We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

<listitem><para>Configure the hardware

watchdog at runtime and at

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
|
|
available.</para></listitem>
