It has this:

  (define (partition? name major minor)
    ;; Select device names that end in a digit, like libblkid's 'probe_all'
    ;; function does.  Checking for "/sys/dev/block/MAJOR:MINOR/partition"
    ;; doesn't work for partitions coming from mapped devices.
    (and (char-set-contains? char-set:digit (last-character name))
         (> major 2)))                      ;ignore RAM disks and floppy disks

What’s the /dev name in your case?
