-Auto create encrypted swap with random key for every boot. Problem is that given block device will be filled with random data when swap is created. So label / UUID is lost for next reboot. Need to use direct device names or use symlinks like ''/dev/disk/by-id/…'' which can be also unsafe and can hit another partition.+Auto create encrypted swap with random key for every boot.
