현재 Ubuntu의 Upstart는 네트워크 이벤트를 생성하지 않습니다. 대신 전통적인 sysvinit를 호출합니다. 기본적으로 NetworkManager가 설치되어 실행 중입니다. 시작하기 위해 네트워크 이벤트를 내 보내지 않고 runup-parts 디스패처 (/etc/NetworkManager/dispatcher.d/)를 포함하고 있으며, 이는 ifupdown의 run-parts 디스패처 (/etc/network/*.d/)에 의존합니다. 특히 /etc/network/if-up.d/ 및 /etc/network/if-down.d/에 관심이 있습니다.
먼저 암호화되지 않은 ssh 키 쌍을 설정하여 프롬프트없이 포인트를 마운트 할 수 있습니다. 스크립트를 작성하여 /etc/network/if-up.d/에 넣고 실행 가능하게 만드십시오. 다음은 UbuntuForums에서 발견되었으며 충분했습니다.
