Currently, as the OS disk, it mounts on boot with the default values set 
by Fedora;

==] /etc/fstab [============
/dev/mapper/luks-bd252fe0-a16f-4a14-ad4e-b99a0d4c0716 / 
       ext4    defaults,x-systemd.device-timeout=0 1 1
UUID=eca11946-68d8-444c-90f2-ad65455caf6d /boot                   ext4 
   defaults        1 2
