- Add patch 0001-add-hdflush-for-reboot-or-hddown-for-poweroff.patch
A check for unmaintained disk like devices is added to be able to
flush and maybe shut them down. Also the missing sync() system
call is added for the direct halt/reboot systemctl command. Then
the system halt is used as fallback if poweroff fails for both
the direct poweroff systemctl command as well as for the
systemd-shutdown utility.
