(In reply to Richard Brown from comment #0) > Now rebootmgrctl get-strategy says best-effort Which is correct and documented this way: "off: Reboot requests are temporary ignored. /etc/rebootmgr.conf is not modified." I hope you did not restart rebootmgrd between disabling reboot and the reboot which happend? If rebootmgrd should not reboot, best is to disable the service.
