Raw Blame History

This seems to be a SUSE specific patch. Here we add the check for unmaintained
disk like devices to be able to flush and maybe shut them down. Also we add the
missing sync() system call for the direct halt/reboot systemctl command. Then we
use the system halt as gfallback if poweroff fails for both the direct poweroff
systemctl command as well as for the systemd-shutdown utility.
