Hi,
we are using grub2 with authentication enabled and multiple submenus.
Unfortunately it is not possible to return to a previous menu with ESC without
triggering a superuser password prompt. This is not the desired behavior in
my opinion.
I attached a patch to this email, which removes the password prompt when
pressing escape.
Actually I could not even reproduce it at first. The problem is, new
submenu opens new context and unless `superusers' is exported as soon as
we enter submenu no authentication is required at all (including
entering CLI).
I am not sure whether this is intentional, but this is definitely
unexpected. And due to complete lack of description of variable scoping
in GRUB it is also undocumented.
Options are
- simply document variable scoping and mention it in authentication
description
- propagate superusers to submenus, rely on normal export in nested
config. Still needs documentation what export actually does.
- export superusers by default and document it in description.
