네트워크 인터페이스가 실패할 때 서비스를 중지하는 방법은 무엇입니까?

서비스가 있는데 다음과 같은 경우 서비스를 시작하고 중지하고 싶습니다.특정 네트워크 인터페이스위아래로 움직입니다 ( eth0저의 경우). 문서와 게시물을 읽고 아래 장치에 접속했는데 불행히도 작동하지 않습니다.

명확히 하자면, 제가 원하는 것은 eth0올라갈 때 my-service.service시작 하고 eth0내려갈 때 멈추는 것입니다 my-service.service.

문제의 인터페이스는 관리 systemd-networkd되며 고정 IP와 DHCP 서버가 있습니다.

systemd를 사용하여 이 작업을 수행할 수 있는 옵션이 있습니까? 아니면 유일한 옵션은 다음과 같은 다른 서비스입니다.networkd-dispatcher?

시스템은 Yocto 프로젝트에서 만든 systemd250.4 및 systemd-networkd.
