Description Harald Reindl 2012-12-02 17:30:01 EST
will we ever get this dumb behavior fixed that grub2-mkconfig does NOT include --unrestricted or grub2 NOT incorrectly requests the password on a UNATTENDED boot?

the same password protection for the bootloader which was possible
for dacades with "grub-legacy" - request the password if someone
is touching the boot-entry but leave the user in peace for a
untouched boot

set superusers="root"
password_pbkdf2 root grub.pbkdf2.sha512.10000.*********************
export superusers

results in a password request every time

menuentry 'Fedora (3.6.8-2.fc17.x86_64)' --unrestricted --class fedora --class gnu-linux

brings back the behavior only request a password if you try to boot
as example in single-user-mode or modify any kernel-param

"--unrestricted" is the key to bring back this behavior
this was NOT the case for all grub2-releases

it is a MAJOR DEGRADE of a bootloader having problems to secure
it with a password because it is HARDLY needed if you want to be
sure that nobody bypass your boot-configuration after you made
sure your BIOS settings are protected with a password and boot
from any external media is disallowed
