Estou tentando ativar o watchdog service (em Jessie Raspbian).
Eu instalei o watchdog e (espero) o configurei.
sudo systemctl start watchdog parece começar tudo bem
systemctl status watchdog.service mostra a execução: -
● watchdog.service - watchdog daemon
Loaded: loaded (/lib/systemd/system/watchdog.service; static)
Active: active (running) since Mon 2017-02-20 15:52:46 AEDT; 22s ago
Process: 1828 ExecStart=/bin/sh -c [ $run_watchdog != 1 ] || exec /usr/sbin/watchdog $watchdog_options (code=exited, status=0/SUCCESS)
Process: 1824 ExecStartPre=/bin/sh -c [ -z "${watchdog_module}" ] || [ "${watchdog_module}" = "none" ] || /sbin/modprobe $watchdog_module (code=exited, status=0/SUCCESS)
Main PID: 1831 (watchdog)
CGroup: /system.slice/watchdog.service
└─1831 /usr/sbin/watchdog
Quando tento ativá-lo com sudo systemctl enable watchdog , recebo essa saída estranha
Synchronizing state for watchdog.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d watchdog defaults
Executing /usr/sbin/update-rc.d watchdog enable
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, ...).
A tentativa de sudo update-rc.d watchdog enable também não foi bem-sucedida
unidades de lista systemctl | grep watchdog
cat /lib/systemd/system/watchdog.service na verdade não tem seção [Instalar]
[Unit]

ExecStopPost=/bin/sh -c '[ $run_wd_keepalive != 1 ] || false'

Como posso depurar isso, e fazer com que o watchdog seja executado na inicialização
Adicionei o seguinte a /lib/systemd/system/watchdog.service
[Install]
WantedBy=multi-user.target
watchdog agora é iniciado. Vou precisar testar para garantir que funcione!
