+  20_*: Third party apps (e.g. memtest86+).
+
+The number namespace in-between is configurable by system installer and/or
+administrator.  For example, you can add an entry to boot another OS as
+01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
+the menu; and then adjust the default setting via /etc/default/grub.
