 The above steps, performed in a more privileged mount namespace,
 have created a bind mount that
-obscures the contents of the directory
-.IR /mnt/dir .
+obscures the contents of the shadow password file,
+.IR /etc/shadow .
 For security reasons, it should not be possible to unmount
 that mount in a less privileged mount namespace,
-since that would reveal the contents of the directory

 Suppose we now create a new mount namespace
 owned by a new user namespace.
