Reproduced with 1.3.0ish.

To reproduce this bug:

# mkdir -p /foo/bar
# mkdir -p /bar

Add this to the file-systems field of your config.scm:

(file-system
  (device "/foo/bar")
  (mount-point "/bar")
  (type "none")
  (check? #f)
  (needed-for-boot? #t)
  (flags '(bind-mount)))

Your system should fail to boot.
