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?
