以前に私がこのようなことをしたことがあります。CentOS 8はAPFSパーティションを自動的にマウントしません。
このオペレーティングシステムでパーティション情報検出機能を見つけたいです（新しいCentOSをインストールしました）まだインストールしておらExFATず、ファイルシステムをNTFSマウントしていません。APFS
Linuxカーネルがデーモンを介してインストールExFATおよびNTFS削除されたドライバに関する情報を正常に検出しましたが、まだ検出されていませんAPFS。
私は本を読んでいます。
次の内容をお読みください。
4つのディスクパーティションを持つUSB外部SSDがあります。パーティションのファイルシステムは次のとおりです。
APFSExFAText4NTFS
カーネルバージョンを使用しています

新しいAPFSファイルシステムを検出するためのUdev適応（開発）が不足していますか？ 、そう思います。。
カーネルバージョン5.8にAFPSパーティション検出機能が含まれる可能性はどのくらいですか？
コードを受けたいのですが、どこから始めるべきですか？ とは別にブログ1 ブログ2 pdf1。
どのようにblkidこれら（サービス）デーモンと対話していますか？
メタ情報を抽出しようとしています。APFS

答え1
デフォルトでは、すべてのユーザースペースツールは（util-linuxの）（lib）blkidを使用してブロックデバイスのファイルシステムを検出します。 UDiskはUDevのデータを消費し、UDevはそのルールでblkidを実行します。
カーネルはこれとは関係がなく、ファイルシステムの署名を検出するためにカーネルモジュールは必要ありません（blkidはディスク/ブロックデバイスから直接データを読み取り、署名（バイナリデータ）を内部データベースと比較します）。カーネルモジュール（またはヒューズモジュール）は、実際にデバイスを取り付けるときにのみ必要です。
APFSサポートutil-linux 2.33に追加されましたそしてCentOS 8には2.32しかありません。したがって、util-linux UDiskは手動でアップグレードしないとAPFSドライブを自動的にマウントできません。
