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

[James Paton-Smith]

Public bug reported:

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
