Looking more closely, I see this:

--8<---------------cut here---------------start------------->8---
(define (check-file-system device type)
  "Run a file system check of TYPE on DEVICE."
  (define check-procedure
    (cond
     ((string-prefix? "ext" type) check-ext2-file-system)
     ((string-prefix? "btrfs" type) check-btrfs-file-system)
     ((string-suffix? "fat" type) check-fat-file-system)
     ((string-prefix? "jfs" type) check-jfs-file-system)
     (else #f)))

  (if check-procedure
      …
      (format (current-error-port)
              "No file system check procedure for ~a; skipping~%"
              device)))
--8<---------------cut here---------------end--------------->8---

Isn’t it already taking care of not attempting to check NFS?

Or, to get rid of the warning, what about:
?

Thanks,
Ludo’.

I've now pushed the above to master.  Closing!
