで対象マシンでブート
+
+## ネットワーク接続
+
+### 有線LAN
+
+DHCPで自動設定される。
+
+### Wi-Fi（有線が使えない場合）
+
+```bash
+nmcli device wifi connect <SSID> --ask
+```
+
+## SSH接続
+
+コンソールに表示されたIPアドレスに接続：
+
+```bash
+ssh root@<ip-address>
+```
+
+## インストール手順
+
+### 1. dotfilesのクローン
+
+```bash
+git clone [email protected]:moons-14/dotfiles.git ~/dotfiles
+cd ~/dotfiles
+```
+
+### 2. ホスト設定の作成
+
+`hosts/<hostname>/nixos.nix`を作成し、`hosts/default.nix`にホストと使用する
+プロファイルを登録する。ホスト固有の設定だけをホストディレクトリに置き、
+再利用可能な設定は適切なunitまたはprofileに置く。
+
+### 3. インストール先ディスクの確認
+
+```bash
+lsblk -o NAME,PATH,SIZE,MODEL,SERIAL,TYPE,FSTYPE,MOUNTPOINTS
+ls -l /dev/disk/by-id/
+```
+
+以降の操作では指定したディスクの既存データが消去される。対象を必ず確認し、
+可能であれば`/dev/sda`や`/dev/nvme0n1`ではなく、安定した
+`/dev/disk/by-id/...`パスを使用する。
+
+### 4. Disko設定の作成
+
+`hosts/<hostname>/disko.nix`を作成する：
+
+```nix
+_:
+{
+  disko.enableConfig = true;
+
+  disko.devices.disk.main = {
+    type = "disk";
+    device = "/dev/disk/by-id/<target-disk>";
+    content = {
+      type = "gpt";
+      partitions = {
+        ESP = {
+          size = "512M";
+          type = "EF00";
+          content = {
+            type = "filesystem";
+            format = "vfat";
+            mountpoint = "/boot";
+          };
+        };
+        root = {
+          size = "100%";
+          content = {
+            type = "filesystem";
+            format = "ext4";
+            mountpoint = "/";
+          };
+        };
+      };
+    };
+  };
+}
+```
+
+`<target-disk>`を手順3で確認した実際のディスクIDに置き換える。指定した
+ディスクの既存データは消去される。
+
+### 5. パーティション作成とマウント
+
+```bash
+disko --mode destroy,format,mount hosts/<hostname>/disko.nix
+```
+
+Diskoの実行結果を確認する：
+
+```bash
+findmnt /mnt
+findmnt /mnt/boot
+```
+
+### 6. ハードウェア設定の生成
+
+```bash
+nixos-generate-config --no-filesystems --root /mnt --show-hardware-config \
+  > ~/dotfiles/hosts/<hostname>/hardware-configuration.nix
+```
+
+### 7. ホストモジュールから設定を読み込む
+
+`hosts/<hostname>/nixos.nix`で、生成したハードウェア設定とDisko設定を読み込む：
+
+```nix
+{
+  imports = [
+    ./hardware-configuration.nix
+    ./disko.nix
+  ];
+}
+```
+
+### 8. NixOSインストール
+
+```bash
+nixos-install --flake ~/dotfiles#<hostname>
+```
+
+SOPSを使用しないため、age鍵の登録、シークレットの再暗号化、SSHホストキーの
+事前生成とコピーは不要である。OpenSSHを有効にしたホストでは、SSHホストキーは
+通常の初回起動時に生成される。
+
+### 9. 再起動
+
+```bash
+reboot
+```
+
+## インストール後の確認
+
+- 正しいディスクから起動できるか
+- `/`と`/boot`が意図したファイルシステムからマウントされているか
+- ネットワークと、設定している場合はSSH接続が利用できるか

+# iOS Simulator 初期セットアップ
+
+この手順は `m2` の macOS 環境で、stable Xcode と最新の stable iOS Simulator Runtime を使える状態にするためのもの。
+
+## 前提
+
+- `m2` が `workload.development` profile を有効にしていること
+- Mac App Store に Apple Account でサインイン済みであること
+- dotfiles を最新化していること
+
+Xcode 本体は `applications.xcode` が Mac App Store 版を管理する。Simulator Runtime は Apple が管理する mutable state のため、Nix store には入れず専用 dev shell から導入する。
+
+## 1. macOS 設定を反映する
+
+リポジトリ直下で nix-darwin の設定を反映する。
+
+```bash
+sudo darwin-rebuild switch --flake .#m2
+```
+
+これにより `/Applications/Xcode.app` に stable Xcode がインストールされる。
+
+Xcode のインストールで Mac App Store の認証エラーになる場合は、App Store を一度開いてサインイン状態を確認してから再実行する。
+
+## 2. iOS Simulator Runtime を導入する
+
+初回セットアップは次の1コマンドで行う。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+`ios-simulator-install` は次を順に実行する。
+
+1. `/Applications/Xcode.app` が存在することを確認
+2. `xcode-select` の Developer Directory を stable Xcode に切り替え
+3. Xcode の first-launch components を導入
+4. 利用可能な新しい hardware support components を確認
+5. 選択中の Xcode に対応する最新の iOS Simulator Runtime をダウンロードしてインストール
+6. Xcode のバージョンとインストール済み Simulator Runtime を表示
+
+途中で `sudo` の認証を求められる場合がある。
+
+## 3. インストールを確認する
+
+```bash
+xcodebuild -version
+xcode-select -p
+xcrun simctl list runtimes
+xcrun simctl list devices available
+```
+
+`xcode-select -p` は次を指していること。
+
+```text
+/Applications/Xcode.app/Contents/Developer
+```
+
+`xcrun simctl list runtimes` に iOS runtime が表示されればセットアップ完了。
+
+## 4. Simulator を起動する
+
+```bash
+open -a Simulator
+```
+
+Simulator の Device メニューから、インストール済み runtime で利用可能な iPhone を選択する。
+
+## Runtime の更新
+
+Xcode を stable の新しいバージョンへ更新した後は、同じコマンドを再実行する。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+Xcode の選択、first-launch components、hardware support、iOS Simulator Runtime の状態をまとめて更新できる。
+
+## トラブルシューティング
+
+### Xcode が見つからない
+
+次のエラーが出る場合、先に nix-darwin の設定を反映する。
+
+```text
+Xcode is not installed at /Applications/Xcode.app.
+```
+
+```bash
+sudo darwin-rebuild switch --flake .#m2
+```
+
+### Simulator Runtime が見えない
+
+まず runtime 一覧を確認する。
+
+```bash
+xcrun simctl list runtimes
+```
+
+iOS runtime がない場合は再度インストーラーを実行する。
+
+```bash
+nix develop .#ios -c ios-simulator-install
+```
+
+### Command Line Tools 側を参照している
+
+```bash
+xcode-select -p
+```
+
+が `/Library/Developer/CommandLineTools` を指している場合でも、`ios-simulator-install` が `/Applications/Xcode.app/Contents/Developer` へ切り替える。
+
+手動で直す場合は次を実行する。
+
+```bash
+sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
+```

