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

[James Paton-Smith]

I've already added the --unrestricted option to the submenu but still
not working. Which is why I thought this might be a bug. But I
understand modifying the grub scripts is not ideal.

I can see there is already a bug upstream to add this as an option to
the /etc/default/grub config file but appears to be in limbo:

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
