Debian Jessie에서는 재부팅 후에도 살아남는 것이 없습니다.

Debian Jessie를 기반으로 RasPBX 실행 - 일부 .conf 파일을 변경해 보았지만 재부팅 후에는 항상 다시 돌아옵니다. 처음에는 dhcp가 문제를 일으키고 있다고 생각했지만 재부팅 후에는 아무것도 살아남지 못한 것으로 나타났습니다. 홈 디렉터리에 생성한 .txt 파일도 삭제됩니다.

tl;dr - SSH 입력, 내용 변경, 재부팅, 모든 변경 사항 되돌리기.

fsck 실행을 거부합니다.

fsck from util-linux 2.25.2
e2fsck 1.42.12 (29-Aug-2014)
/dev/mmcblk0p2 is mounted.
e2fsck: Cannot continue, aborting.

또한 /dev/mmcblk0p2 마운트 해제를 거부합니다. 대상이 사용 중이라고 주장합니다.

시험을 마친:

shutdown -F -r now
