MariaDBはバインドマウントの使用を開始しません

新しくインストールしたKubuntu20.04にMariaDBをフレッシュインストールします。 「ストック」データベースを使用してMariaDBを正常にセットアップした後、正常に実行されていました。次に、/ var/lib/mysqlの元の内容を移動して名前を変更し、バインドマウントを使用して、実際のデータベースを新しい/ var/lib/mysqlフォルダーに取り込みました。再起動後、実際のデータベースは正しいフォルダにあり、正しい権限がありますが、MariaDBサーバーは起動しなくなります。私はすでにこの手順をKubuntu19.04、Kubuntu 19.10、Manjaroなどで正常に使用しています。Fedora31、OpenSUSE、Mageiaなどでは機能させることができませんでした。
systemctl statusmariadbとjournalctl-xeの出力は次のとおりです。

まったく同じバージョンのMariaDBlのManjaroでこれを実行してもよろしいですか？ログは質問の中で10.3.22に言及しています。 Manjaroリポジトリで確認できることから、現在出荷されているバージョンは10.4です。

10.4以降、すべてのシステムテーブル（ユーザーテーブルを含む）はAria形式であり、古いバージョンではMyISAM形式です。これは、10.3以前で10.4にアップグレードされたデータベースを起動しようとした場合に予想される種類のエラーです。
