通常､Live USBでのブートでは変更内容が保持されませんが､persistence領域を作成することで､ここに変更内容が保持されます｡
Kali Linux Live USB Persistence
https://docs.kali.org/downloading/kali-linux-live-usb-persistence
- Live USBで起動
- ターミナル起動
- fdiskでパーティション作成
- ファイルシステム作成
- persistence領域の設定
起動するとrootで自動ログインされます｡
ターミナルを起動してfdiskコマンドで認識されているHDDを確認します｡
/dev/sdbがLive USB(64GB)になります｡

これで次回起動に｢Live USB persistence｣を選択するれば､/dev/sdb3がpersistence領域としてマウントされて､変更内容がここにoverwriteされます｡
試しにapt update,apt upgradeを実行してみましたが大丈夫でした｡
