    Full Disk Encryption Luks with USB keyfile and fallback to passphase

    I have a bit of a problem getting this to work. I have 2 key slots on my luks, one for passphrase, another for a keyfile.
    here is my
    cat /etc/crypttab
    sda5_crypt UUID=a928ff73-50f1-44e4-80e1-03b79905d294 UUID=341785d4-e610-49c8-b4ac-a0ec71362f21:/KLinux/keyfile.key luks,noauto,keyscript=passdev

    cat /etc/fstab
    # /dev/mapper/cryptolinux-cryptroot                           /                          ext4                errors=remount-ro            0       1
      UUID=853af3dc-9042-4144-91d1-a58dfa95b513        /                           ext4                errors=remount-ro            0       1

      /dev/mapper/cryptolinux-crypthome                         /home                  ext4                defaults                     0       2
      /dev/mapper/cryptolinux-cryptswap                          none                    swap                sw                           0       0

      UUID=341785d4-e610-49c8-b4ac-a0ec71362f21       /mnt/usb               auto                user,noauto                  0       0

    lsblk -o name,uuid,mountpoint
    NAME                        UUID                                   MOUNTPOINT

    after restart nothing happens though, it's just stuck on splash screen, what am I missing here?

    Also on my previous install of 2020.2 I could boot it with keyfile on USB, but if usb was not present it did not fallback to passphrase option.

    Did anyone get this working?
