Keep the old name working for backward compatibility, but remove it from the documentation. --- diff --git a/man/systemd-system.conf.xml b/man/systemd-system.conf.xml index 4dd4bf0..e403fa5 100644 --- a/man/systemd-system.conf.xml +++ b/man/systemd-system.conf.xml @@ -127,7 +127,7 @@ RuntimeWatchdogSec= - ShutdownWatchdogSec= + RebootWatchdogSec= KExecWatchdogSec= Configure the hardware watchdog at runtime and at reboot.