-# カスタムISOビルド
+# カスタムインストーラー ISO
+
+`hosts/installer` から、NixOS 26.05 ベースの `x86_64-linux` 用インストーラー
+ISO を作成する。installer ホストは Home Manager を使用せず、`base` プロファイルと
+ホスト固有のインストール支援設定だけを含む。
 
 ## ビルド
 
+flake 対応の Nix が利用できる環境で、リポジトリのルートから実行する。
+`x86_64-linux` 以外のマシンで実行する場合は、対応する Linux リモートビルダーが
+必要になる。
+
 ```bash
 nix build .#nixosConfigurations.installer.config.system.build.isoImage
 ```
 
-## ISO書き込み
+生成された ISO は次の場所にある。
+
+```text
+result/iso/nixos-minimal-*-x86_64-linux.iso
+```
+
+ファイル名に含まれる NixOS のバージョンとリビジョンは、`flake.lock` の更新に応じて
+変わる。生成物を確認するには次を実行する。
 
 ```bash
-# USBデバイスの確認
+ls -lh result/iso/*.iso
-lsblk
+sha256sum result/iso/*.iso
+```
 
-# 書き込み（/dev/sdXは実際のデバイスに置き換える）
+## USB メモリへの書き込み
-sudo dd if=./result/nixos-minimal-*.iso of=/dev/sdX bs=4M status=progress
+
+書き込み先はパーティション（例: `/dev/sdX1`）ではなく、USB デバイス全体
+（例: `/dev/sdX`）を指定する。この操作は指定したデバイスの内容を上書きするため、
+サイズ、モデル、マウント先を確認する。
+
+```bash
+lsblk -p -o NAME,SIZE,TYPE,MODEL,MOUNTPOINTS
+```
+
+USB のマウント済みパーティションをアンマウントしてから、`/dev/sdX` と
+`/dev/sdX1` を確認した実際のデバイス名に置き換えて書き込む。パーティションが
+複数ある場合は、それぞれをアンマウントする。
+
+```bash
+sudo umount /dev/sdX1
+sudo dd if=result/iso/nixos-minimal-*-x86_64-linux.iso \
+  of=/dev/sdX bs=4M conv=fsync status=progress
 sync
 ```
 
-## ISOの特徴
+書き込み完了後、USB を安全に取り外して対象マシンから起動する。
 
-- SSH鍵認証でrootログイン可能
+## 起動後の接続
-- 有線LANはDHCPで自動設定
+
-- WiFiは`nmcli`で手動設定可能
+有線 LAN は DHCP で自動設定される。Wi-Fi を使用する場合は、インストーラーの
-- disko/sops/ageなどのツールを内蔵
+コンソールで NetworkManager を使って接続する。
-- ブート時にIPアドレスとヘルプを表示
+
+```bash
+nmcli device wifi list
+nmcli device wifi connect <SSID> --ask
+```
+
+起動時にコンソールへ IPv4 アドレスと簡易ヘルプが表示される。表示されたアドレスへ
+登録済みの SSH 鍵で接続する。
+
+```bash
+ssh root@<ip-address>
+```
+
+root のパスワードログインとキーボード対話認証は無効で、
+`hosts/installer/nixos.nix` に登録された公開鍵だけが利用できる。
+以降の作業は、構成に応じて次の手順を参照する：
+
+- [SOPSなし・ディスク暗号化なし](install-simple.md)
+- [SOPS・ディスク暗号化あり](install.md)
+
+## ISO に含まれる主な設定とツール
+
+- Nix flakes と `nix-command`
+- NetworkManager、OpenSSH、起動時の IP アドレス表示
+- `disko`、`parted`、`cryptsetup`、`btrfs-progs`、`efibootmgr`
+- `sops`、`age`、`ssh-to-age`
+- `age-plugin-yubikey`、`yubikey-manager`、`pcsc-tools` と `pcscd`
+- `sbctl`、`tpm2-tools`
+- `git`、`rsync`、`vim`、`wget`、`curl`、`jq`、`pciutils`、`util-linux`
