어리석게도 다음을 통해 /etc/fstab의 내용을 삭제했습니다.

echo xxxx xxxx xxxx xxx > /etc/fstab

서버는 여전히 정상적으로 실행되고 있습니다. 다음 재부팅 시 /etc/fstab의 내용을 어떻게 복원할 수 있습니까?

이 파일을 생성한 아나콘다에 대해 기억하는 것이 있습니까? 파일을 재생성하는 데에도 사용할 수 있나요?

기억나지 않는(주석 처리 여부와 상관없이) 스왑 항목과 UUID 항목을 복원하고 싶습니다. 이 두 항목 외에는 스스로 복원할 수 있습니다.

이 두 항목이 시스템 재부팅에 중요합니까?

파일은 /etc/fstab실제로 매우 간단했습니다. UUID 항목(아마도 주석 처리됨)과 스왑 파일 항목뿐이었습니다. 그런 다음 항목을 더 추가하려고 시도했지만 실수로 삭제했습니다.
