systemd-networkd를 통해 고정 IP 설정을 시도했는데 모든 것이 제대로 작동했습니다. 사용자 정의 파일을 제거하고 장치를 다시 시작한 후 eth0이나 wlan0이 시작되지 않았습니다. 그들이 DHCP에서 주소를 다시 가져오기를 바랍니다. 제가 보는 디버그 로그를 확인하세요.

그러나 이전에는 ipv6 주소가 성공적으로 할당되었습니다. Failed to set DUID: No medium found이 오류에 대한 참조 를 찾을 수 없습니다.
답변1
문제는 systemd에 마운트된 tmpfs가 덮어쓰기 /etc/machine-id때문에 기본 빈 파일로 생성된 systemd를 재정의하는 /etc에서 overridefs를 사용한다는 것입니다./ets/machine-id
따라서 DUID가 비어 있으므로 DHCP6 클라이언트는 DUID를 설정할 수 없습니다 /etc/machine-id. 재부팅 후에도 지속되도록 /etc/machine-id를 오버레이 파티션(존재하지 않는 경우)에 복사하여 문제를 해결했습니다.
