[Bug 718670] Re: authorisation not applied to submenus

[Enrique Hernández Bello]

This bug is not related with grub.d scripts nor 'Previous Linux
versions' submenu. GRUB does not propagate the superusers variable to
any submenu.

I think that is preferable to set a local variable by menu and submenu
instead of a global variable. In Debian/Ubuntu, no superusers variable
is defined by default, so the administrator must be aware to include
autorization rights in all submenus.

In this case, it's needed to modify the "10_linux" script to include
superusers variable into 'Previous Linux versions' submenu.
