[Bug 2016894] Re: grub unrestricted option only applies to default menuentry

[Julian Andres Klode]

Have you tried setting the --unrestricted option on the submenu?

In any case, modifications to grub.d scripts are outside the normal
operation of the grub2 package. It's very hard to merge them on updates,
and you really shouldn't be touching them. I think it's a mistake
they're in /etc.

If you want support for grub superuser password stuff and unrestricted
default class, I suggest submitting patches to upstream that enables
setting those from /etc/default/grub, as I don't foresee this in scope
for the Ubuntu enablement work, and the same applies to enabling the
features to work if they're not even supported by the generator.

Title:
  grub unrestricted option only applies to default menuentry

Status in grub2 package in Ubuntu:
  Won't Fix

Bug description:
  After adding a grub superuser and password, and attempting to set the
  '--unrestricted' option for all grub menu entries, I am still prompted
  for a username and password when I try to select any menu  entry that
  isn't the default 'Ubuntu'

  Steps to reproduce:
  Create a grub superuser and password
  Modify the CLASS variable in /etc/grub.d/10_linux to include the '--unrestricted' option for all entries.
  Update grub

  What happens (the issue)
  /boot/grub/grub.cfg is updated, and I can see that all menu entries include the '--unrestricted' option
  Upon reboot, I can boot the default 'Ubuntu' entry without entering a password, but selecting the 'Advanced options for Ubuntu' submenu results in a username/password prompt

  What I expect to happen
  I should be able to select any grub menu entry and boot from it. The username/password prompt should only show if you try to edit the menu entry or drop to the grub cli
