複数のインストールメディアに対応したUSBメモリーの作成 (exFAT対応) の備忘録
USBメモリー
パーティション構成
・ 128GiBのUSBメモリーの例
| /dev/ | 用途 | フォーマット | 設定容量 | 使用容量 |
|---|---|---|---|---|
| sdX1 | MBR | 無し | 1GiB | 1GiB |
| sdX2 | EFI | vFAT | 256MiB | 18MiB |
| sdX3 | DATA | exFAT | 113GiB | 28GiB |
・sdXは各自の環境に合わせて読み替えの事
USBメモリーのパーティション/フォーマットを変更するので保存されたものが削除される事を理解した上で作業して下さい
initramfsの変更
USBメモリーのexFATフォーマット領域にアクセスするためinitrd*を変更
- モジュールの追加（以下を存在すれば取り込む）
| モジュール名 |
|---|
| libaio1 |
| libblkid1 |
| libc-l10n |
| libgcrypt20 |
| libgnutls30 |
| libmount1 |
| libpcre3 |
| libselinux1 |
| libsmartcols1 |
| libtinfo5 |
| libzstd1 |
| mount |
| fuse |
| libfuse2 |
| ntfs-3 |
- スクリプトの変更
| 主な変更点 |
|---|
| ファイリングシステムの制限をしている部分にexfatとntfsを追加 |
| ロードモジュールにfuse、fuse3、exfat、ntfs3を追加 |
| ISOファイルをRAMディスク上に転送 |
| 無人インストール関連ファイルをRAMディスク上に転送 |
作業時の気づき
- 変更前のスクリプトのバグでエラーが発生しその後ろの処理が行われていなかった
- exFATとNTFSは検索先ファイルシステムから外されていた
- busyboxのmountだとfuseが使えない
- RAMディスク上に転送すればISOファイルと無人インストール関連ファイルに容易にアクセスできた
- /var/log/syslogの出力処理まで進まずに停止する場合があった
- /lib/modules/カーネルバージョンが異なる場合があった
- /lib/modules/カーネルバージョン/kernel/fs/にfuseとexfatが無いとアクセス不可だった
（分かる人にはあたり前かもしれないけど）
