アクティブにして起動し、再び触れることなく終了できるように、持続可能なClamAVオンアクセス検索システムサービスを作成しました。
サービスを手動で開始でき、正常に実行されます。ただし、期待どおりにログインした後は自動的に起動しません。どちらの場合も、アクティブなネットワーク接続はありません。
次のログ出力（投稿の最後の出力セクションにあります）が手がかりになる可能性があると思います。
rc.local[1188]: ERROR: ClamClient: could not connect to remote clam daemon, Couldn't connect to server
rc.local[1188]: ERROR: Clamonacc: daemon is local, but a connection could not be established
しかし、サービスを手動で開始することはできますが、自動的に起動できない理由はまだ理解されていません。

多くの試行錯誤の終わりに、研究中に見つけたさまざまなオプションを試したところ、期待どおりに機能する組み合わせが見つかりました。
以前の失敗の原因は、次のようなものが不足していたためだと思います。

Requires=clamav-daemon.service
そして

1回の成功したリリース後、2回目のテストが失敗したことに気づきました。私はこれが同じセッションの以前のテストのためにまだ存在する1終了コードを試みたために起こったことに気づきました。mkdir /tmp/clamonacc-quarantine変更を明確に/説明するために説明を追加しました。
rc.localスクリプト
#!/bin/sh -e
dir=clamonacc-quarantine
# Check if the folder for quarantining already exist. If it does, go straight to the main process
if $(/bin/ls /tmp/$dir)
then
# Run the main process, start logging and move any infected files to the quarantine folder
/usr/bin/clamonacc --log=/var/log/clamav/clamonacc.log --move=/tmp/$dir/
else
/bin/mkdir /tmp/$dir
/usr/bin/clamonacc --log=/var/log/clamav/clamonacc.log --move=/tmp/$dir/
fi
exit 0
プロセスがアクティブです。
