I am observing that ShutdownWatchdogSec setting in system.conf
In man page, for ShutdownWatchdogSec , I see :
" It works as a safety net to ensure that the reboot takes place even if a
clean reboot attempt times out. "
I am not clear what is meant by 'clean reboot' and 'times out ' here
For testing, I have set it to 5 sec
***@re1:~# grep ShutdownWatchdogSec /etc/systemd/system.conf
and I have my.service , which on stop will sleep for few minutes
# cat /etc/systemd/system/my.service
But I dont see hardware watchdog being kicked in.
Is this a bug in ShutdownWatchdogSec ? if not am I missing any config ?
I did some research and found below links which talk about effect of
as described in above pages, one option seem to be to lower value of
reboot.target but that solution is still about software watchdog and not
about hardware watchdog.
My requirement is to put upper bound time limit of reboot, and once upper
limit is reached, i want to kick in hardware watchdog
Could you please let me know how do I achieve this ?
