답변1

PXELINUX는 다음과 같은 특수 경로 이름 규칙을 지원합니다.

::파일 이름 일반적인 파일 이름 접두사를 억제합니다. 즉, "filename" 문자열을 수정하지 않은 채 서버에 전달합니다.

IP 주소::파일 이름 (e.g. node7::filename) 일반적인 파일 이름 접두사를 억제하고 대체 TFTP 서버로 요청을 보냅니다. IP 주소 대신 DNS 이름을 사용할 수 있습니다. 점이 포함되어 있으면 정규화된 것으로 간주됩니다. 그렇지 않으면 DHCP 서버(옵션 15)에서 보고한 로컬 도메인이 추가됩니다.

이중 콜론("::")은 운영 체제 사용과 충돌할 가능성이 적기 때문에 선택되었습니다.
