Hello All,
I am trying to set multiple users with passwords for modifying grub2
menu entries at boot. I know I can set a "root" user grub2 password with
grub2-setpassword. I have also been able to make a grub2 user password
using the grub2-mkpasswd-pbkdf2 command and adding
set superusers="user1"
to the /etc/grub.d/40_custom file. However, I have multiple user
administrators that will possibly need access to grub at boot (i.e. to
boot to single user mode to fix a broken configuration file). I've tried
generating two different passwords with grub2-mkpasswd-pbkdf2 and adding:
set superusers="user1, user2"
password_pbkdf2 user1 grub.pbkdf2.sha512.1000./hash1/
password_pbkdf2 user2 grub.pbkdf2.sha512.1000./hash2/
with no success. The first user account worked but not the second.
Does anyone know the correct syntax to add multiple grub2 user accounts
with different passwords in 40_custom? All tutorials I've found online
explain a single user but not multiple.
