+The third (and rarely used) part of the mount parameter is the list of
+mount options used to mount the underlying filesystem. If this is not
+given, then the mount options are either the empty string or C<ro>
+(the latter if the I<--ro> flag is used). By specifying the mount
+options, you override this default choice. Probably the only time you
+would use this is to enable ACLs and/or extended attributes if the
+filesystem can support them:
+
+ -m /dev/sda1:/:acl,user_xattr
