왜리눅스 민트 20이리저리 움직이고 있다1분 30초~2분i310G에서 부팅하기 느린 부팅 시간 때문에 정말 답답합니다. 지난 1주일 동안 해결책을 찾으려고 노력했지만 아직 결실을 맺지 못했습니다.
커뮤니티의 답변에 진심으로 감사드립니다.

답변1
일반적인 대답으로, 루트 로그인에 빠르게 들어가고 싶다면 하드웨어에 관계없이 systemd를 사용하지 마십시오. 이전 openrc를 사용하면 코어 2에서 20초도 안 되어 루트 로그인에 도달했습니다. (디스크 4개 + USB2 장치 5개 + LAN 2개)(*)
귀하의 배포판이 init 시스템 옵션을 제공하는지 모르겠지만, 그렇다면 주저하지 마십시오.
보다 구체적으로 추적하면 CPU 성능에 관계없이 시간이 걸리는 여러 작업이 표시됩니다. 예를 들어 systemd-analyze 키 체인에서 가져온 내용은 다음과 같습니다.
FSCK: (파일 시스템 확인) fsck 옵션 세트, 파일 시스템 수, 유형, make 옵션, 부팅 시 깨끗했다는 사실에 따라 다름... => 이러한 옵션을 모두 확인합니다. CPU가 무엇이든... 이러한 작업에는 시간이 제한되어 있습니다.
시간 동기화: 시스템이 시간 서버에 시간을 요청하는 것 같습니다. 가용성에 따라 응답하는 데 시간이 얼마나 걸립니까... 부팅할 때마다 이 기능을 구현해야 합니까? 종료 시 저장된 값과 배터리로 지원되는 내부 시계의 신뢰성이 만족스럽지 않으신가요?
네트워크 관리자:아마도 이더넷 LAN 링크를 설정하는 데 이것이 필요하지 않을 것입니다. 나는 당신이 Wi-Fi에 연결하고 싶지 않다고 가정합니다. 시간이 오래 걸릴 수 있습니다. 특히 네트워크 관리자가 사용 가능한 Wi-Fi 네트워크를 열거할 때까지 기다립니다. 이더넷 링크를 통해 인터넷 라우터에 연결하는 편리한 방법이 있는 경우. 선호하다!
어쨌든 네트워크 관리자는 사용자 입장에서 특별한 지식이 필요하지 않기 때문에 편리하다는 점은 인정합니다. 그러나 기본적인 보안상의 이유로 이 서비스가 초기화 시 즉시 시작되는 것을 원하지 않습니다. 내 말은, 자신에 대한 몇 가지 온전한 점검을 하기 전에 말입니다.
등...
