이상한 시스템: 종속성을 추가할 수 없습니다. 파일이 존재합니다.

나는 wheezy를 실행하는 데비안 armel 머신을 가지고 있고 오늘 데비안 베타 버전으로 업그레이드했습니다. 제목에서 짐작할 수 있듯이 systemd는 두 가지 측면에서 이상합니다.

1) 시작할 때 "Cannot add dependency X to Y.target, ignoring: file presents"라는 일련의 오류가 나타나지만 시스템은 정상적으로 시작되는 것 같습니다. 오류는 다음과 같습니다

2) 워치독은 더 이상 기본적으로 활성화되지 않으므로 하드웨어 워치독(부트로더에 의해 초기화되며 JTAG 액세스 없이는 플래시하지 않음)이 시스템을 재설정하게 됩니다. "systemctl -f 활성화 watchdog"을 사용하여 활성화하려고 하면 다음 오류가 발생합니다.

The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).

3) RTC에도 뭔가 이상한 점이 있는 것 같습니다. 업그레이드 이후 root 1 22.3 1.2 6372 3184 ? Ss 18:16 0:15 /sbin/init fixrtcRTC와 ntpdate가 모두 제대로 작동하는데도 프로세스가 계속 작동하기 때문입니다.

모든 시스템 경고를 억제하고 감시가 자동으로 시작되도록 하려면 어떻게 해야 합니까? 간단한 것만으로 service watchdog start도 충분하므로 이것은 확실히 시스템적인 문제입니다.
