There is only 1 partition on the micro SD card, /boot is on there.
Using a label results in the same error:

dracut: Checking ext4: /dev/disk/by-label/cuboxf18arm
dracut: issuing e2fsck -a  /dev/disk/by-label/cuboxf18arm
dracut: cuboxf18arm: clean, 98087/1957888 files, 788822/7816704 blocks
dracut: Remounting /dev/disk/by-label/cuboxf18arm with -o rw
EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts:
(null)
dracut: Mounted root filesystem /dev/mmcblk0p1
dracut: Switching root
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100
