contacted within the specified timeout

interval. The system manager will

ensure to contact it at least once in

half the specified timeout
|

interval. This feature requires a

|
hardware watchdog device to be
|
|
present, as it is commonly the case in
|
|
embedded and server systems. Not all

hardware watchdogs allow configuration
|

of the reboot timeout, in which case

the closest available timeout is

picked. <varname>ShutdownWatchdogSec=</varname>

may be used to configure the hardware

watchdog when the system is asked to

reboot. It works as a safety net to
|
|
ensure that the reboot takes place
|
|
even if a clean reboot attempt times
|
|
out. By default
|
|
<varname>RuntimeWatchdogSec=</varname>
|
|
defaults to 0 (off), and
|
|
<varname>ShutdownWatchdogSec=</varname>
|
|
to 10min. These settings have no

effect if a hardware watchdog is not

available.</para></listitem>
