+ seconds (or in other time units if
+ suffixed with <literal>ms</literal>,
+ <literal>min</literal>,
+ <literal>h</literal>,

+ <literal>w</literal>). If
+ <varname>RuntimeWatchdogSec=</varname>
+ is set to a non-zero value the
+ watchdog hardware
+ (<filename>/dev/watchdog</filename>)
+ will be programmed to automatically
+ reboot the system if it is not
+ 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
